Role Description Our backend systems process millions of transactions, serve enterprise customers across industries, and must perform flawlessly under pressure. We are scaling fast — and the decisions made at the architecture level today will define how the platform operates for years. We are hiring a Lead Backend Engineer to own that responsibility. This is a technical leadership role with real weight. You will set the architectural direction for core backend services, resolve ambiguity in complex distributed systems, engage directly with Product and DevOps leadership as a peer, not a downstream implementer and be the person the team turns to when things go wrong in production. Your decisions will have a measurable impact on system reliability, engineering velocity, and the careers of the engineers you mentor. We are looking for an engineer who has operated at this level before — someone who understands that senior engineering skill and technical leadership are not the same thing, and who is ready to take on both with full ownership. Responsibilities - Own backend features end-to-end: requirements, design, implementation, testing, and production rollout - Produce technical design documents for assigned features; present and defend them in design reviews - Write production-quality Java and Spring Boot code that meets the team’s standards for performance, maintainability, and test coverage - Identify and address edge cases, failure modes, and scalability constraints at the design stage — not after the fact - Deliver features on schedule with a consistent track record of quality and low post-release defect rates - Build and maintain microservices with a focus on reliability, scalability, and clean service boundaries - Design and optimise interactions with PostgreSQL and MongoDB; write performant queries and schema migrations - Implement Kafka-based event-driven workflows: consume, produce, and handle failure scenarios correctly - Use Elasticsearch for search features; understand indexing, mapping, and query construction - Instrument services with appropriate logging, metrics, and alerting from day one - Participate in on-call rotations and respond to production incidents with urgency and structure - Conduct root cause analysis on incidents related to your features and drive preventive improvements - Proactively monitor system health; surface degradation or risk to the Lead Engineer before it becomes an incident - Contribute to operational runbooks, post-mortems, and reliability improvement initiatives - Conduct thorough, constructive code reviews for junior engineers; elevate review quality on the team - Mentor junior engineers on technical approach, debugging discipline, and engineering best practices - Collaborate closely with the Lead Engineer on architecture decisions; contribute well-reasoned technical opinions - Partner with QA, DevOps, and Product to ensure features are delivered with full operational readiness Qualifications - Bachelor’s degree in Computer Science, Engineering, or equivalent experience - 5+ years of experience building and maintaining backend systems in production environments - Strong proficiency in Java with hands-on experience in Spring Boot–based microservices - Solid understanding of data structures, algorithms, and backend problem solving - Strong experience with PostgreSQL or other relational databases in high-scale systems - Experience building and consuming RESTful APIs and working with asynchronous systems - Strong debugging and troubleshooting skills in live production systems - Good understanding of software engineering best practices, including testing, code reviews, CI/CD, and release management - Clear communication skills and ability to collaborate effectively within a team - Hands-on experience with Kafka or similar messaging/event-streaming platforms - Exposure to distributed systems, microservices architecture, and scaling strategies - Experience with Docker and Kubernetes in production environments - Cloud platform experience (AWS, Azure, or GCP) - Caching with Redis: cache-aside, TTL strategies, cache invalidation patterns - Resilience engineering: Circuit Breaker, Bulkhead, Retry, Rate Limiting patterns Great to have - Experience using Redis, Elasticsearch, and MongoDB in production systems - Exposure to SRE or platform engineering practices - Experience contributing to or leading engineering hiring processes Benefits - Professional growth in a dynamic, rapidly expanding, high-social-impact industry - An open-minded, collaborative culture made up of enthusiastic colleagues who are driven by the challenge of innovation towards profound impact on people and the planet - A truly multicultural experience: you will have the chance to work with and learn from people from different geographies, nationalities, and backgrounds - Structured, tailored learning and development programs that help you become a better leader, manager, and professional through the Sun King Center for Leadership
