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.

P-1 AI | Super SWE; Forward Deployed Engineer | SF or REMOTE (US/Canada) | https://p-1.ai
P-1 is building an engineering AGI for the physical world. Our first product is Archie—an AI engineer capable of quantitative and spatial reasoning over physical product domains at the level of an entry-level design engineer. We aim to put an Archie on every engineering team at every industrial company on earth. $23M seed led by Radical Ventures.
Super SWE - Full-stack generalist heavyweight. You've done something remarkable, go 0→1 before breakfast, and have built exceptional UIs. Architecture, front-end, back-end, infrastructure—the full gamut. High talent bar, mission-driven team. Remote (US/Canada) or SF-based; remote folks spend 1 week/6 in SF office.
Forward Deployed Engineer - Own customer deployments end-to-end. Build production AI solutions, integrate Archie into customer workflows, fine-tune models with customer data. Python + production AI experience required. Bonus: physical engineering background (aerospace, mechanical, etc.) or experience with safety-critical systems.
In addition to the links above, https://nthesis.ai/public/hn-who-is-hiring pulls the latest data, formats it in markdown, and lets you search, chat, and visualize aspects of the postings (business, role, etc.). Hope you find it useful.
Phrasing is a bootstrapped company dedicated to building the most effective and efficient way to learn a language.
I’m a polyglot myself and have always struggled for a few main reasons:
1. Apps only ever focus on taking you from 0-1, never from 1-100.
2. If you have any experience in the language, it’s really hard to pick it up after a few years.
3. Language learning apps are always ugly, clunky, ugly, and just stressful to use. And ugly.
4. No apps support maintaining and learning multiple languages simultaneously
5. Apps only ever support the major languages, leaving minority languages in the dust
So, I set off to build my dream language learning application, and a quick 2 years and 10,000 hours later I’d built Phrasing.
It’s launched, it’s live, it has (happy) paying daily users, and I myself am using it to learn 18 languages. The product is ready to go, and the business is already growing organically.
I’m looking for someone cracked to come in in a co-founding capacity and eventually take over the backend (elixir) codebase from me.
No experience is required so long as you’re passionate, talented, and hungry.
If you’re interested, and located in Europe, send me an email at hn@phrasing.app.
EQTY Lab | Software Engineers (Fullstack / AI ), or DevRel | SF, LA (looking for local, but wfh if cool) | 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, or devrel equiv, 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 better performance for agents.
We're building AI-powered CAD tools to transform hardware development — think next-gen design workflows powered by custom ML models. We're a fast-moving startup, working with bleeding-edge tech at the intersection of mechanical engineering and AI.
We're looking for a versatile ML engineer to help us scale: develop and deploy custom models and prototype tools that make complex design work simpler and faster.
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.
Splash Tech| Backend Mid-Senior/Senior | Remote( +-2 EU CET) | Full Time | https://splash.tech/
We’re a small UK-based free-to-play gaming company with a distributed EU team, growing fast after recent success and scaling our backend platform. We’re looking for two roles, from mid-senior to senior engineer with at least 5+ years of experience.
Backend: Strong in backend development, ideally Java, but open to those willing to learn. DevOps experience is a plus, or a strong desire to build it.You’ll be expected to do devops as part of this role.
Fullstack: FE and APIs, you’ll also be asked to write SQL and some Java Controllers that access data. It’s ok if you don’t know Java, but our controllers are written in Java and you’ll need willingness to learn.
Our stack includes Java, Python, TypeScript, Angular, SQL, AWS, Kubernetes, Postgres, Trino, Flux, Flagger, and Terraform.
Our engineers must be able to think product-first, and take a task from idea to production, work across the full cycle. You must write your own code, AI assistance is fine, but you must be able to produce all your work independently.
We are looking for candidates that can write SQL, our approach when it comes to the DB is SQL first. We also value clear thinking and communication, you should be comfortable sketching simple architecture or flow diagrams (boxes and lines, nothing formal) to explain your ideas.
To apply, please send an email to jack[at]splash.tech with the subject “Backend Hackernews 2025” or “Fullstack Hackernews 2025”.
Please send any git/bitbucket/source-forge project that represents your coding otherwise I’ll ask you to complete a small test project.
