Job summary

Luxoft in India seeks 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.

You will design microservices in Java, optimize PostgreSQL, and deploy on AWS with observability and secure practices. Strong Spring, Angular, and Docker skills are required, with 9+ years of backend experience.

Qualifications

• 9+ years backend experience with Java, including core APIs, collections, concurrency, and JVM internals.
• Strong Spring ecosystem expertise: Boot, Data, Security; Cloud knowledge is a plus.
• 5+ years of professional Angular experience.
• PostgreSQL expertise: indexing, query tuning, transactions and isolation levels.
• Hands-on AWS experience with production services and services like S3, RDS/Aurora, MSK/Kinesis.
• Strong REST/gRPC API design with versioning and backward compatibility.
• Production-grade observability with logs, metrics, tracing; OpenTelemetry/Prometheus/Grafana.
• GitHub Actions CI/CD and modern branching strategies (GitFlow/Trunk Based).
• GitHub Copilot or similar AI coding assistants used to boost productivity without reducing quality.
• Containerization with Docker and infrastructure as code (Terraform/CloudFormation).
• Secure coding practices per OWASP Top 10; ability to implement authz/authn and encryption.
• Excellent communication; ability to translate ambiguous requirements into technical plans.
• Experience with Capital Markets, trading, or financial analytics is a plus.

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 strong CI/CD practices (GitHub Actions) and leverage Copilot to accelerate delivery.
• Ensure reliability, scalability, and fault tolerance (circuit breakers, retries, idempotency, backpressure).
• Implement security and compliance controls (authz/authn, secrets, IAM policies, encryption).
• Own production operations: monitoring, troubleshooting, and performance tuning.
• Contribute to architecture decisions, code reviews, and engineering 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).
• 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.
• 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.
• Experience with Capital Markets, trading, market data, or financial analytics.

Nice-to-Have Skills Description

• 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).
