Staff Software Engineer Job Summary

As a Staff Software Engineer, serves as a technical leader responsible for architecting, building, and operating scalable Ruby on Rails–based applications with a strong focus on quality, reliability, and long-term maintainability.

Shapes technical strategy across application development and site reliability practices, ensuring systems are observable, resilient, cost-efficient, and built to scale. This role requires balancing hands‑on engineering with strategic influence, making architectural decisions, modernizing legacy systems, improving CI/CD pipelines, and raising engineering standards across teams.

Operates with a strong "quality‑first" mindset, driving test coverage, contract testing, clean code principles, and shift‑left testing practices. Champions observability and production excellence, ensuring today's features are built with tomorrow's scale in mind.

Time is split between strategic planning and hands‑on execution: writing code, guiding architectural decisions, mentoring engineers, and partnering cross‑functionally to translate business needs into durable technical solutions.

This role is ideal for someone who thrives in complex environments, wears multiple hats when needed, and raises the bar for engineering excellence across teams.

• Design, develop, and maintain scalable, secure, and well‑tested applications using Ruby on Rails and complementary frontend technologies.
• Lead architecture and modernization efforts across monolith and microservice‑based systems.
• Drive high standards for clean code, automated testing (unit, integration, contract, BDD), and documentation.
• Own services end‑to‑end with a Dev Ops mindset, including CI/CD, monitoring, logging, and production support.
• Improve system reliability through observability, performance tuning, instrumentation, and proactive monitoring.
• Lead root cause analysis and post‑incident reviews, driving long‑term systemic improvements.
• Define and evolve best practices around microservices, cloud architecture, and service scalability.
• Partner with Dev Ops and SRE to improve Kubernetes‑based deployments and cloud infrastructure practices.
• Contribute to shared tooling, internal libraries, and developer productivity improvements.
• Serve as a technical decision‑maker, resolving complex architectural challenges across multiple domains.
• Influence cross‑team standards to create consistency and reduce friction across the engineering organization.
• Mentor engineers and elevate the organization’s engineering maturity through coaching and example.

• 10+ years of professional software engineering experience building and operating production systems.
• 2+ years of hands‑on Ruby on Rails experience in complex or large‑scale environments.
• Strong expertise in relational databases (SQL), data modeling, and performance optimization.
• Demonstrated experience building and operating microservices architectures.
• Deep experience with CI/CD pipelines, automated testing strategies, and deployment automation.
• Strong commitment to high test coverage and shift‑left quality practices.
• Experience with observability tools (monitoring, logging, tracing, alerting) and building highly observable systems.
• Experience operating systems in cloud environments (AWS preferred).
• Experience with containerization and Kubernetes‑based deployments preferred.
• Strong understanding of secure coding practices and defensive programming.
• Drive architectural decisions that balance quality, scalability, reliability, cost, and speed.
• Establish and enforce engineering standards across testing, CI/CD, observability, and system design.
• Lead design reviews and guide technical direction across multiple teams.
• Evaluate emerging technologies and recommend improvements to the technical stack.
• Align engineering investments with business priorities and long‑term product strategy.
• Raise the overall engineering bar through principled decision‑making and consistency.
• Mentor Senior engineers in architecture, testing discipline, and operational excellence.
• Foster a culture of ownership, accountability, and high‑quality engineering.
