You shape and execute technical direction in close collaboration with Architecture and Principal Engineers, ensuring the team’s implementation aligns with agreed standards, target architecture, and operational constraints. **The impact you will have:** **Hands\-on engineering \& delivery (primary)** * Design, implement, and maintain backend services and APIs primarily in Java (and relevant frameworks) with strong engineering discipline. * Own complex technical work end\-to\-end: implementation, testing, deployment readiness, and production validation. * Drive high\-quality code practices: reviews, refactoring, performance tuning, and technical debt management. **Technical leadership in partnership** * Collaborate with Architects and Principal Engineers to align on technical direction, reference architectures, and platform standards. * Translate architectural direction into executable team\-level designs: service boundaries, integration patterns, transactional consistency, and data\-access strategy. * Lead technical discovery/spikes and propose pragmatic options with trade\-offs. **Transactional systems \& data engineering** * Design for correctness and integrity using transactional databases (SQL, schema evolution, indexing, query performance). * Handle concurrency, consistency models, idempotency, and failure modes (retries, sagas/outbox patterns where applicable). * Ensure safe migrations and backward\-compatible changes to data structures and service contracts. **Mentorship \& team enablement** * Mentor engineers through pairing, code reviews, design sessions, and technical coaching. * Raise team capability in Java engineering practices, distributed systems thinking, and operational hygiene. **Quality, reliability, and operability (“build it, run it”)** * Embed robust testing aligned to service criticality working closely with Quality Assurance Engineers. * Partner with Performance Engineers and IT Operations to ensure operational readiness: monitoring, alerting, dashboards, runbooks, and production access patterns. * Participate in incident response as needed; work with the incident team on follow\-ups (RCA actions, preventative fixes, resilience improvements). **What we’re looking for:** We are looking for a **Technical Leader with solid experience in Java** and related technologies. * Degree in Computer Science or equivalent field. * Professional software engineering experience, with substantial hands\-on backend/service work. * Strong Java expertise and common ecosystem frameworks (e.g., Spring / similar) and build/test tooling. * Strong SQL and transactional DB fundamentals (modeling, migrations, performance, locking/concurrency implications). * Distributed systems fundamentals: latency, resiliency patterns, observability, and debugging in production. * Strong testing discipline; familiarity with CI/CD best practices. * Demonstrable ownership of production systems in a transactional domain. * Advanced English. * Clear communication and alignment skills across Architecture, Principal Engineers, Product, QA, NOC, and IT Ops.
