Welcome to the Agentic Commerce Era

At Commerce, our mission is to empower businesses to innovate, grow, and thrive with our open, AI-driven commerce ecosystem. As the parent company of BigCommerce, Feedonomics, and Makeswift, we connect the tools and systems that power growth, enabling businesses to unlock the full potential of their data, deliver seamless and personalized experiences across every channel, and adapt swiftly to an ever-changing market. We believe in harnessing AI responsibly to unlock new possibilities, and we’re looking for individuals who use it intentionally to solve problems, accelerate outcomes, and expand what’s possible in their role. Our purpose is to help businesses confidently solve complex commerce challenges so they can build smarter, adapt faster, and grow on their own terms. If you want to be part of a team of bold builders, sharp thinkers, and technical trailblazers who shape the future of commerce, this is the place for you.

The Commerce Payment integrations team is looking for a Software Engineer who wants to make an impact at every level of society by powering innovators, creative thinkers, entrepreneurs, and business owners around the world to be successful at every stage of their growth.

The Commerce Payment integrations team is responsible for building, operating, and continuously improving payment integrations on the BigCommerce platform - one of the most business-critical and revenue-sensitive areas of the product.

Our team builds payment gateway integrations that help merchants securely process payments and support scalable, high-performance, and flexible checkout experiences.

What The Team Owns

  • Designs and maintains payment integrations functionality and APIs, including cart-to-order flows and payments processing
  • Ensures high availability, performance, and correctness for checkout and payments related services, given their direct impact on merchant revenue
  • Partners closely with Product to evolve checkout and payments capabilities while balancing quality, security (PCI), and speed of delivery
  • Owns incident management and on-call responsibilities for checkout services due to their critical nature

The Commerce Engineering organisation is on a mission to build the leading SaaS eCommerce platform. We work closely with engineering teams across multiple domains, product managers, designers, business stakeholders, and external partners to build a platform where we can easily and securely deliver new and alternative user experiences. Our team brings together people with varied experience and strengths, and we iterate, learn, and build great software together.

What You'll Do

  • Build high-quality front-end features using React and TypeScript, with a focus on clarity, performance, and maintainability
  • Refactor legacy or complex areas of the codebase to improve readability, testability, and long-term health
  • Identify and fix issues across the stack, ensuring solutions are robust and scalable
  • Collaborate closely with product managers, designers, and other engineers to define requirements, refine stories, and deliver predictable outcomes
  • Provide thoughtful code reviews, offer technical guidance to less experienced engineers, and contribute to a culture of continuous improvement
  • Help shape the technical direction of the team through practical suggestions, hands-on implementation, and identifying opportunities to reduce friction or complexity
  • Contribute to improving our front-end developer experience, including building tools, testing practices, and performance optimisations
  • Ensure technical decisions support our goals of quality, performance, reliability, and security
  • Work with and contribute to open source codebases, including evaluating, extending, and maintaining shared libraries and tools where appropriate

Who You Are

  • You have at least 3 years of hands-on experience building front-end applications with React and TypeScript, and you’ve worked on complex or long-lived codebases
  • Education: Preferred Minimum Bachelor's degree in CS, EE, SW, CE, MIS; or equivalent experience
  • You write maintainable, well-tested code and care about leaving things better than you found them
  • You’re comfortable working in existing systems as much as building new ones, and you enjoy simplifying code, refactoring, and untangling complexity
  • You’re a clear communicator who can explain technical details and trade-offs to both engineers and non-engineers
  • You take ownership of outcomes, follow through on commitments, and hold yourself to a high standard of reliability
  • You enjoy mentoring and supporting others, and you contribute positively to the team’s culture and technical growth
  • You stay up to date with modern tools and approaches without being dogmatic. Your goal is to find the right solution, not the trendiest one
  • You’re proactive, curious, and comfortable working independently when needed while still being a strong collaborator

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
