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

• Own the Product: Develop, prioritize and implement product roadmaps (typically 6-12 months) grounded in user insights, field learnings, stakeholder feedback, and business ROI. • Prioritize initiatives that deliver measurable impact—either revenue growth or cost reduction. • Influence senior leadership to evaluate, prioritize, and greenlight high impact product investments. • Make explicit prioritization trade-offs based on business impact, engineering capacity, and operational readiness. • Mentor and nurture different product team members by setting priorities, removing their blockers, implementing best PM practices/frameworks. • Set high standards for documentation, prioritization rigor, and execution discipline. • Work on the full product lifecycle: Discovery, design, development, GTM, and sustained go‑lives. • Drive requirements definition: PRDs, workflow diagrams, edge cases, functional and non-functional requirements. • Ensure on‑time, high‑quality releases within defined turnaround times (TATs). • Own release planning, rollout sequencing, and adoption tracking across countries and teams. • Ensure every launch has clear success metrics, operational readiness, and rollback plans. • Partner daily with engineering teams to shape system design, APIs, and data models. • Head sprint planning, backlog grooming, and scope control. • Define testing strategy focused on business-critical flows, failure modes, and realistic user behaviour. • Use SQL and dashboards to validate product usage, data quality, and business impact post-launch. • Work on discovery efforts to identify issues in existing processes, user pain points, and competitive threats. Identify root causes behind process breakdowns, revenue leakage, fraud risk, or poor customer experience. • Translate observations into concrete problem statements, not abstract “user needs”. • Push back on solutions that look good on paper but won’t work at scale in the field. • Collaborate and act as the single-threaded owner across Engineering, Operations, Sales, Risk, Programs, Call center, Data etc. • Work on aligning scope, timelines, rollout plans, and success metrics. • Escalate decisively when trade-offs are required between speed, quality, and scope. • Define and track key performance indicators (KPIs) to measure product success and impact. • Use data to iterate on product performance and drive growth. • Travel about 10%-20% of the time to places including but not limited to India, Kenya, Myanmar, Mozambique, Nigeria, Tanzania, Togo, Uganda, Zambia and to any other Sun King markets.
