- Design and implement long-running business processes using orchestration frameworks such as Temporal, Cadence, Camunda, or equivalent platforms.
- Apply distributed-systems principles to address reliability, idempotency, retries, timeouts, compensating transactions, eventual consistency, failure recovery, and data consistency.
- Design and implement Saga patterns, including orchestration-based and choreography-based approaches, for multi-service business transactions.
- Lead architecture discovery sessions, technical workshops, solution presentations, and design reviews with overseas clients and internal stakeholders.
- Translate business requirements into clear solution architectures, implementation plans, technical specifications, estimates, and delivery milestones.
- Drive multiple concurrent technical streams, identify dependencies and risks early, and maintain delivery quality under changing priorities.
- Establish engineering standards for workflow design, API contracts, error handling, versioning, testing, deployment, observability, and operational readiness.
- Use AI-assisted SDLC practices responsibly to improve developer productivity, code quality, test coverage, documentation, and delivery velocity.
- Design and contribute to agentic orchestration solutions, including coordination of AI agents, tool/API integrations, workflow state management, guardrails, human-in-the-loop controls, and evaluation approaches where relevant.
- Perform hands-on development of critical components, prototypes, integrations, and reference implementations.
- Conduct code reviews and architectural reviews, ensuring solutions are maintainable, performant, secure, and aligned with engineering best practices.
- Mentor and guide junior developers; support technical growth through pairing, reviews, reusable patterns, technical sessions, and constructive feedback.
- Collaborate with delivery, product, platform, QA, DevOps, security, and client teams to ensure successful implementation and production adoption.
- Contribute reusable assets, accelerators, templates, documentation, and best practices to the Temporal Capability Center.
