Job Description

We're hiring a Sr. Software Engineer
- Reliability Engineer who can code across the stack and cares deeply about reliability. You'll design and build infrastructure, observability tooling, and operational systems-treating resilience and debuggability as first‑class concerns. You'll own projects end‑to‑end: from architecture → code → deployment → production. You'll split time between infrastructure-as‑code, incident response, system improvements, and mentoring. You'll work on a team that ships quality systems while maintaining operational excellence across a platform serving millions of dealership transactions daily.

• Design and implement resilience initiatives: redundancy, failover, disaster recovery, data protection.
• Write infrastructure-as-code (Terraform); manage 50+ AWS accounts with infrastructure patterns.
• Own system health: proactively maintain application performance, minimize downtime, ensure consistent user‑experience.
• Evolve team’s SRE standards and practices.

• Build observability into systems: logging, metrics, distributed tracing, alert design.
• Improve monitoring frameworks; enable faster incident detection and resolution.
• Design dashboards and alerts that help teams understand system behavior.
• Partner with application teams on service instrumentation.

• Drive significant reductions in cloud spend through architectural improvements and resource utilization.
• Review infrastructure for efficiency; identify and eliminate waste.
• Balance cost, performance, and reliability in design decisions.

• Build production systems, APIs, internal tools, and automation with clean, well-tested code.
• Design for maintainability, operational simplicity, and reliability.
• Participate in code review and technical design discussions.
• Mentor junior engineers on code quality and architectural thinking.

• Participate in on‑call rotations; debug and resolve production incidents.
• Conduct postmortem analysis; drive systemic improvements.
• Develop operational procedures and runbooks.

• 5+ years software engineering, platform engineering, or infrastructure engineering experience.
• Strong coding in Python, Go, Java, or equivalent; writes clean, testable code.
• AWS hands‑on: EC2, RDS, DynamoDB, S3, Aurora, Lambda, VPCs, Athena.
• Terraform or equivalent infrastructure-as-code experience.
• Docker and container orchestration (Kubernetes or similar).
• Debugging on Linux and Windows platforms; able to troubleshoot complex systems using logs, metrics, and architectural knowledge.
• System design thinking: can architect scalable systems and reason about trade-offs.
• Availability for rotational on‑call duties outside of standard business hours may be required.
• Bachelor's degree in a related discipline and 4 years' experience in a related field. The right candidate could also have a different combination, such as a master's degree and 2 years' experience; a Ph.D. and up to 1 year of experience; or 16 years' experience in a related field.
