Key Responsibilities:

Architecture & Design
- Define and evolve system architecture for cloud-native, microservices/event-driven platforms (scalability, resilience, security, cost).
- Create high-level and low-level designs, integration patterns, API contracts, and reference implementations.
- Lead design reviews; ensure alignment with domain-driven design (DDD), 12‑factor principles, and organization standards.
Engineering Leadership
- Lead squads through full SDLC - from discovery and PoCs to production and SRE handoff.
- Establish coding standards, code review practices, and secure-by-default patterns.
- Mentor and coach senior engineers; support career growth and succession of technical leaders.
Hands-on Development
- Build core services using Java (17+), Spring Boot, REST/GraphQL, and message/event streaming.
- Optimize for performance, concurrency, observability, and operational excellence (SLOs, error budgets).
- Drive quality with unit/integration/contract testing, test data strategy, and automated quality gates.
Cloud & Platform
- Design for AWS/Azure/GCP, container orchestration (Kubernetes), service mesh, and CI/CD.
- Implement infrastructure-as-code (IaC) patterns and secrets management.
- Partner with SRE/Platform teams on monitoring, alerting, logging, tracing, and cost governance.
Data & Integration
- Architect integrations across SQL/NoSQL, caching (Redis), and event streams (Kafka/Pulsar).
- Define data contracts, schema evolution strategies, and idempotent/eventual consistency patterns.
Security & Compliance
- Embed AppSec best practices, OWASP controls, secure API/auth (OAuth2/OIDC), and zero trust patterns.
- Ensure compliance with regulatory and audit requirements where applicable.
Stakeholder Partnership
- Translate business needs into technical roadmaps and architecture runway.
- Communicate trade-offs and decisions to both technical and non-technical audiences.
GenAI : Knowledge of MCP, A2A, Agentic Architecture

Required Qualifications:

5+ years of progressive experience building enterprise systems, with 5+ years in Java and Spring at scale.

- Caching (Redis), CI/CD (GitHub Actions/Azure DevOps/Jenkins), IaC (Terraform/ARM)
- Observability (OpenTelemetry, Prometheus/Grafana, ELK), feature flags/progressive delivery
Solid grasp of concurrency, performance tuning, resiliency patterns (circuit breakers, retries, bulkheads), and fault-tolerance.
Demonstrated leadership of architectural forums, design reviews, and mentorship.
Strong communication and stakeholder management skills.

Nice-to-Have:

Domain knowledge: Payments, banking, capital markets, insurance, e-commerce, supply chain, or telecom.
Security: Threat modeling, shift-left security, SAST/DAST, secrets rotation, mTLS.
Data: CDC (Debezium), schema registry, exactly-once semantics, streaming ETL.
