We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.
This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!

We build an AI system that builds software for complex construction & infrastructure megaprojects to sell things currently only sold by service providers. To do this, we both do whatever it takes to solve complex projects' needs AND build the system that automates ourselves out of it. We just raised our seed round (25m$ valuation) and currently have 4 people, looking to hire 6-10 total this year.
== Platform Engineer Build the system that takes our jobs. Algorithms, infrastructure, shared components, agents, and internal tooling - across the full stack. Our platform engineers build everything from our custom meeting integration to AI coding agent harnesses, sandbox environments, complex shared app features and more.
== Customer Delivery Lead / Forward Deployed Engineer Help build the AI systems that run megaprojects. We’re looking for a customer-obsessed generalist who can understand complex problems and ship solutions - part product designer, part delivery lead, part AI wrangler. In this role you deploy with customers, build software that solves their problems and do whatever it takes to maximally learn about the way they run their complex projects.

We're a YC company building AI-driven turrets to stop hostile drones - where robotics needs F1-level speed.
We're looking for smart, T-shaped teammates: experts in some part of robotics who are happy to jump in wherever needed.
U.S. persons only.

This is an exceptional opportunity to work on something with real-world impact, with a team of talented & passionate folks across a wide range of domains. We are ~200 people across the world (mostly US) and growing quickly. You can reach out to me with questions at "moc.crahgih@yeffamretep".split('').reverse().join('')
We are also hiring across all teams (creative tooling, ML, computational geometry, integrations, etc.): https://jobs.ashbyhq.com/higharc
We're building an AI platform for credit unions. A variety of tools (third party integrations + RAG) backed by multiple LLM options, including OLMo, running in our own AWS infrastructure. We're a small team (I'm CTO and our first technical hire) so you'd have real ownership over the AI stack and architecture.
You'd work on retrieval over heterogeneous corpora with citations, agent orchestration and tool calling, model serving infra, and third party API integration. There's a lot of room to experiment with hierarchical retrieval, heavier upfront document processing, and custom agent tooling. Over time we're going to expand into fine tuning, more direct compute management, and some interpretability work.
Stack: Python/FastAPI, React, PostgreSQL/pgvector, AWS/OpenTofu. Looking for someone with a few years of experience building production systems.
Email me at talati@getcultivate.ai if you're interested!

LiveMap is a funded startup with a vision to build the next generation of mapping apps (think hyper-personalised Google Maps). How that looks is still being explored so we're building prototypes, getting them into customer hands and iterating quickly. We're looking to bring on a couple of people to help accelerate this development process.
As a data engineer you'll set up a data pipeline, work with product to identify relevant datasets, connect, persist and expose that data.
Working on the routing engine you'll extend off the shelf routing engines (Graphhopper) to take into account dynamic run-time preferences & attributes (think temporal).
