Senior Backend Engineer - Accounting Integrations

Requirements

• Expertise in building integrations or working on accounting systems (is an advantage, but not necessary)
• Senior-level systems thinking, able to operate “outside the team” and influence stakeholders
• Expertise in server-side languages, especially Kotlin, and experience with distributed systems, microservices, and cloud environments (e.g., AWS, Kubernetes)
• Proficiency with relational databases like PostgreSQL, testing frameworks (e.g., JUnit, Testcontainers), and observability tools like Grafana
• Strong problem-solving skills and a collaborative mindset to mentor and upskill your teammates
• A proven ability to lead large projects, manage ambiguity, and maintain high standards for code quality and reliability
• A passion for innovation and driving impactful solutions within a fast-paced scale-up environment

What you'll be doing

• Drive technical direction across integration platform + delivery work, with clear trade-offs and pragmatic sequencing
• Define and raise engineering quality standards for integrations (testing expectations, reliability/monitoring, security, logging), including for work done by external developers/partners
• Lead initiatives that enable scale, like reusable patterns/tooling (e.g., IDK) and frameworks that reduce one-off implementation work. You will be doing that primarily using Kotlin
• Improve ways of working: planning, prioritisation, and protecting the team from constant mid-week churn
• Collaborate with cross-functional teams to develop innovative solutions across Platform, Services, SMB, and other domains
• Participate in code reviews, post-mortems, and provide mentorship to other engineers
• Proactively address technical debt and guide the team through technical challenges and migrations
