About the role

About the role

Our vision

A world in which organizations can focus on their actual work — instead of grant logistics and bureaucracy. We're democratizing the funding market through transparency and accessibility.

Our mission

We're building the first fully digital end-to-end platform for nonprofit grant applications: complex processes automated, administrative overhead reduced.

Your role

As a Senior Software Engineer you build the product end-to-end — backend, frontend, infrastructure, and the AI pipeline at the core of the platform. You'd be one of our first engineering hires: you own problems from the conversation with our grant team through to production, and you shape how we work technically.

What you'll do

Ship features end-to-end, independently — including the UI

Extend our AI pipeline: prompt engineering, context management, cost control, multi-provider setup (Bedrock, Anthropic, OpenAI)

Build out our evaluation practice: own prompt quality, model selection, and regression detection

Run and debug production (Sentry, CloudWatch, Postgres performance)

Work closely with our grant team — you build from real user problems, not tickets

Help shape architecture, standards, and the technical roadmap

How we'll measure success

Our central measure is the time it takes from starting a new project to delivering and submitting the applications. Everything we build — shipped features, platform reliability, the quality of our AI output, every manual step we automate — feeds into that cycle time. And ultimately into what actually matters: our customers' ability to get their projects funded.

Nice to have

German at B1 or above — our customers and product are German-first; the team works bilingually, but the right person without German works too

Experience with AI agents and tool-calling workflows in production

Experience with Terraform

What you bring

  • Several years with TypeScript and Node, plus real depth in Postgres (JSONB, query performance, migrations)
  • Confidence across the stack: Next.js 15 / React Query on the frontend, Express and BullMQ on the backend, AWS (ECS, RDS, Terraform) for infrastructure
  • Hands-on experience with AI pipelines in production — beyond simply calling an API
  • Strong debugging instinct in live systems
  • High autonomy: you ship without hand-holding and close the loop on problems yourself
  • A usability-first mindset — we have no designer; you ship interfaces that genuinely work for grant writers
  • AI-native: tools like Claude Code or Cursor are part of how you work

What we offer

  • Fully remote possible
  • Competitive compensation and participation in company success
  • Real ownership — as one of the first engineering hires you shape the product, the technology, and our standards
  • A scalable SaaS product with clear market demand and genuine social impact
  • Short decision paths and direct collaboration with the leadership team
  • Access to exclusive funding databases and modern tools
  • Team events and optional workations
