## About the Role Payroll is broken. Come fix it alongside a team that's as passionate as you are! At Check, you'll use creative problem-solving, critical thinking, and grit to impact every business we build. We ignore conventional role boundaries in favor of the unique strengths and values each builder brings to our team, and our mission. We simplify the complex, make a real impact, and create a better future for businesses of every size. As a Staff Software Engineer at Check, you'll combine strong engineering fundamentals and close collaboration with cross-functional partners to build software that meaningfully improves how payroll businesses operate. You'll build the platform that powers money movement, tax calculations, and compliance workflows for thousands of businesses. By turning complex infrastructure into clear, reliable systems for our partners, you'll allow teams to run payroll confidently and help thousands of people get paid. ## What You'll Do - Run at complex problems across our platform, designing and building products that translate complex payroll infrastructure into intuitive tools for operators and partners. - Own projects end-to-end, from identifying the problem and shaping the solution through design, implementation, rollout, and iteration based on real-world usage. - Be a true partner to product, design, and operations by developing a deep understanding of the workflows and challenges faced by payroll operators and partners. - Build internal and partner-facing tools that improve the visibility, reliability, and explainability of how money moves through the payroll system. - Reduce friction in our systems by improving workflows, architecture, and tooling for both developers and operators. - Role model clear, critical thinking through code, proposals, and diagrams that help teams align and move forward together. - Raise the quality bar by working in the open, giving thoughtful feedback, mentoring teammates, and helping the team ship work we're proud of. ## Who You Are - Experience with staff-level ownership and delivery of production systems end-to-end, from design through deployment and operation. - Experience building internal tools, developer platforms, or product systems that support complex operational workflows. - Ability to navigate ambiguous problem spaces and bring structure through thoughtful design and collaboration. - Comfort debugging complex systems and investigating issues that span multiple services or infrastructure layers. - Ability to articulate technical tradeoffs to engineers and cross-functional partners. - While we don't have requirements for programming languages, experience with or, at minimum, a desire to learn our current stack is helpful: Python/Django, React, Typescript, AWS, Terraform, Postgres, Temporal, Github. ## Engineering Culture at Check At Check, engineering operates as one team.
