And learn more about Lumafield below:
Lumafield was founded in 2019 to upgrade manufacturing.
We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.
Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.
We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.
Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.
We are a stealth-mode cyber and AI startup in California, backed by top-tier VCs and industry-leading angels from the top of the cyber industry. Founded by cybersecurity experts from Microsoft and Tesla, our team is on a mission to redefine the industry with breakthrough products that deliver entirely new capabilities in the cyber realm.
We’re seeking a founding team member who is a true code guru—a developer who can transform ideas into scalable, high-performance systems from the ground up. In this role, you will be responsible for end-to-end development, setting technical standards, and ensuring that our codebase reflects top-tier design patterns and best practices.

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.
Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like Autodistill [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].
We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)
We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.
We just raised our Series B round, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

We’re building the [“strong form”](https://www.youtube.com/watch?v=2ZpJXHiPwtQ&t=498s) AI agent app for business communications. We’re focusing on email initially, as it’s (1) ubiquitous (2) open and (3) has a diverse set of valuable business data. In the future we plan to expand beyond email to include all essential business communications tools, including Slack, Teams, CRMs, document platforms, project management tools, and so on.
Most people’s experience with AI today involves copy & pasting content back and forth from ChatGPT. Not only is this a terrible UX — it severely limits the transformative potential of AI.
Our goal is to unlock 10x (or greater) productivity gains for the average business user by bringing cutting edge AI together with their business communications in a single app designed for effective human-AI collaboration. With Shortwave, users can give the AI access to all of their data and then allow it to take action while still maintaining total control over its output.

There’s a massive transition happening in the video games industry right now. Gaming has become a full-blown cultural movement, and many fail to appreciate how it has already become the dominant form of leisure and entertainment for an entire generation.
But as culture has evolved, technology has advanced, and more people have gravitated toward games, the industry incumbents that run the show haven’t kept up. Our big bet is that by empowering game creators with better technology, we'll make the entire ecosystem more welcoming, connected, efficient, creative, and fun for all.
We’re an early stage startup backed by Thrive Capital, Griffin Gaming Partners, Ribbit Capital and a16z's inaugural SPEEDRUN class. Our mission is to help game creators achieve independence by building the tools they need to start, run, and scale their businesses.

Hi! I'm Pranav, co-founder of Mooncake Labs (https://mooncake.dev). We're building open-source search and analytics systems on obj-store. We just released our first project: pg_mooncake (https://github.com/Mooncake-Labs/pg_mooncake)a Postgres-Native Data Warehouse that's top 10 on clickbench (https://www.mooncake.dev/blog/clickbench-v0.1).
We’re a small and close-knit team based in SF, have been working together for many years, and love building high-performance systems from first principles. You'll be an early piece of Mooncake and will be a good fit if:
- Love low-level systems (performance engineering, databases, caching, distributed systems) - Are excited in the journey of finding PMF. We are still very 0-> 1. There’s a lot of fun that comes with this journey. - Are a team player.
If this sounds interesting to you, shoot me an email at pranav at mooncakelabs. com.
Gel is an open-source data platform built on top of Postgres. It’s designed to give developers a better end-to-end user experience than traditional SQL databases. We provide a more expressive schema modeling & query language (EdgeQL), and "batteries included" features such as built-in schema migrations and a graphical schema browser, data explorer, and access control/auth.
We offer a hosted cloud service for Gel, with the goal of doing developer-friendly cloud hosting "the right way" - we want users to use our hosted service because it's great, not because they're locked-in by restrictive licensing or cloud-only features.
We are looking for experienced SREs / infrastructure / devops engineers to help scale out our cloud. Unlike many infrastructure roles, this is not supporting a separate product team - for us, our infrastructure is our product. We are looking for people who care about not just building reliable infrastructure but also exposing that infrastructure to end-users as a seamless product.
Our tech stack is Hashicorp tools (Terraform, Consul, Nomad, Vault); Postgres; Golang with some Python & Rust; and AWS (with eventual expansion to other cloud platforms). It's a requirement that you have strong experience with Golang.
We are a remote-first company, headquartered in San Francisco, with most of the team working in US/Canada timezones and a few people in Europe. Unfortunately we are unable to provide any visa/immigration sponsorship at this time.
To apply, send your resume to jobs at geldata dot com and mention you saw this post on Hacker News.

P.S. I (co-founder) personally review all CVs from HN. I'm sorry I can't reply personally to everybody, but we do look and read through everything you send to us. And yes, we did hire a couple of wonderful people through HN and it was a great experience, I'm grateful.
Sourcegraph is how enterprises industrialize software development with AI. We accelerate and automate how software is built in the world's most important companies, including 7/10 top software companies by market cap and 4/6 top US banks.
Every successful codebase becomes large and complex. Instead of improving the product, devs spend more of their time just understanding the code and doing low-level tasks. The solution is to accelerate humans doing what they're best at--and to automate the rest with AI agents, meaning more creativity and less toil for devs.
Sourcegraph is the industrial software development platform, accelerating human devs with contextual AI and automating toil away with AI agents, and it's proven today in the world's most important companies. Our tech stack combines frontier technologies in code search, static analysis, and LLM training and evaluation. Our founders code!

1. We've found a level of product market fit (as evidenced by metrics) but we've not proven everything out yet. If you want predictability, Elicit is not for you.
2. We aim to hire people who thrive in low-bureaucracy environments, and let them loose. If you need structure, lots of support, close mentorship, or tightly-defined work assignments, Elicit is not for you.
3. We just raised a Series A, so if you want existential dread (and concomitant founding-team-upside), Elicit is not for you.

We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.
Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.
Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.
We want teammates who love learning and want to be involved in company building from the ground up - even if you aren't familiar with accounting or our tech stack. We have tier-1 investors, thousands of SMBs on the platform, and revenue has 10x'd in the last 6 months - it's a very good time to join us.
