Ask HN: Who is hiring? (April 2026)

Senior engineer to step into a ~30k LOC system (~300 files) and help shape it properly.

Production-style system with real complexity. Interdependent modules, async flows, external integrations.

Stack: Python/FastAPI backend, Next.js frontend, early-stage routing/AI components.

Expectations:

- quickly understand an existing codebase

- trace data flow across modules/services

- identify structural issues and bottlenecks

- make pragmatic improvements without overengineering

Starts with a deep dive and direction, with room to stay involved and build it out.

AU-based only (R&D constraints).

We're building an AI-first bioinformatics platform to empower life science researchers with agentic AI and LLMs. Backed by pre-seed funding, a government grant, and customers from biotech, agrotech, and pharma companies, we're looking for a full-stack engineer to join as a core member.

What we're looking for:

• Strong full-stack experience across Go, TypeScript, and Python (Rust is a plus)

• Hands-on AWS infrastructure work (you've built and maintained production cloud environments)

• Experience with multi-tenant architectures: isolation strategies, auth, data partitioning

• Comfort with AI/ML devops: deploying and orchestrating model-serving pipelines, managing GPU workloads, CI/CD for ML systems

• Willingness to own problems end-to-end, from system design to shipping

Nice-to-haves (not all required): LLM integration, RAG systems, HPC infra, cloud/on-prem hybrid systems

About us: We're a team of engineers and scientists with strong academic and industry backgrounds (ex-BCG, PhD in Plant Biotech and Bioinformatics, Mathematics, M.Sc. AI, PhD in Electrical Engineering). We're committed to building something impactful, technical, and genuinely useful for life science.

We're turning compliance from a bottleneck into a creative advantage for regulated brands. Clients include Monzo, Lloyds, PensionBee, and Plum. Raised £2.6m+ from Outward VC in our first 14 months.

The problem: we run multi-agent AI pipelines that evaluate regulated marketing content in real time. The model landscape moves fast and our architecture has to move with it. You'd own how these systems evolve in production, working directly with the CTO and AI engineers, while also shipping across the full stack.

Stack: TypeScript, React, React Router v7, Tailwind, shadcn/ui | Hono on Cloudflare Workers, Drizzle ORM, PostgreSQL (Neon) | Python, FastAPI, LangChain + LangGraph | GitHub Actions

We're 6 engineers. You'd have real input into architecture, tooling, and how the team operates. We use Cursor, Claude Code and Greptile day-to-day.

£75-95k + equity. Private healthcare, gym budget, hardware budget.
