Staff Engineer (Full Stack)

## About the role Feeld is building a world where everyone is more intimately connected to each other and themselves. We're an inclusive, human-centred product with a distributed engineering team. We're hiring a Staff Engineer (Full Stack) to raise the reliability and operability of our production systems across backend and mobile integration. This role exists now to improve how we detect, respond to, and prevent production incidents, and to strengthen the engineering practices (documentation, runbooks, quality bars) that help teams move quickly without compromising stability. This is a hands-on individual contributor role with significant cross-team influence: you'll lead through technical decisions, incident leadership, and pragmatic improvements to systems and process. ## Team context - Reporting line: Sits on the Platform team reporting to the Head of Platform Engineering. Works closely with engineering leadership and partners day-to-day primarily with backend engineers. - Scope & influence: You'll collaborate across squads to improve production ownership, reliability, and backend↔mobile integration patterns. - Ways of working: Remote-first, async-friendly, high trust; you'll be expected to communicate clearly in writing and help teams adopt consistent operational practices. ## What success looks like Within your first year, you will have: - Reduced incident frequency and/or impact through concrete reliability improvements (e.g., better alerting, safer deploy patterns, guardrails, playbooks). - Made incident response more effective (clear ownership, faster MTTR, better post-incident follow-through). - Delivered improvements to backend/mobile integration that reduce breakages and production risk. - Established (or materially improved) documentation and operational standards that other engineers consistently use. ## What you will do - Own reliability outcomes across critical backend services and their integration with mobile clients (React Native). - Lead technical problem-solving during incidents: coordinate response, diagnose root causes, communicate status, and drive to resolution. - Build and evolve monitoring/observability (dashboards, alerts, tracing, logging) that enables fast detection and diagnosis. - Drive post-incident reviews (blameless) and ensure learnings become durable fixes (tech changes, runbooks, automation, process updates). - Improve engineering safety and quality: guardrails, safer migrations, feature-flag practices, rollout strategies, and resilience patterns. - Partner with product, design, QA, and engineering early to align delivery plans with operational risk and reliability needs. - Strengthen documentation and onboarding: architecture notes, runbooks, service ownership docs, and "how we work" guides. - Mentor engineers through pairing, reviews, incident shadowing, and pragmatic coaching on production ownership. ## Requirements Must-haves - Significant experience building and operating production backend systems at scale, including debugging distributed systems and pe
