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 OwnLeadershipTake 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.Track work (lightweight PM rigor): delivery plan, backlog, RAID log, metrics, stakeholder updates.SaaS Migrations & IntegrationsLead 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 & ReviewDrive 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 & PerformanceOversee 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 & PlatformLeverage 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 ManagementEngage 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 ReadinessEnsure 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 IntoThree major SaaS replacements/migrations primarily integration-focused.Ongoing stream of smaller one-off requests/tools while large migrations progress.Required Qualifications5+ 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).Strong Azure knowledge (conceptual to practical) for app/integration patterns—e.g., Event Hubs (or event streaming concepts), Functions, App Services, Key Vault, App Insights.Deep experience with application & data integrations: REST APIs, JSON, authentication/authorization (OAuth 2.0, client credentials), message/event patterns, retries and idempotency, error handling.Oracle database proficiency: SQL/PLSQL, query and stored procedure performance tuning, reading execution plans, indexing strategies.Proven ability to translate business needs into technical designs, assess upstream/downstream impacts, and challenge approaches with sound reasoning.Comfortable with SDLC leadership in Agile/Kanban environments; tools such as Azure DevOps, Git, or Jira.Excellent soft skills: collaborative leadership, structured communication, vendor management, and stakeholder alignment.Nice to HaveExperience 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).Observability and ops maturity: App Insights, dashboards, alerting, runbooks, SLO/SLA thinking.ETL/data sync patterns; data quality/reconciliation strategies.Experience with API documentation and tooling (Swagger/OpenAPI, Postman).Tooling familiarity: Oracle SQL Developer/TOAD, Splunk/Kibana (or similar), Confluence/Wiki.How You'll WorkReporting Line: Partners closely with the Engineering ManagerTeam 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.Tech Stack SnapshotLanguages/Frameworks : C#, .NET Framework 4.5+, .NET (Core/5/6/7/8+)Cloud : Microsoft Azure (Event Hubs, Functions, App Services, Key Vault, App Insights)Data : Oracle (SQL/PLSQL, performance tuning, stored procedures), possibly SQL Server exposureIntegrations : REST APIs, JSON, OAuth 2.0, webhooks, message/event patternsDevOps/SDLC : Azure DevOps, Git, CI/CD, Agile/KanbanTooling : Postman, Swagger/OpenAPI, Oracle SQL Developer/TOAD
