We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.
Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.
This is not a reinvention: it’s a reflection of how we already serve our customers today.

Howdy, y'all! I am the VP of Technology here at Wallaroo.AI and I am looking to grow our team with a few more folks who are really skilled at deploying AI models and enjoy getting to work with some of the latest accelerator hardware available.
Our core mission is to automate the entire deployment lifecycle for AI models — on any hardware platform. This involves automating the packaging, compilation, deployment, and optimization steps necessary to ensure models run efficiently. Our platform allows users to target different hardware simply by changing a line of Python and rerunning the process.
To achieve this, we need people who deeply understand the complexities of AI model deployment and inference so that we can automate it across a wide variety of hardware platforms.

We also believe in compliance and security from day 0.
We're looking for someone with deep healthcare integration experience to hit the ground running. Ideally they're a pragmatic backend expert to help us scale our integration platform as we continue to grow. The expectation is deep knowledge of healthcare standards. Integrations can be a full time role, but at a startup it's necessary to wear many hats. So this individual should also feel comfortable as a generalist who can jump in at any part of the stack.

I'm Alex McHale, Lead Developer at GreenArrow Email. We're looking to add an additional developer to our team. The right candidate will have solid Go skills and can "hit the ground running" (so sorry for the cliché). Bonus if you're a polyglot who might have skills in Ruby on Rails and JavaScript.

Return (https://return.energy) is hiring a software engineer who will work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 100 people, Return’s technical team is still small (13 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform that enables our customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack/toolset is straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, self-hosted + cloud compute. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. Our web apps and platforms are often deployed multiple times per day.
Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very much open to working remotely as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss financials, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and/or have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).

Phrasing is a language learning application optimized for learning and maintaining multiple languages, and designed to take you all the way to fluency and beyond. It the professional language learning application for serious learners.
It's built with Elixir on the backend, and ClojureScript on the front end. I did try to avoid such an esoteric tech stack, but functional programming and immutable data are just too good.
I'm looking for someone to come in and take over the Elixir backend for a few main reasons:
1. I long ago hit the limit of what one engineer can do
2. I need to focus on customer facing issues for the foreseeable future, and don't want progress to stop on the backend
3. I need someone to collaborate with, if not just to discuss technical details
I'm trying to do something different with Phrasing, on both a product and a company level. I'm personally tired of the rampant enshittification of the entire web, and miss the magic of the early internet. I'm trying to make a massive product, built by a tiny team of people doing the best work of their lives.
I've got a product and some extremely happy (paying users, but this is a very early stage startup. Anyone who joins now would be paid in revenue share (of which there is some) and equity, and should be willing to put in a lot of work and take a fair amount of risk. You need to be passionate about your craft, interested enough in language learning to dogfood the product, and crazy enough to believe you can change the world.
If you're interested, please send me a well written email to hn@phrasing.app. Low effort applications will be ignored. The first step of the interview process is a 60 minute interview, so if your application does not make me say "hell yes" then it will likely be rejected.

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

Why Rootly: small, senior team; real adoption; lots of ownership and impact; AI-native workflows; customers across startup → enterprise.
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
