This role sits within a high-calibre backend engineering team responsible for building and evolving the core systems that power the merchant experience across a global payments platform. You will help design and deliver the services that support everything from merchant onboarding to daily operational workflows, ensuring a seamless and reliable experience at scale. The environment is highly technical, distributed, and product-driven, with a strong emphasis on ownership and end-to-end delivery. You will work on complex backend systems that handle real payment flows and must meet strict standards for reliability, performance, and correctness. Collaboration with engineers, product, and platform teams is central to shaping cohesive merchant-facing capabilities. This is a fully remote, fast-paced setting where engineers are expected to thrive in ambiguity and take initiative. The role offers the opportunity to influence architecture and contribute directly to a mission-critical product area.
Accountabilities:
- Take ownership of backend features across the full lifecycle, from design and development through deployment and production monitoring, ensuring clarity on progress, risks, and outcomes.
- Design and build scalable backend services that support merchant account experiences, with strong focus on reliability, performance, and fault tolerance in a distributed systems environment.
- Contribute to architecture discussions, propose system improvements, and advocate for maintainable service design, clear contracts, and engineering best practices.
- Monitor production systems, proactively identify issues, and support incident resolution with a strong sense of accountability and operational awareness.
- Collaborate closely with cross-functional engineering teams on scoping, code reviews, and technical decision-making that shapes platform evolution.
- Maintain high engineering standards by producing clean, testable, production-ready code and actively improving shared technical practices across the team.
Benefits:
- Fully remote-first and globally distributed working model
- Competitive share options
- Minimum 25 days of annual leave with uncapped holiday policy
- Co-working space access and global workation opportunities
- Annual company retreat and remote team gatherings
- Private medical insurance (location dependent)
- Learning and development budget to support continuous growth
- Home office setup allowance (where applicable)
- High-quality equipment provided for your role
- Broad set of additional perks depending on location
Requirements:
- Strong backend engineering experience with the ability to independently deliver production-ready software from ambiguous requirements.
- Solid understanding of distributed systems principles, including failure modes, scalability, and system reliability at production scale.
- Hands-on experience designing and working with RESTful APIs and backend services in modern cloud-based environments.
- Proven ability to own features end-to-end, including monitoring, deployment, and post-release operational support.
- Confidence in participating in architecture discussions, challenging design decisions, and contributing to technical direction.
- Experience in fintech, payments, or infrastructure-heavy systems is a plus, but strong engineering fundamentals are most important.
- Comfortable working in remote-first environments with high autonomy, ambiguity, and shifting priorities.
