Job Description
Senior Back End Engineer – Ruby on Rails, GO
PrizePicks
• Build and own backend services: Design and implement features across both Rails-based services and Go microservices — from API contracts through deployment and monitoring. • Support the migration to microservices: Help decompose the Rails monolith into well-scoped, independently deployable services, contributing to architectural decisions about what to extract and how. • Power internal tooling APIs: Build and maintain the backend APIs that Back Office operators depend on for real-time decisioning — projection management, risk dashboards, alerting, and member operations. • Own technical delivery: Lead the design and implementation of complex features end-to-end, from product requirements through production deployment. • Drive system reliability: Diagnose and resolve performance bottlenecks, optimize database queries, and improve resilience of backend systems under load. • Define technical direction: Propose and drive architectural decisions for your team's services, evaluating tradeoffs and communicating recommendations clearly to engineers and stakeholders. • Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III through code reviews, pairing, and technical guidance. • Improve engineering practices: Advocate for and improve best practices around code quality, testing, observability, and deployment for the team. • Collaborate cross-functionally: Work closely with Product Managers, QA, and other engineering teams to translate operational goals into well-scoped technical solutions. • Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements.
