Ascertain | NYC (Hybrid ~3d/week) | Full-time | $180k–$280k + equity | Healthcare AI | Senior Engineers: Backend, Frontend, AI

Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.

We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!

What we're building:

* A general-purpose automation platform for healthcare ops, powered by LLMs

* A system that reads unstructured documents, fills out payer forms, and explains rejections

* Tools to automate patient discharge planning in hospitals

* A foundation for making AI in healthcare safe, observable, and human-in-the-loop

What we're looking for:

* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship

* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability

* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed

More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.

Edlink | Software Engineer (Front/Back/Fullstack) | Onsite (Austin, TX) | Full-time | $150k–$180k + Equity

Edlink is a small, high-performing team building the data infrastructure that powers edtech. Our API helps 60M+ students and educators access the software they need to teach and learn. We solve hard problems — messy school data, ancient SIS platforms, massive scale — and we do it without red tape, meetings about meetings, or fluff.

We’re 23 people, all in on building fast, owning our work, and helping each other grow. We believe in high trust, deep work, strong opinions (held loosely), and building great tools that actually help people. No micromanagement. No bureaucracy. Just a team of sharp, kind engineers shipping great code and pushing each other to improve.

The role: You’ll work across our stack (TypeScript, Node.js, Postgres, Kubernetes, Vue 2/3), building powerful APIs and clean UIs that help integrate thousands of school systems. You’ll also work directly with developer clients who use our API — think Stripe for edtech.

Perks: Equity from day one, unlimited PTO, free downtown parking, paid parental leave, relocation support, and weekly team lunches.

We’re in-person in Austin because we believe startups build better products — and have more fun — when they work side by side.

Hi HN! We’re Spark, building an AI research tool to help deploy solar farms and battery plants faster.

Please reach out if you:

* Love writing code, but also care about having significant impact.

* Want to work on an AI product that helps power more homes or learn about the energy industry!

* Want to be part of an early team and shape the product and culture.

We’re funded by top investors, including AI Grant (Nat Friedman and Daniel Gross), the founders of Brex, Plaid, Helioscope (acq. Aurora Solar), and more (to be announced).

Apple | Cupertino, CA | Full-time | Hybrid work (3 days in office) | Rust + Distributed Systems

We are a small international team, with members in Cupertino, CA, and London, UK. We are looking for senior software engineers to join our team. The role involves a large amount of individual responsibility and influence over the direction of a core service.

We believe in small agile teams and their ability to deliver high-quality, high-impact software. We share code ownership and knowledge through the Agile technique of pair-programming. Our codebase is written entirely in modern Rust using the latest technologies and coding practices.

The core work includes:

* Designing, implementing, and supporting highly scalable applications and web services

* Working in Rust (e.g., asynchronous (async/await), sharing models (Sync/Send), etc.)

* Concurrent programming (e.g., locking, memory synchronization, atomic operations, etc.)

* Distributed system concepts (e.g., distributed consensus, replication, failure detection, etc.)

This role requires working with pair programming (remote and if possible in-person) and may require occasional international travel/transatlantic travel.
