Role Description
As a Backend Engineer, you'll help build and scale the systems that power our AI-driven research platform. This is a systems-level role - ideal for engineers who love thinking about data flows, orchestration, and performance across complex distributed systems.
You'll have the unique opportunity to:
  • Ship quickly
  • Architect and scale backend systems that support high-throughput LLM interactions, vector search, and multi-agent orchestration.
  • Stitch together AI infrastructure across model providers, data stores, and internal APIs to create cohesive, performant systems.
  • Own reliability and observability, helping us evolve our database (Postgres / ClickHouse) and job orchestration systems.
  • Prototype new backend capabilities (retrieval pipelines, caching layers, async task queues) that let us build faster and smarter.
  • Shape our engineering culture
About You
We're looking for product-minded backend engineers who:
  • Are based in NYC and excited to work 5 days a week in person
  • Are excited by the intersection of AI infrastructure, financial systems, and backend engineering
  • Have experience owning backend projects end-to-end - from architecture through to production
  • Are strong in Python and TypeScript
  • Have worked with PostgreSQL and care about data modelling, reliability, and system design
  • Are comfortable building APIs, internal tools, workflows, and infrastructure that support real customers
  • Are eager to contribute to product decisions, not just execute tickets
  • Feel like you are never building fast enough

Bonus points for experience working on:
  • Billing, payments, usage-based pricing, or financial workflows
  • Internal infrastructure / dev tools at startups
  • Data pipelines, workflow orchestration, or event-driven systems
  • Retrieval, embeddings, or prompt orchestration

Benefits
All the usual benefits (competitive pay and equity, private healthcare etc). Unusual benefits:
  • Gym membership
  • In-office cook
  • Summers working in Greece by the beach
