Responsibilities
- Ensure Platform Reliability & Uptime: Design and evolve systems that maintain high availability, predictable performance and operational stability. Drive improvements in uptime, resilience and operational discipline as the system scales.
- Engineer for Scale & Performance: Strengthen how our distributed services behave under load. Identify bottlenecks, optimize critical paths and design systems that scale with growing traffic and complexity.
- Advance SRE & DevOps Practices: Embed reliability engineering practices across the platform - defining SLOs and SLIs, improving incident response, reducing operational toil and making production behavior measurable and actionable.
- Evolve Cloud & Infrastructure Systems: Continuously evolve Polar’s infrastructure baseline and determine when the current stack needs to evolve. Improve infrastructure-as-code, environment management and operational safety mechanisms.
- Strengthen Deployment & Operational Safety: Refine CI/CD systems, rollout strategies and rollback mechanisms to ensure changes are safe, observable, reversible and fast to deploy.
- Improve Observability & Debuggability: Advance logging, metrics and tracing standards so engineers can quickly understand, debug and resolve issues in production.
- Collaborate across Engineering, Risk & Legal: Work closely with product and infrastructure engineers, as well as risk and legal stakeholders, to translate evolving regulatory requirements into clear technical abstractions while maintaining long-term platform reliability and health.
Requirements
- Deep systems thinking: You anticipate failure modes, design for idempotency and consistency, and think carefully about how distributed systems behave in production.
- Security- and compliance-aware engineering mindset: You build with auditability, principled access control and regulatory constraints as first-order design considerations.
- End-to-end ownership: You are comfortable owning features from infrastructure and backend systems all the way to shipping functionality that powers the product.
- Strong product judgement: You know when to move fast while ensuring that correctness, auditability and long-term system integrity take precedence.
- High-ownership collaboration: You thrive in small teams, collaborating closely across engineering to evolve the platform architecture and take shared responsibility for the long-term health of the system.
- Strong backend expertise - you design clear, durable APIs and build systems that are resilient under real-world load and edge cases.
- Highly proficient in SQL and data modeling - you reason rigorously about long-term data correctness, performance and reliability across large datasets.
- Strong production debugging and observability instincts with an ability to trace complex issues across services and understand how to prevent them in the future.
- Experience building or operating distributed systems with strong reliability and operational requirements.
- 5-8+ years of engineering experience, building and scaling customer-facing SaaS or fintech products in a high-growth environment.
- Experience in payments and billing infrastructure - subscription lifecycles, transaction orchestration, refunds/disputes, payouts and financial state management.
Nice to Have
- Open source contributions or side projects/apps to showcase.
Benefits
- Meaningful ownership: Small team & large surface area. You’ll directly influence how the company and platform scale.
