About the Role
We are seeking a Senior Backend Engineer to build and own production backend systems supporting core payments and data infrastructure. This role is ideal for an experienced engineer who thrives in a fast-moving, high-growth environment and is comfortable taking ownership of ambiguous projects from concept through production.

You’ll work primarily with TypeScript/Node.js, building APIs, services, data models, and internal tools where reliability, correctness, and performance are critical.

Experience

  • 5–12 years of backend engineering experience
  • Experience independently owning a project or product area end-to-end
  • Payments experience required
  • Experience working at a high-growth technology company
  • VC-backed startup experience is a strong plus
  • Experience collaborating across teams such as engineering, risk, and data science is a plus

Technical Skills
  • Strong production experience with TypeScript/Node.js - MUST HAVE on resume
  • Strong SQL and relational database experience
  • Experience with AWS, Lambda, and serverless architectures
  • Python proficiency is a plus
  • Experience with data pipelines, ETL, or Snowflake is a plus
  • Strong API, service, and data-model design skills

What You'll Be Doing
  • Build and own production backend systems supporting core payments and data infrastructure
  • Design APIs, services, data models, and contracts used by multiple teams
  • Build highly reliable systems with an emphasis on correctness, performance, and scalability
  • Create internal tools that help teams review data, understand decisions, and operate more efficiently
  • Take ownership of ambiguous projects end-to-end, including defining the problem, proposing solutions, shipping production releases, and iterating
  • Improve the reliability, latency, and correctness of systems that directly impact payment decisions and the customer experience
  • Collaborate across engineering, risk, data science, and other teams to solve complex technical problems

Education
  • Bachelor's degree in Computer Science or a related technical field


Ideal Profile
You’ll be successful in this role if you are comfortable operating with a high degree of ownership and autonomy. Priorities can change quickly, so you should be able to work through ambiguity, make sound technical decisions, and move projects forward without requiring heavily specified tickets or extensive process.

Candidates coming primarily from highly structured or legacy technology environments may find this environment challenging. We are looking for engineers who have demonstrated stability in their career and who are accustomed to the pace, ownership, and changing priorities of a high-growth company.
