Job description

The candidate will have responsibilities across the following functions:

Architecture and Product Design:

• Own end-to-end architecture for high-throughput, low-latency services and user-facing apps; define APIs, data models, caching, partitioning/sharding, and event flows.
• Translate product requirements into architectural roadmaps and component designs (domain-driven design, microservices, API-first).
• Drive secure-by-default patterns(Zero-Trust, principle of least privilege) and privacy-first data design.

Full-Stack Engineering (Java-First):

• Build backend services in Java/Spring Boot; design REST/gRPC APIs, asynchronous pipelines, and distributed workflows.
• Contribute to front-end (React/Next or similar) and shared libraries; ensure cohesive UX with strong performance budgets and accessibility.
• Implement CI/CD pipelines and DevEx improvements(build speed, quality gates, developer tooling).

High-Frequency Transaction Systems:

• Design for throughput, concurrency, and fault-tolerance (bulkheads, circuit breakers, idempotency, retry/backoff, message ordering).
• Performance tune JVM, thread pools, GC, connection pools; establish SLOs and p95/p99 latency targets.
• Introduce event streaming, queues, and exactly-once/at-least-once semantics where applicable.

Security and Compliance:

• Champion IAM/CIAM/IGA patterns (OAuth2/OIDC, SAML), secrets management, KMS, and robust RBAC/ABAC.
• Partner with Security to embed threat modelling, secure coding, and automated security testing in the SDLC.

Reliability and Observability:

• Define SLO/SLI/SLA, golden signals, and error budgets; implement tracing/metrics/logging dashboards (ELK/Grafana/OpenTelemetry).
• Lead incident reviews, root-cause analysis, and resilience tests (chaos, failover, DR).

Leadership and Collaboration:

• Mentor senior engineers; review designs/PRs; raise engineering bar via patterns, documentation, and standards.
• Collaborate with Product on discovery, scoping, and MVP slicing; influence build-vs-buy and cost/perf trade-offs.

Requirements:

• 10+ years in software engineering with strong Java and Spring depth; proven full-stack delivery.
• Experience in designing/developing high-availability and high-scalability systems, preferably on the cloud.
• Experience in designing heavy transaction management systems with both db and streaming services like Kafka and other cloud event hubs.
• Experience in designing and executing DR planning and recovery.
• Experience in Blue/Green deployments and canary deployments is an added advantage.
• Demonstrated ownership of designing high-throughput, low-latency distributed systems in production ( millions of requests/events/day).
• Hands-on experience with microservices, API-first architectures, caching strategies, and transaction integrity (idempotency, dedup).
• Solid grasp of cloud-native design (AWS preferred), containers/K8s, CI/CD, and infrastructure reliability.
• Strong understanding of security for web and APIs(authentication, authorisation, secrets, data protection).
• Excellent system design skills and ability to influence architecture across teams.
• Background in BFSI, payments, or cybersecurity platforms preferred.
