About You

You're a force multiplier. You can stabilize a platform, modernize it safely, and raise the engineering bar across multiple teams. You're hands-on, you sweat reliability details, and you drive alignment without slowing delivery. 

About the role

This Principal-level role focuses on stability, reliability, and modernization across our backend systems. You will set technical direction across teams, lead modernization efforts that reduce fragility and operational load, and partner with engineering leadership to improve uptime, incident outcomes, and delivery velocity. This is a build role: you will write and ship code. 

What you'll do

• Lead architecture and implementation to improve stability and reliability across core backend systems. 

• Drive modernization: reduce legacy debt, simplify services, and migrate to scalable patterns with minimal customer impact. 

• Establish reliability guardrails: service ownership, operational runbooks, and measurable targets for availability and performance. 

• Partner with DevOps/SRE and application teams to improve observability, incident response, and postmortem follow-through. 

• Identify bottlenecks and failure modes; deliver measurable improvements in latency, throughput, and availability. 

• Create reusable patterns and reference implementations (service templates, resilience patterns, data access patterns). 

• Mentor senior engineers and tech leads; raise standards through design docs, reviews, and coaching. 

Qualifications

• 10+ years building production backend systems; demonstrated impact at Staff/Principal scope. 

• Deep experience in .NET (C#) and/or Java service ecosystems, including performance tuning and production operations. 

• Proven track record improving reliability (incident reduction, MTTR improvement, uptime). 

• Strong experience modernizing legacy systems: incremental migrations, deprecation plans, and risk-managed rollouts. 

• Distributed systems fundamentals and resilience patterns (timeouts, retries, circuit breakers, idempotency). 

• Strong operational discipline: logs/metrics/traces, alerting strategy, and root cause analysis. 

• Clear communicator who can align multiple teams and drive decisions. 

Nice to have 

• Payments, billing, invoicing, or other high-volume transactional domains. 

• Event-driven architecture experience (queues/streams; async workflows). 

• Cloud cost and performance optimization experience at scale. 

• Logistics, cargo, or supply chain experience.  

• Spanish language proficiency. 

Compensation and benefits 

We offer competitive pay and benefits designed to fuel our team's success. 

• Health and Wellness: Medical, dental, and vision plans for you and your family 

• Future-Ready: 401(k) with company match 

• Work Life Balance: Generous flexible PTO program and paid holidays 

• Grow With Us: Professional development opportunities
