Job description

Due to growth and internal promotions, we have multiple Senior Software Engineering roles with strong back-end focus available in various domains across the business. Report to experienced Engineering Managers who can offer you mentorship, autonomy, ownership, and a genuine investment in your growth! 
 
If you're energized by tackling complex, meaningful challenges and want to accelerate your career growth, you'll thrive here. You'll have the opportunity to shape technical direction, receive mentorship from experienced Principal Engineers, and collaborate with a thoughtful, supportive team that genuinely values your expertise.
 
The opportunities are hybrid - 2 days/week in our Liberty Village office. 
Why you'll love this role:
  • Drive product impact at a global scale - lead projects that impact positively how people experience work.
  • Work on complex, challenging projects - apply your expertise to shape architecture, influence technical direction, and mentor fellow team members.
  • Join a close-knit, high-performing team that solves meaningful problems and celebrates successes together.
  • Work alongside an experienced leadership team who is genuinely invested in your career growth.
  • Thrive in a fast-paced, high-growth environment where innovation is encouraged and your voice truly matters.
How you'll shape our software engineering practices:
  • Own major product features end-to-end - from design to deployment - with a focus on quality, reliability, and scalability.
  • Lead system design and architecture discussions - bring clarity to complex problems and shape scalable solutions.
  • Be hands-on with the codebase - lead code reviews, champion best practices, and drive technical excellence.
  • Solve complex engineering challenges using tools like Python, Go, Kubernetes, Docker, Drone, Google PubSub, React/Redux, GraphQL, MySQL, PostgreSQL, and microservices.
  • Mentor and guide engineers of varying experience levels-foster a culture of learning, growth, and continuous improvement.
  • Collaborate cross-functionally with Product and Design to align on priorities, requirements, and dependencies.
  • Lead engineering improvements - whether through better tooling, smarter processes, or adopting new technologies.
  • Stay curious - keep up with emerging tech and industry trends and provide fresh ideas.
Experience we feel will set you up for success:
  • 5-7+ years of professional experience, with at least 2 in leading backend or fullstack projects.
  • Handson experience in system design, contributing to or leading the design phase of complex, multicomponent projects and seeing them through to delivery.
  • A good understanding of system architecture, tradeoffs, scalability, and performance in realworld applications.
  • Openness to working with different modern technologies - professional experience in Python and/or Go not required.
  • Good knowledge of microservices architecture and modern distributed system patterns.
  • Excellent written and verbal communication skills, and a collaborative approach to working with crossfunctional teams.
  • A Bachelor's or Master's degree in Computer Science or a related field.
