Integration Tech Lead (.NET Api & Azure)

NTT DATA Romania SA•Sibiu, AR

About The Position

We are a distributed team of Microsoft‑focused specialists within NTT DATA Romania, turning the power of the Microsoft ecosystem into reliable, scalable and modern business solutions. Known as the Microsoft Technologies Competence Center, we co-create and accelerate projects across all industries, without being tied to a specific business unit. Our expertise covers end‑to-end delivery of enterprise platforms using .NET, C#, ASP.NET Core, Azure Services, Power Platform and Microsoft 365, with proven results in domains such as Automotive, Banking, Insurance, Healthcare, Manufacturing and the Public Sector. We are looking for a Senior Integration Developer / Integration Tech Lead to lead the design and delivery of Azure Integration Services-based solutions across multiple claims workstreams, shaping how workflow/case tooling connects to core systems and third parties. This is hands-on leadership: you will code, set standards, run design reviews, and prevent MVP shortcuts becoming permanent outages.

Requirements

Bachelor’s degree in Computer Science, Software Engineering or related field
Minimum 5 years of experience on a similar position is required
Deep experience building and leading delivery of .NET integration services on Azure (C#, ASP.NET Core, Azure Functions)
Strong hands-on expertise with APIM (design, governance, security, monitoring, lifecycle management)
Strong expertise with Logic Apps (orchestration design, maintainability, operational handling)
Proven experience with Service Bus, Event Grid, and Event Hubs, including operational concerns (replay, dedupe, ordering, schema evolution)
Strong API security experience (OAuth2/OIDC flows, token lifecycle, authorisation models, managed identity patterns, policy enforcement)
Strong troubleshooting and “keep it running” instincts using Azure monitoring and distributed tracing
Ability to lead through ambiguity, force decisions, and keep delivery moving without leaving a support crater behind

Responsibilities

Own end-to-end integration architecture across workstreams, using AIS patterns across APIM, Logic Apps, Functions, Service Bus, Event Grid, and Event Hubs.
Define and enforce API standards: contract-first (OpenAPI), versioning strategy, error model, security posture, and backwards compatibility discipline.
Provide technical leadership for APIM: productising APIs, policy design, OAuth2/OIDC enforcement, rate limiting, access segregation, and monitoring strategy.
Lead orchestration strategy using Logic Apps, including how/when to split orchestration vs business logic, and how to keep workflows maintainable.
Lead serverless integration design with Azure Functions (C# primary), including deployment patterns, scaling behaviour, and resilience.
Make and defend decisions on messaging vs eventing vs streaming: Service Bus for command/message workflows; Event Grid for event distribution and event-driven integration; Event Hubs for high-throughput streaming scenarios.
Drive secure integration architecture using Entra ID (Azure AD), Managed Identities, APIM policies, and least-privilege access models.
Own observability and operability: standards for correlation IDs, tracing, dashboards, alerting, and incident readiness using Azure Monitor, App Insights, and Log Analytics.
Ensure secure connectivity patterns: VNET integration, private endpoints, firewalls, and route control for services that should not be internet-exposed.
Coach and raise the bar: code reviews, design reviews, and practical guidance for mid-level developers.
