• Implement observability solutions including logging, tracing, metrics, SLIs/SLOs, and dashboards.
• Ensure strong security and compliance aligned with banking standards (OAuth2/OIDC, TLS, MAS TRM, PCI-DSS, GDPR).
• Lead engineering teams (onshore/offshore), manage delivery plans, risks, and align with product roadmaps.
• Provide reliable estimates, delivery timelines, and stakeholder updates throughout the SDLC.
• Establish shift-left testing, TDD/BDD, contract tests, and test data strategies.
• Ensure robust UAT readiness, release documentation, and production runbooks.
• Drive root cause analysis (RCA), post‑incident reviews, and continuous improvement.

Qualifications

• Bachelors/Masters degree in Computer Science, Engineering, or related field.
• 8–12 years of total experience, with 3+ years as a Tech Lead in complex, distributed systems.
