Where you fit in

As a Lead Engineer, you are a senior individual contributor within a cross-functional squad, reporting to a Team Lead. You play a key role in shaping and delivering high-quality Java-based solutions, translating architectural direction into robust, scalable implementations. You work closely with Architecture and Principal Engineers to ensure alignment with target architecture, standards, and operational constraints, while mentoring other engineers and raising overall team capability.

The impact you will have

Design, implement, and maintain backend services and APIs primarily in Java, following strong engineering and quality practices.
Own complex technical work end-to-end, from design and implementation through testing, deployment readiness, and production validation.
Drive high-quality code practices including code reviews, refactoring, performance tuning, and proactive technical debt management.
Collaborate with Architects and Principal Engineers to align on technical direction, reference architectures, and platform standards.
Translate architectural guidance into executable team-level designs, including service boundaries, integration patterns, transactional consistency, and data-access strategies.
Design systems with a strong focus on data correctness and integrity, including transactional databases, schema evolution, indexing, and query performance.
Handle concurrency, consistency models, idempotency, and failure scenarios, ensuring safe migrations and backward-compatible changes.
Embed quality and reliability by working closely with QA on appropriate testing strategies aligned to service criticality.
Partner with Performance Engineers and IT Operations to ensure operational readiness, including monitoring, alerting, dashboards, runbooks, and production access patterns.
Participate in incident response where required, contributing to root cause analysis, preventative fixes, and resilience improvements.
Support release readiness by collaborating with IT Operations on deployment constraints, rollback strategies, and production validation.
Mentor and coach engineers through pairing, code reviews, design sessions, and technical leadership within the squad.

What we’re looking for

5+ years of professional software engineering experience, with significant hands-on backend and service development.
Strong expertise in Java and common ecosystem frameworks (e.g. Spring or similar), including build and test tooling.
Proven experience owning and operating production systems in transactional or distributed domains.
Strong SQL and transactional database fundamentals, including data modelling, migrations, and performance considerations.
Solid understanding of distributed systems concepts such as latency, resiliency patterns, observability, and production debugging.
Strong testing discipline and familiarity with CI/CD best practices.
Clear communication skills and the ability to work effectively with cross-functional teams.
Pragmatic, outcome-focused approach to technical decision-making, balancing trade-offs without over-engineering..
