Luxoft India; Dadri; On-site; INR 1,500,000 - 3,500,000; Full time

Job summary

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

In this role, you will design microservices in Java 17+, optimize PostgreSQL schemas, and build observable services on AWS.

Qualifications

• 9+ years backend Java experience (Core Java, concurrency, Streams, JVM internals).
• Spring Boot/Data/Security; Spring Cloud is a plus.
• PostgreSQL: indexing, query tuning, transactions/locking, isolation levels.
• AWS: deploy/operate prod services (≥3 of ECS/EKS/Lambda, RDS/Aurora, S3, SQS/SNS/MSK/Kinesis, CloudWatch).
• REST/gRPC APIs: design, versioning, pagination, compatibility.
• Observability: logs, metrics, tracing (OpenTelemetry, Prometheus, Grafana).
• CI/CD with GitHub Actions: branching, code reviews, trunk/GitFlow.
• GitHub Copilot usage with care to maintain quality.
• Docker containerization and IaC (Terraform/CloudFormation).
• Secure coding and OWASP Top 10 awareness.
• Clear communication; translate ambiguous requirements into plans.

Responsibilities

• Design and implement microservices and event-driven components in Java (Java 17+).
• Model and optimize PostgreSQL schemas, queries, and transactions.
• Build observable services on AWS (ECS/EKS/Lambda, RDS/Aurora, S3, MSK/Kinesis, IAM).
• Enable CI/CD with GitHub Actions and leverage GitHub Copilot for productivity.
• Ensure reliability, scalability, and fault tolerance (circuit breakers, retries).
• Implement security controls (authz/authn, secrets, IAM, encryption).
• Own production operations: monitoring, troubleshooting, performance tuning.
• Contribute to architecture decisions, code reviews, and standards.

Job 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.

Mandatory Skills Description:

• 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.
• 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 Skills Description:

• Experience with Capital Markets, trading, market data, or financial analytics.
• 5+ years of professional experience with Angular
• 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).
