Senior software Engineer – Cloud‑Native Microservices

We’re looking for a hands‑on, expert‑level Java engineer to build and evolve cloud‑native microservices that power mission‑critical platforms. You will work closely with Solution & Technical Architects, Developer Leads, and partner teams to design, implement, and ship resilient services at scale.

This is a code‑first leadership role: you will own complex services end‑to‑end, raise engineering quality bars, and mentor others on modern distributed systems practices.

What You’ll Do (Key Responsibilities)

Architecture & Design

• Design and implement microservices in Java (preferably Spring Boot / Spring Cloud) with clean architecture, domain‑driven design (DDD), and well‑bounded contexts.
• Model APIs and events using OpenAPI/Swagger and AsyncAPI; define idempotent, versioned contracts and backward‑compatible schema evolution.
• Build event‑driven flows using Kafka/Pulsar (streams, outbox, replay, exactly‑once/at‑least‑once semantics) and transactional messaging patterns.
• Apply resiliency patterns (circuit breakers, timeouts, retries, bulkheads) and performance‑oriented design (threading, async/non‑blocking IO with Virtual Threads / CompletableFuture, connection pooling, profiling).

Implementation & Quality

• Write high‑quality Java code with strong unit, contract, integration, and performance tests (JUnit, AssertJ, Testcontainers, WireMock, Gatling, JMH).
• Ensure observability by design: distributed tracing (OpenTelemetry), structured logging (JSON), metrics (Micrometer/Prometheus), health checks, and golden signals.
• Champion secure coding (OWASP Top 10, secrets management, OAuth2/OIDC/JWT), data governance (PII masking, encryption at rest/in transit), and SAST/DAST gate compliance.

Cloud, Platform & Delivery

• Containerize services (Docker) and deploy to Kubernetes (Helm/Kustomize); optimize resources (HPA, liveness/readiness probes) and implement blue/green and canary rollouts.
• Automate CI/CD (GitHub Actions / Azure DevOps / Jenkins) using trunk‑based development, feature flags, and progressive delivery.
• Partner with Architects on non‑functional requirements (latency, throughput, availability, cost), perform load and chaos testing, and drive SLO/SLA adherence.

Legacy Modernization & Data Integration

• Work effectively with existing relational database constructs such as stored procedures, functions, sequences, triggers, and batch jobs.
• Assess legacy database‑centric or monolithic designs and drive migration to modern, microservices‑based architectures.
• Refactor or redesign stored‑procedure‑heavy logic into service‑based, domain‑aligned implementations, ensuring data consistency, performance, and backward compatibility.
• Define data migration and co‑existence strategies (dual‑writes, strangler pattern, phased decommissioning) during modernization initiatives.

Collaboration & Mentoring

• Work with Solution and Technical Architects during discovery and grooming; refine requirements into executable designs.
• Collaborate with vendor teams (e.g., Cybage) by reviewing designs and PRs, enforcing standards, and providing clear, constructive feedback.
• Mentor engineers on microservices design, concurrency, performance tuning, observability, testing discipline, and modernization best practices.

What You’ll Bring (Required Qualifications)

• 6-8+ years of professional software development experience; 4+ years building Java microservices in production.
• Deep expertise in Java 17+, Spring Boot/Spring Cloud, Gradle/Maven, REST/JSON; gRPC/Protobuf is a plus.
• Strong experience with Kafka (streams, schema registry – Avro/Protobuf, consumer groups, partitioning, rebalancing) and transactional data patterns (sagas, outbox).
• Solid understanding of distributed systems (consistency models, CAP, retries vs idempotency, back pressure, eventual consistency, caching).
• Proven experience with relational databases, including hands‑on knowledge of stored procedures, sequences, indexing strategies, and query optimization.
• Demonstrated ability to modernize legacy systems and data models into scalable, cloud‑native microservices.
• Production experience on Kubernetes and cloud platforms (AWS/Azure/GCP): networking, service mesh (Istio/Linkerd – bonus), secrets, IAM, and cost awareness.
• Strong testing discipline: unit, contract (Pact/AssertJ JSON), integration (Testcontainers), E2E, performance (Gatling/JMH), and CI automation.
• Observability expertise: OpenTelemetry, Micrometer, Prometheus, Grafana, ELK; ability to debug production issues using traces and high‑cardinality logs.
• Security experience: OAuth2/OIDC/JWT, TLS/mTLS, certificate rotation, vulnerability remediation, SAST/DAST familiarity.
• Ability to review architectural and vendor deliverables, identify gaps, and guide remediation.
• Experience with Vert.x and/or gRPC.

Nice to Have (Preferred)

• Knowledge of CQRS/Event Sourcing, workflow orchestration (Temporal/Cadence), or Debezium/CDC.
• Data stores: Postgres/MySQL, Redis, MongoDB/Cosmos/DocumentDB, Elasticsearch/OpenSearch.
• API gateways and service mesh capabilities (rate limiting, circuit breaking, authN/authZ).
• Prior experience with platform engineering, internal developer platforms, or Backstage.
