Senior backend Java Developer

Luxoft; Dadri; On-site; INR 2,500,000 - 5,000,000; Full time

Job summary

Luxoft is seeking a Senior Java Developer to design, build, and scale backend services for a high-throughput platform. You will own end-to-end delivery from design to production, collaborating with Product, QA, and DevOps.

The role requires strong Java backend experience (9+ years), Spring, AWS, PostgreSQL expertise, and solid API design with observability. Angular and Python exposure are welcome; candidates should drive reliability and security in a distributed system.

Qualifications

• 9+ years backend Java experience including Core Java, Collections/Concurrency, and JVM internals.
• Experience with Capital Markets, trading, market data, or financial analytics.
• Strong Spring ecosystem knowledge: Spring Boot, Spring Data, Spring Security; Spring Cloud a plus.
• 5+ years of professional Angular experience.
• Python for tooling/automation.
• Proven PostgreSQL expertise: indexing, query tuning, transactions, isolation levels.
• Hands-on AWS production experience (ECS/EKS/Lambda, RDS/Aurora, S3, MSK/Kinesis, IAM).
• Solid API design (REST/gRPC), versioning, pagination, backward compatibility.
• Observability: logs/metrics/tracing (OpenTelemetry/Prometheus/Grafana).
• CI/CD with GitHub and GitHub Actions; code reviews and trunk-based or GitFlow.
• GitHub Copilot to boost productivity while maintaining quality.
• Experience building fault-tolerant distributed systems (circuit breakers, bulkheads, rate limiting).
• Docker and IaC: Terraform or CloudFormation.
• Secure coding practices and OWASP Top 10 knowledge.
• Excellent communication; translate ambiguous requirements into actionable plans.

Responsibilities

• Design and implement microservices and event-driven components in Java (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 CI/CD practices (GitHub Actions) and leverage Copilot for faster delivery.
• Ensure reliability, scalability, and fault tolerance (circuit breakers, retries, idempotency).
• Implement security and compliance controls (authz/authn, secrets, IAM policies, encryption).
• Own production operations: monitoring, troubleshooting, performance tuning.
• Contribute to architecture decisions, code reviews, and engineering standards.

Job description

Project description

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).
• Experience with Capital Markets, trading, market data, or financial analytics.
• Strong with Spring ecosystem (Spring Boot, Spring Data, Spring Security; understanding of Spring Cloud is a plus).
• 5+ years of professional experience with Angular
• Exposure to Python for tooling and automation.
• 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

• 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 Node.js 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).
