Staff Engineer

Tasks

As a Staff Engineer, you will work across teams to build better systems and improve collaboration. You are an experienced individual contributor who combines strong technical skills with the ability to collaborate broadly—making technical decisions, supporting colleagues, and contributing to the practices and patterns we use every day. You will work on the following tasks:

• Design and build systems that scale. Backend development, making architectural decisions, and writing code to prepare our platform for the next stage of growth.
• Actively promoting AI-assisted development. We are early adopters of Claude Code. You will work with teams to establish practical workflows, measure impact, and advance the capabilities of these tools.
• Lead technical excellence initiatives with teams. Identify opportunities to improve our build process, then collaborate with engineers and tech leads to implement better standards and patterns.
• Improve how we work. Strengthen observability, testability, and resilience in our systems. Participate in incident response and drive root cause analysis that leads to real solutions.
• Empower the engineers around you. Mentor them in system design, performance, and security-focused practices. Collaborate with people, review code, and help tech leads strengthen their teams.

Requirements

• Strong experience in designing backend systems in Java or Node.js (we use Quarkus and NestJS; experience with either of these is a plus, but not required)
• Strong knowledge of system performance, observability, and secure software development

• Comfort at work across team boundaries and influence on technical decisions through cooperation rather than authority
