- Partner cross-functionally with Mobile, Web/Frontend, Product Management, and UX to deliver seamless end-to-end features.
- Drive high standards of code quality, observability, test automation (unit, integration, and contract tests), and operational excellence.
- Mentor team members, participate in technical design reviews, and leverage modern AI development workflows to accelerate velocity and code quality.
Do you have the right ingredients*? (Requirements)
- 5+ years of software engineering experience building scalable, distributed backend microservices in production.
- Deep proficiency in Java or Kotlin, relational and NoSQL databases (e.g., PostgreSQL, DynamoDB), and event-driven architectures (Pulsar / Kafka / AWS).
- Proven experience designing clean, versioned REST / GraphQL APIs and handling asynchronous workflows at scale.
- Experience integrating payment workflows (e.g., card tokenization, pre-auth, Stripe/Adyen/payment gateway integrations) or compliance-sensitive systems.
- Strong focus on software reliability, schema design, latency optimization, and distributed systems resilience.
- Passion for collaborating across distributed global time zones with a single-threaded ownership mindset.
