We're looking for a Senior Java Developer to design, build, and scale backend services for a high throughput, low latency platform with strict reliability and auditability requirements. You'll own end to end delivery—from design to production—collaborating closely with Product, QA, and DevOps.

Responsibilities

Design and implement microservices and event-driven components in Java (preferably Java 17+).

Model and optimize PostgreSQL schemas, queries, and transactions for performance and integrity.

Build resilient, observable services on AWS (ECS/EKS/Lambda, S3, RDS/Aurora, MSK/Kinesis, IAM).

Ship with strong CI/CD practices (GitHub Actions) and leverage GitHub Copilot to accelerate high quality delivery.

Ensure reliability, scalability, and fault tolerance (circuit breakers, retries, idempotency, backpressure).

Implement security and compliance controls (authz/authn, secrets, IAM policies, encryption at rest/in transit).

Own production operations: monitoring, troubleshooting, and performance tuning.

Contribute to architecture decisions, code reviews, and engineering standards.

Skills

Must have

9+ years of professional backend experience with Java (Core Java, Collections/Concurrency, Streams, JVM internals).

Strong with Spring ecosystem (Spring Boot, Spring Data, Spring Security; understanding of Spring Cloud is a plus).

Proven expertise with PostgreSQL: indexing strategies, query tuning (EXPLAIN/ANALYZE), transactions/locking, isolation levels.

Hands on AWS experience: deploying and operating production services (at least 3 of ECS/EKS/Lambda, RDS/Aurora, S3, SQS/SNS/MSK/Kinesis, CloudWatch, IAM).

Solid API design (REST/gRPC), versioning, pagination, and backward compatibility.

Production grade observability (logs, metrics, tracing; OpenTelemetry, Prometheus/Grafana, or similar).

CI/CD with GitHub and GitHub Actions (branching strategies, code reviews, trunk based or GitFlow).

Practical use of GitHub Copilot (or similar AI coding assistants) to boost productivity while maintaining code quality.

Experience building fault tolerant distributed systems (circuit breakers, bulkheads, rate limiting; resilience patterns).

Proficiency with containerization (Docker) and infrastructure as code (Terraform/CloudFormation—at least one).

Strong understanding of secure coding practices and common vulns (OWASP Top 10).

Excellent communication; ability to turn ambiguous requirements into actionable technical plans.

Nice to have

Experience with Capital Markets, trading, market data, or financial analytics.

5+ years of professional experience with Angular

Event streaming & messaging: Kafka, MSK, Kinesis, RabbitMQ.

Data modeling for auditable workflows, SLAs, and multi party approval processes.

Experience with multi tenant architectures and row level security.

Knowledge of domain-driven design (DDD) and CQRS patterns.

Experience with performance profiling (JFR, async-profiler) and JVM tuning (GC, heap, thread pools).

Exposure to Python and https://jobeax.com/link/JSd7UYCSg572jJDY for tooling and automation.

Familiarity with feature flags (e.g., LaunchDarkly) and blue/green or canary deployments.

Compliance/controls mindset (audit trails, data lineage, segregation of duties).
