Senior Backend Software Engineer (Python) in Berlin

• Risk Engineering builds the systems that decide which subscription orders Grover approves, declines, reviews or verifies, in real time, across four markets and for both consumers and businesses
• As a Senior Software Engineer, you report to the Engineering Manager, Risk Engineering, and join a small, senior team that owns its services end to end
• You work closely with risk analysts, data scientists, and product to grow approval rate while keeping fraud and defaults in check
• Our risk decisioning platform: the rule engine, experiments and decision APIs (FastAPI, GraphQL federation) that every Grover order passes through
• New risk products, starting with dynamic pricing and counter offers, from design to production
• Integrations with credit bureaus and identity, fraud and AML providers, built to stay reliable when vendors are not
• Event-driven flows on Kafka for decisions, manual review, ID verification and bank-account checks, correct under retries, duplicates and race conditions
• Tools for our risk analysts: the manual review experience and our LLM-powered risk assistant on AWS Bedrock
• Reliability and observability of your services: Datadog monitors, on-call, runbooks and removing legacy dependencies
• The Grover Way - How We Drive Success:
• Own It: We take ownership seriously and define what success looks like. We drive shared ownership and don’t wait - we drive. We keep one another accountable and take responsibility when issues arise
• Challenge, Decide, and Commit: We engage in proactive support, active listening, and healthy conflict to reach the best outcomes. We value diverse perspectives and, once a decision is made, we commit to it fully
• Empower and Grow: We enable, trust, and coach one another toward high performance, always thinking and acting like owners. We seek growth, apply feedback, and support the development of our peers
• Respect, Transparency, and Clarity: We strive for clear, respectful, and open communication with no surprises. We simplify complex information so everyone knows the “what, why, and how”
