Technical Lead

About the Role

The Technical Lead owns end-to-end delivery across the organization's modern and legacy enterprise technology stacks. The role is accountable for functional delivery and equally for non-functional requirements (NFRs): performance, scalability, availability, observability, security and maintainability. You will keep business-critical systems stable and secure, lead their evolution to modern architecture, and ensure every solution aligns with enterprise architecture standards set by the Technology Architecture Group (TAG).

Your duties would include:

Technical leadership

• Define architecture, standards and patterns for front end, back end, data and integrations across both stacks.

• Lead the modernization roadmap, such as legacy web frameworks to modern SPA frameworks, .NET Framework to modern .NET, and monolith to microservices. Use incremental approaches and plan for coexistence.

• Make build, buy, refactor or retire decisions, and track technical debt.

• Run design reviews, spikes and proofs of concept. Turn requirements into architecture plans, estimates and task breakdowns.

Non-functional requirements (NFR) ownership

• Elicit, define, prioritize and document NFRs with stakeholders at the start of every initiative: performance, scalability, availability/SLA, resilience, capacity, security, observability, supportability and compliance.

• Convert NFRs into measurable targets (SLOs, response-time and throughput thresholds) and acceptance criteria, and design for them from the start.

• Verify NFRs before release through load, stress, soak and resilience testing, and sign off against agreed targets.

• Own capacity planning, caching, query and API optimization, and bottleneck analysis.

• Track NFR debt and include it in backlog prioritization.

Observability and performance engineering

• Implement and govern monitoring, logging, tracing and APM using enterprise tooling (ELK stack, Dynatrace, Azure Application Insights).

• Define standard logging, correlation ID, health-check, alerting and dashboard practices across services.

• Perform proactive performance analysis, production incident triage and root-cause analysis using APM data.

• Plan and run load and performance testing (for example JMeter, k6, Azure Load Testing, or equivalent) and report results with recommendations.

DevSecOps and security

• Embed security into the pipeline: static analysis (SonarQube), software composition and dependency scanning (Nexus IQ / Sonatype), and GitHub Advanced Security (code scanning, secret scanning, Dependabot).

• Own the remediation lifecycle for findings, with prioritization, ownership and SLA-based closure. Prevent quality-gate bypass.

• Coordinate with IT Security on VAPT (vulnerability assessment and penetration testing): scope, environment readiness, fix and retest, and closure evidence.

• Apply OWASP, secure coding, secrets management and hardening practices. Apply OAuth2/OIDC, JWT and role-based access, including bridging legacy authentication to modern identity.

• Keep dependencies, packages and runtime versions current, and retire unsupported components.

Enterprise architecture alignment

• Align solution designs with TAG principles, reference architectures, approved technology standards and governance checkpoints.

• Prepare and present design documentation for architecture review, and secure approvals and exceptions where deviations are needed.

• Ensure reuse of shared frameworks, libraries and patterns, and avoid technology sprawl.

• Contribute to the enterprise technology roadmap and standards.

Hands-on delivery

• Write and review production code on both stacks, and debug complex issues in legacy code with limited tests or documentation.

• Own API contracts, database changes and integrations (REST, SOAP, messaging, batch and file interfaces).

• Drive CI/CD, release management and environment strategy for on-premises (IIS, Windows services) and containerized deployments.

Team and stakeholders

• Mentor engineers, including upskilling legacy-focused developers on modern technologies.

• Partner with Product, BA, QA, Architecture, Security, DBA, Infrastructure and vendor teams.

• Act as the escalation point for production incidents.
