Senior Backend Engineer (Berlin)

GeneralMind is a Berlin-based AI startup building an autonomous AI-powered supply chain automation platform. Backed by Lakestar, Leo Capital, and leading angels with $12M raised in January 2026, we're eliminating manual, inbox-driven workflows in enterprise supply-chain operations - automating Sales Order processing, Purchase Order lifecycle management, Accounts Payable, and Accounts Receivable. We integrate with SAP, Oracle, Microsoft Dynamics, and Salesforce, serving companies like a $16B food retailer and an $8.2B resources company. Tasks Backend Ownership • Own the backend end-to-end: service architecture, API design, reliability posture, and long-term technical direction. • Be the person who knows how everything fits together - and who other engineers come to when they're not sure where something belongs. • Set the bar on code quality, service boundaries, and shared abstractions across the engineering team. • Make foundational decisions with conviction, document the reasoning, and evolve them as the system grows. Python Services & Production Systems • Design for failure: retries, timeouts, graceful degradation, and recovery paths built in from the start. • Write code that is easy to operate - observable, testable, and straightforward to debug at 2am. • Understand the runtime, not just the framework. Know when the problem is the code, the config, or the infrastructure. Workflow Engineering & Temporal • Design and build durable workflows using Temporal - long-running processes, async coordination, saga patterns. • Own workflow observability: know when a workflow is stuck, degraded, or silently wrong before a customer notices. • Think carefully about idempotency, failure modes, and replay semantics — not just the happy path. • Evolve workflows without breaking running instances; manage versioning with intention. Reliability & Systems Thinking • Detect regressions before they become incidents; build the tooling to catch them early. • Own the operational posture of the services you build: alerting, runbooks, on-call readiness. • Identify structural debt before it compounds; propose refactors that are thoughtful, not just correct. Requirements • Experience: 6+ years building and operating backend systems in Python, with clear ownership of production services - not just feature delivery. • Python depth: Non-negotiable. You make deliberate choices about async vs. sync, framework selection, and performance tradeoffs. You know the language well enough to have opinions. • Temporal or equivalent: You've used Temporal (or a comparable workflow engine) in production. You understand durable execution, not just task queues. • Reliability instinct: Idempotency, retries, and observability are part of how you design, not afterthoughts. • End-to-end ownership: You're comfortable being the person who holds the full backend picture. You identify what's broken or missing before you're asked, and you don't leave the system worse than you found it. • A real spike: We're a strong team with broad coverage. What we're hiring for is someone who brings a 10x improvement in an area we're currently underinvested in. That might be workflow systems, data infrastructure, AI-native backend patterns, or deep domain expertise. We don't know exactly what shape it takes - but you should know what yours is, and be able to articulate why it matters. Find Jobs in Germany on Arbeitnow
