Job Description
Head of Backend Development
Nexus Mods
• Own the backend architecture: APIs, data models, pipelines, and service boundaries. • Drive our backend-first approach: push complexity into the backend, keep clients thin. • Champion monolith-first architecture and avoid service sprawl unless scale demands it. • Set standards for API design, consistency, testing, observability, and developer experience. • Guide critical decisions around metadata, mod manifests, dependency modelling, and install reliability for the Desktop App. • Lead and mentor backend engineers across pods (Ruby/Rails, PHP and platform services). • Create clarity through standards, expectations, architectural guardrails. • Level up the team through coaching, technical guidance, and structured growth paths. • Build a culture of ownership, pragmatism, collaboration and psychological safety. • Promote the doctrines: simplicity, problem-first thinking, documentation discipline, and quality. • Ensure backend teams ship value weekly with predictable, fast delivery. • Unblock engineers quickly bias to action over committee paralysis. • Manage cross-team dependencies and escalate blockers early. • Balance short-term delivery with long-term platform health. • Own uptime, performance, and resilience across mission-critical systems. • Partner with SRE/Infra to improve CI/CD, monitoring, logging and incident response. • Ensure systems can scale to millions of users and billions of downloads. • Lead root-cause analysis and build a culture of calm, transparent incident handling.
