Senior Backend Engineer

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 Backend 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

As a Backend Engineer on our core team, you'll play a major role in shaping our technical roadmap and architecture. We'll give you full autonomy over the foundational systems that power our product. This spans everything from designing the initial database schema up to writing API responses and setting up observability dashboards.

• End-to-end system ownership: You'll take full responsibility for the infrastructure you build, handling the entire lifecycle from data modeling and API design all the way to deployment and ongoing monitoring. You'll also iterate on our core architecture, making sure our Effect & TypeScript codebase remains highly maintainable, type-safe, and incredibly solid.
• Build complex logic beyond basic endpoints: Your primary focus is the heavy lifting of our platform. Rather than just wiring up simple CRUD operations, you'll design the advanced asynchronous workflows, intricate authorization rules, and sophisticated AI pipelines needed to actually solve hard user problems.

Examples of projects you might work on:

• Robust authorization engine designed to handle complex permissions in various institutional setups by combining ABAC and ReBac
• Advanced AI pipelines built to extract text and visual data from documents using multiple models, then mapping those concepts directly into knowledge graphs
• Architecture migration shifting our core backend away from a fullstack monolith to a strictly type-safe API layer using 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

Don't worry if you aren't familiar with every single tool on this list from day one. We trust your ability to learn quickly and pick up modern frameworks as we grow.

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)
