Role Summary
We’re seeking a seasoned Senior Java Developer Solution Architect with 6+ years of experience to lead end-to-end technical design and delivery of mission‑critical systems. You will own architecture decisions, drive engineering excellence, mentor senior engineers, and partner with product, security, and platform teams to build scalable, reliable, and secure distributed systems.
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.
