about the role
We’re looking for a Frontend-focused Full-Stack Engineer who will take end-to-end ownership of the two products our partners use every day:
- Partner Portal – a web app where restaurant managers manage menus, orders, and performance.
- LANCH OS – our internal operating system for growth, logistics, and brand ops.
Key Responsibilities
- Lead development of new Partner Portal and LANCH OS features using React, TypeScript, and modern state-management patterns and build on the first AI first operating system in the F&B Sector.
- Build and consume our internal FastAPI + PostgreSQL APIs to ensure type-safe, performant data flows.
- Build reusable UI components, design systems, and testing frameworks that scale across brands and geographies.
- Own the full software lifecycle - ideation, technical design, implementation, CI/CD, release, and observability - on GCP.
- Independently drive day-to-day UI/UX design and team up with external designers on larger feature launches to deliver pixel-perfect, accessible interfaces.
- Pair with backend and data engineers to optimize queries, automate partner invoicing, and integrate third-party delivery platforms.
- Set the bar for code quality, documentation, and engineering best practices as we grow the team.
About LANCH
LANCH, the fastest-growing consumer company in DACH, is seeking a talented and motivated Fullstack Engineer to join our dynamic team.
Founded in 2023 and headquartered in Berlin, LANCH partners with restaurants and top creators to launch delivery-first food brands such as Happy Slice pizza, Loco Chicken, and the new Korean-style Koco Chicken. Beyond virtual kitchens, we are rolling out a network of physical restaurants and retail brands (“Happy Chips”, “Loco Tortillas”) that already reach thousands of supermarkets. Backed by +€30 million in Series A funding (Feb 2025), our Tech & Data team is building the platforms - LANCH OS and the Partner Portal - that power everything from menu management to supply-chain automation.
about you
What will make you thrive at LANCH:
- 2+ years of hands-on experience shipping customer-facing web apps, with at least one React + TypeScript project owned end-to-end.
- Deep understanding of modern frontend architecture: component composition, state management, and design-system theming.
- Comfortable moving down the stack - able to sketch clean REST/JSON or GraphQL contracts, read and extend Python/FastAPI code, and write pragmatic unit & integration tests.
- Cloud-native mindset: containerised development with Docker, automated CI/CD via GitHub Actions, and production workloads on GCP.
- Quality champion: you automate testing, set up monitoring/alerting, and keep documentation as crisp as your code reviews.
- Product intuition: you enjoy talking to restaurant managers or ops teams, turning fuzzy workflows into elegant UIs that save them stress and manual work.
- Bias for action and ownership: thrive in ambiguity, iterate quickly, and measure impact rather than completeness; you’re happiest when yesterday’s idea is in today’s production deploy.
- Collaborative communicator - fluent in English; conversational German.
- Growth mindset: new frameworks, new cuisines, new brands - whatever scales LANCH, you’re keen to learn and teach.
- Eager to work mostly on-site in our Berlin Prenzlauer Berg office.
