Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.
We’re growing fast and are looking to fill the following positions:
-Chief of Staff - https://source.network/careers/chief-of-staff
-Lead Edge AI Engineer - https://source.network/careers/lead-edge-ai-engineer
-Head of Developer Relations - https://source.network/careers/head-of-developer-relations-r...
-Lead Technical Writer & Documentation Engineer - https://source.network/careers/lead-technical-writer--docume...
We build the end-to-end platform that helps SRE/eng teams detect, manage, and learn from incidents faster—trusted by 1000+ companies (logos include Glean, Mistral, Figma, LinkedIn, Dropbox, Replit, Grammarly, etc.).

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability early 2026.
As part of our over-the-air updates “code push” product, we’ve built a custom compiler and runtime for the Dart language, primarily written by me (founder/CEO). Now that we have thousands of customers, I have many other responsibilities and need to bring on a fulltime engineer (you!) to take over primary responsibility for all of our C++ code (Dart & Flutter forks, custom runtime, compiler, etc.) and evolve it further than I could alone. Together, you and I will add obfuscation, improve our interpreter, possibly re-write method dispatch, etc. You don’t need to be a compiler/runtime expert. You do need to be capable of working on large open source projects, be comfortable with C++, want to work at a startup, work well independently (we’re remote) and want to learn and work on lots of different areas of code.
If you’ve contributed at least a little to WebKit, Godot, Firefox, or any other large open source project, are compiler/runtime curious, and want to work at a growing startup, you will likely find this role extremely rewarding.
We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, React, Dart, C++, Rust. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird

I’m the solo developer behind MouseMux (mousemux.com) - a Windows tool that enables multiple users / multiple cursors on one desktop (local + remote). It’s used in trading / multi-monitor setups, simulator & control-room (SCADA-ish) environments, classrooms, and other collaborative workflows. MouseMux is at a turning point: a wave of major new functionality is landing, especially around remote multi-user collaboration. The product is becoming significantly more capable, and I need someone who can translate that to the world - clearly and genuinely, in the niches where it shines. You’ll be the “spider in the web”:
* Talk to existing customers, capture use cases, keep relationships warm * Create simple content (short screen-recorded videos, posts, case snippets) * Find look-alike companies/institutions and do human, non-spammy outreach * Coordinate with relevant creators (YouTube/bloggers) for deep-dives * Occasionally post in relevant communities (Reddit/Discord/forums) transparently and helpfully No coding required, but you should be comfortable with technical users and Windows tooling. I’m optimizing for someone autonomous who can run with outreach + content.
Comp: contract, €60–€120/hour depending on fit, 8–16h/week. Start with a small paid test project. Bonus possible for meaningful outcomes (pilots/case studies/revenue growth).
Email: info@mousemux.com with (1) short intro, (2) 1–2 examples of content/outreach, (3) why MouseMux.
We are a small startup (<10 employees, 3 developers, recently post-revenue) in the analytics and simulation space. We sit on top of ERPs and production systems to provide financial and operational analysis for project-based manufacturing (aircraft, robotics, automotive).
Our stack is Python (Flask and Pandas), Vue 3, PostgreSQL and Clickhouse. Our infra is simple self-contained EC2 machines. We operate with high ownership, letting you impact both technical and strategic decisions.
We are looking for a senior engineer (5-10+ years) to own our integration process. You must have hands-on experience building data ingestion pipelines and ideally a background in technical pre-sales. You will start by shipping these integrations and evolve into a Solutions Architect role as the system and team mature.
To apply, please send your CV and a short background to hn-202512@stargazr.ai
StorPool is building the future of data storage. Our software runs at the heart of modern clouds, delivering <100µs latency, 113M+ IOPS per cluster, and 99.999% availability. We're profitable, self-funded, and our customers love us (NPS off the charts).
We're looking for a Senior Software Engineer to join our Core Storage team. You'll tackle genuinely hard problems: writing custom Linux drivers, optimizing lock-free data structures at nanosecond scale, building fault-tolerant distributed algorithms, and debugging issues that go all the way down to kernel internals. This isn't CRUD work - it's systems programming at its most challenging.
Competitive salary, fully remote, meaningful time off, and a yearly education budget to keep learning.
If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk.
Apply here: https://storpool.com/force/senior-software-engineer-storage-...
We’re hiring our third team member, a full-stack engineer, to work directly with the founders across the Pinetree codebase. If you were here today, you’d be shipping notifications, building out the creator studio with analytics and video management tooling, and improving our Farcaster mini app experience and onchain features like direct payments to creators.
Pinetree is building the best onchain platform for video creators: a crypto-native alternative to ad-driven video platforms that gives creators real ownership over distribution, monetization, and their content. We’re looking for someone highly autonomous who brings solutions to complex problems and wants meaningful product and company ownership.
You should have experience writing and deploying production software in TypeScript, ideally on a small (<50 person) team or other startup environment, and be comfortable working across the stack (React / React Native / Next.js, Node, Postgres). Crypto or social product experience is a plus.
Stack: TypeScript, React, React Native, Next.js, Node, Postgres
Comp: $120–200k base, 1–4% equity, health/dental/vision, unlimited PTO, remote-first, $2,500 home office budget.
Reach out to giu@pinetree.so with a resume or links to work you’re proud of.
FUTO is an organization dedicated to developing, both through in-house engineering and investment, technologies that frustrate centralization and industry consolidation.

Machine Learning Engineer - FUTO Keyboard
FUTO Keyboard is a privacy-first software keyboard for Android. Every prediction inference routine runs entirely on-device; no user data can ever leave the device. We support over 150 keyboard layouts and languages, and over 700 layout + language combinations (not all of them include dictionary or predictions)
Swipe typing is an important part of the mobile typing experience for many. Applying machine learning here poses a unique challenge due to the requirement of needing to support so many layouts and languages, as well as user-added personal dictionary words (or even layout customizations!), with limited data. We have previously collected and publicly released a US English QWERTY dataset: https://huggingface.co/datasets/futo-org/swipe.futo.org/
We are looking for a machine-learning researcher or engineer to work through these challenges and help us improve the swipe typing experience in FUTO Keyboard.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
-- Junior Software Engineer - Remote (Global), Full-Time
We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects.

To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.
Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
Oboe's goal is simple: teach one billion people one trillion things. We'll do that by building the world's first completely generalized AI-powered learning platform. Today, so much of our focus is spent on making machines smarter. At Oboe, we believe it’s time for machines to make humans smarter.
We’re a small but mighty team made up of builders who love learning, being challenged, and changing the world. If that kind of job appeals to you, we should talk.
We’re looking for a Full-Stack Engineer to work across Oboe’s technology stack, from our backend pipelines that leverage AI to generate world-class content, all the way to the interfaces that our users use to engage with that content on the web.
We’re a team of generalists, so this job will have you learning every part of the systems and features that bring Oboe to life. This is a highly hands-on role where you’ll have tremendous impact, ship real features to real users, iterate quickly, and learn a ton.
