Rappo | https://buildrappo.com | Founding Fullstack Engineers | Remote (Preferably India) Hi, I am the founder of Rappo (agentic GTM Chief of Staff). We observed that technical startups spend way too much time in the early stages figuring out GTM.

Everyone says early PMF is crucial, but there is no streamlined support there.

VDX.tv (http://www.vdx.tv) | Remote Engineers & Developers | Full-time |

REMOTE Established company (20+ years) looking for mature generalists to contribute remotely. You can be anywhere in the world so long as you:

● Are self-motivated and can work independently

● Driven to constantly learn and are always searching for the bigger picture

● Strong in clear thinking and written communication

● Have experience with many languages but can be effective in any language

● Appreciate that all mature software solutions accumulate technical debt and understand how to continually reduce debt and complexity

● Understand how to build highly reliable systems and be responsible for taking code to production

● Understand that code simplicity and readability are more important for long term maintainability

● Want to work on challenging problems and impactful work without being micromanaged

We're hiring across disciplines for engineers who work with Unix and have fluent written and spoken English:

● Backend Servers: Strong in C, Concurrency and Distributed Computing

● Backend Servers: Strong in Java

● Infrastructure: Strong in building infrastructure tooling to program infrastructure.

● Frontend: Strong in Javascript, Typescript, React, and advanced UI and browser applications

We are private, which gives us the freedom to explore many areas without investors and profits being the sole objective.

Full-time only. Remote only. We start out on a full-time trial contract basis for up to 3 months and use this period as an extended work interview for both sides to assess fit for long-term employment.

Please email hn.remote.jobs@vdx.tv if this sounds like the right fit for you.

Stellar | Amsterdam, the Netherlands | Onsite (2 days remote OK) | €70-100k + equity | https://stellarcs.ai

Hey, I'm one of Stellar's founders. We're building voice AI for large contact centers.

Everyone thinks contact centers are boring. They're wrong. It's the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here actually helps real people: shorter wait times, 24/7 support, lower cost.

Stellar skips the robotic text-to-speech pipeline entirely and works directly with voice. Our conversations are remarkably human, also in non-English languages and local dialects, where most AI sounds like a bad GPS navigator. On top of this, we're great at integrating with the complex systems at enterprises, and meeting their compliance requirements.

We're cash-flow positive, growing fast with enterprise clients queuing up, and all founders still code. We need engineers who can jump between our Go and TS backends and React frontend. This role is perfect if you:

* Want massive ownership at a small team (not pretend "impact" at BigCo)

* Actually enjoy solving hard problems (real-time audio at enterprise scale)

* Think making AI sound human in niche dialects is a fun challenge

EU work authorization is required. No visa sponsorship available.

New Hedge fund | Sr IC Frontend Engineer | Full-time | On-site (NYC)

We are a new discretionary, tech industry focused L/S hedge fund, founded by a portfolio manager with 15+ years of experience at a well known Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at that firm as well. We are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).

We are hiring for a frontend IC engineer for our internal web application.

One of our core advantages is marrying domain experts (ie. experienced fundamental investors from top tier hedge funds) with tech talent. Our frontend (the design, the UX, the UI) _really_ matters to tie the two sides together. The quality of the data we can collect, the speed of testing new ideas, and there ultimately success is driven by the quality of our frontend -- as unintuitive as that might sound.

Our tech stack: * Frontend: Typescript, Vue3 * Backend: AWS, Cloudflare, Supabase/Postgresql, Typescript *

- We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.

- We're in full-time in office in NYC, so that's a requirement for FTE. We are potentially open to exceptional contractors located remotely.

- Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)

If you are interested, I would love to hear from you:

- Contact: ai at nx1 dotcom , I'm Alex. - Please include resume or LinkedIn and some example of something you have built (could be Github, could be your current company, anything really)

If you want to learn more about types of things we think about, I will shamelessly direct you to my blog where I write about the space (and did so more while I wasn't at any fund): https://magis.substack.com

We're looking for a Tech Lead and Senior Engineering Manager based in Los Angeles or Mexico City (hybrid). You’ll work closely with the founders, lead a small team of senior engineers, and take ownership of key technical decisions.

Our stack includes Python, JavaScript/TypeScript, Postgres, Kubernetes, and GCP.

If you're looking for thoughtful engineering work in a fast-moving environment, we’d love to hear from you.

Third time I've seen this ad. I responded to this two months ago, with twenty years experience, with the last five in ETL with Django specifically. In PST and the "one people come to with problems."

Did not even receive a reply. Certainly they've seen a worthwhile candidate by now.

I would advise people to avoid HomeVision. I did a pre interview take home assignment for them that took up a weekend, after which they didn't respond. I guess my code was sloppy or something came up. Just ghosting after the time commitment is disrespectful.
