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 .
