Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

We move fast, build thoughtfully, and keep a sustainable 40-hour pace.

EQTY Lab | Software Engineers (Fullstack / AI ), DevRel | SF, LA (But you work remote all you want) | Full Time | https://www.eqtylab.io/

We are hiring software engineer(s) to help innovate on applied agentic applications and governance/alignment at runtime.

Specifically, you will help us release and further enhance https://github.com/eqtylab/cupcake - a solution derived from our Claude Code feature request for hooks. We believe hooking into the agent harnesses will be critical for scaled adoption; ambitions for purely LLM-driven trusted behavior exist today- but we must empower those responsible for run-time with deterministic guarantees. We do so by hooking into the harnesses - Claude Code, and now supported by Cursor, soon Gemini CLI. Beyond coding agents, we look to apply this to web harness agents, whether it's LangChain, Google ADK, etc.

We are looking for an engineer that can:

  - help develop across the full stack from an integration perspective (build the supporting bindings and SDK abstractions for web-based frameworks)

  - create quality demonstrations/tutorials/advocacy

  - continue to advance on the forefront of agentic security as well as productivity/better performance.

Novig | Multiple Roles | New York | Onsite | Full-time

Novig is rebuilding sports betting from first principles as a prediction market exchange. Legacy sportsbooks are extractive middlemen with misaligned incentives, dark patterns, and predatory mechanics. We're creating the alternative: a transparent exchange where users trade against each other at fair odds.

We're building core infrastructure around order routing, risk management, data pipelines, low-latency networking, and market integrity at scale. We write Rust extensively. We believe correctness, performance, and expressive code are necessities rather than luxuries. Ideal candidates care deeply about infrastructure, security, and performance. It certainly won't hurt to also care about prediction markets, traditional markets, or well-designed distributed systems.

Tech stack: Rust, Node, PostgreSQL, Kafka, Linux, distributed systems.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced FULL-STACK ENGINEERS who can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Rapid deployment and iteration of experimental software changes across firmware, control software and UI

- Modelling buildings in code and finding the right UI for operators to edit them

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Puma.tech | Remote-first with PST overlap | iOS/MacOS, Android, Ai/ML, Growth | https://puma.tech

Hi all, I’m Yuriy, founder of Puma.tech. Previously worked as software engineer & developer advocate at Cloudant (YC S08, Acq. by IBM), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).

We have two products:

1. Puma iOS & Android – browser with built in LLMs & Wallets. Private by design.

2. Puma AI app for Mac – ChatGPT/Atlas, but with ability to pick different model providers and fall-back to local-first ones for data privacy.

Would love your help building and growing both.

We value Optimism, Kindness, Curiosity, Speed and Grit.

Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth

We’ve raised a few rounds from some of the best builders in crypto and ai:

Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO, Neeva, Greylock), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.

How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.

Thank you!

Ascento | Zurich, Switzerland | Full Stack | https://www.ascento.ai

Ascento develops autonomous security robots that patrol outdoor areas to detect and report. All in support of security guards. We stay away from conflict, just robots driving circles around buildings in remote boring places. The technical challenges however, are far from boring.

We are looking for a full stack engineer to join as a core member of the off-robot software team. This is the software that plans, configures, operates and creates insights from data collected from the robots. You would work across the whole cloud-stack, consisting of Frontend (React), Backend (Typescript / Go), Infra (Terraform / AWS / GCP).

The cloud software team is still small, meaning you get a chance to help set priorities, guide long-term architectural direction and figure out how to best help our users. We celebrate pragmatism, we work hard to make simple systems and we help each other to hyperfocus.

Sounds like the place for you? Drop an email to sijmen@ascento.ai. I'm curious to read what about this ad caught your interest.
