Senior Software Developer

acemate is building an AI learning & teaching platform for higher and further education institutions. We have strong traction, secured funding and are entering an exciting growth phase. We're looking for a passionate Senior Software Engineer / Developer to drive our product forward and help us scale.

About acemate

Founded in 2024, acemate has quickly become the leading AI learning platform for higher and further education, trusted by top-tier institutions across four countries, including University of Cologne, WHU and the German Chambers of Commerce and Industry (IHKs).

• Our Mission: Democratizing access to personalized learning. We don’t believe that AI will replace educators. Instead, we empower them to design and deliver personalized learning experiences at scale.
• Our Growth: We've raised pre-seed funding and are growing rapidly. While we focus on higher and further education in the DACH area today, we're already expanding into new regions and markets.
• Our Culture: We’re a young, driven team passionate about tackling the toughest challenges in education. We embrace builder culture and minimize scheduled meetings for ad-hoc discussions and maximized focus on coding and creating.

Tasks

What You'll Do

Serving as a Software Engineer and a vital part of our core team, you will heavily shape our technical strategy and architecture. You will assume end-to-end ownership over the backend systems driving our features, encompassing everything from the database schema up to the API response and observability dashboard.

• End-to-end ownership: You will take complete accountability for every feature you develop—spanning from database modeling and API design all the way through to deployment and monitoring. You will iterate on our architecture to guarantee that our Effect & TypeScript codebase remains highly maintainable, type-safe, and rigorous.
• Build complex logic, not just simple endpoints: You will concentrate on the heavy backend lifting that drives the product. Rather than merely shipping basic CRUD operations, this involves architecting the asynchronous workflows, AI pipelines, and authorization rules required to resolve difficult user problems.

Past examples of projects you might tackle:

• Complex authorization engine constructed to manage the increasing intricacies of various institutional settings through the combination of ReBac and ABAC
• Complex AI pipelines that retrieve visual and textual content from documents by synthesizing multiple models and embedding topics into knowledge graphs
• Migration away from a monolithic fullstack environment toward an entirely typesafe API layer developed in Effect

Tech Stack:

• Backend: Effect.ts, Hono, oRPC, Bun, Typescript
• Database: PostgreSQL (via Supabase)
• Infrastructure: Cloudflare (Workers, Workflows, R2, KV, Hyperdrive), Google Cloud (Gemini, Cloud Run)
• Tooling: Axiom, Sentry, PostHog, Langfuse, Stripe
• AI: Vercel AI SDK

Please do not worry if you aren't an expert in every technology listed on day one. We trust in your capacity to rapidly learn and adjust to novel tools and frameworks on the job.

Requirements

What We're Looking For

• 2+ years of software engineering experience with strong TypeScript skills
• Startup experience: You’re comfortable in fast-paced, evolving environments
• Balanced AI approach: You knew how to code before Cursor and Claude Code, but understand how to leverage them effectively
• Product passion: High identification with our mission to transform education
• Bonus: Experience with authz systems, infra/devops, AI, or frontend work (Next.js/React)
