Technical Team Lead – .NET & Azure Integrations This role is a hands-on technical leadership role—owning delivery, guiding design, and leading engineers—not a traditional project manager and not a high-level enterprise architect.
Role Summary
We're seeking a Technical Team Lead, owning delivery on several high-impact initiatives. You will lead application integrations and SaaS migrations (legacy on‐prem to vendor-hosted solutions), coordinate across engineering and vendors, and technically direct a small group of developers to design and deliver robust, well‐operated solutions.
This role is ideal for a senior .NET developer or tech lead who has stepped into leadership/delivery and can drive design discussions, challenge approaches, assess upstream/downstream impacts, and remove blockers—while staying close enough to the code and data to make sound technical decisions.
What You'll Own
Leadership
Take ownership of assigned projects end-to-end: scope, design facilitation, execution, risk/issue management, cutover, and stabilization.
Provide day-to-day technical direction to developers; coordinate with infrastructure and data teams as needed.
Lead migration of legacy on-prem apps to vendor-hosted SaaS (multiple vendors) with bi-directional data flows that continue to support downstream systems.
Define and validate integration contracts (API specs, payloads, auth); oversee data mapping, reconciliation, and error handling.
Partner with vendors on environments, SLAs, change control, and test/cutover planning.
Solution Design & Review
Drive solution-level software design (not infra) for .NET/Azure apps and integrations; call out risks, tradeoffs, and non-functional needs (reliability, performance, observability).
Facilitate design reviews and sign-offs; ensure designs align to standards and are implementable by the team.
Data & Performance
Oversee Oracle database usage patterns; guide the tuning of complex stored procedures (execution plans, indexing, stats, refactoring).
Ensure data quality/reconciliation across systems during migrations and steady state.
Cloud & Platform
Leverage Azure services and best practices for integrations (e.g., Event Hubs, Functions, App Services, Key Vault, App Insights).
Ensure CI/CD readiness (Azure DevOps/Git) and release reliability, support monitoring and alerting strategy.
Stakeholder & Vendor Management
Engage business stakeholders on priorities and acceptance criteria; manage scope and expectations.
Serve as primary technical point of contact with third‐party vendors for integration design, testing, and production support handoff.
Operational Readiness
Ensure robust logging/telemetry, support runbooks, and on-call readiness as projects transition to production.
Drive post‐launch stability metrics and remediation.
Key Projects You'll Step Into
Three major SaaS replacements/migrations primarily integration-focused.
Ongoing stream of smaller one-off requests/tools while large migrations progress.
Required Qualifications
5+ years in application development/engineering with .NET (C#) across .NET Framework (4.5+) and modern .NET (Core/5/6/7/8+).
3+ years in a technical lead/delivery capacity (guiding developers, owning delivery outcomes, design facilitation).
Deep experience with application & data integrations: REST APIs, JSON, authentication/authorization (OAuth 2.0, client credentials), message/event patterns, retries and idempotency, error handling.
Experience leading on‐prem → SaaS or vendor-to-vendor migrations at scale.
Familiarity with monolithic systems and pragmatic modernization; understanding of microservices/event-driven concepts to inform tradeoffs (no microservices required now).
Reporting Line: Partners closely with the Engineering Manager
Team Mode: No direct reports initially; you will lead through influence, directing the work of a small group of developers and coordinating with infra/data SMEs.
Ownership: You will be assigned projects where you are accountable for delivery—from design through production stabilization.
