Senior Software Developer III

Position: Senior Software Developer III 

Global Tax Network US, LLC (GTN) is seeking a full-time Senior Software Developer III in the Minneapolis/St. Paul and surrounding areas to build modern, cloud-native products on a distributed services architecture. At GTN, you’ll ship meaningful features in a pragmatic Agile cadence, own problems end-to-end, and collaborate with engineers who care about clean code and reliability.

Why developers like GTN:

• Summer 4x10s program available (four 10-hour days)
• 25 days of PTO plus paid holidays
• 401(k) with company match, competitive medical/dental/vision
• Ability to earn Spot Bonuses through achievements and excellent work

Who is GTN? We’re a mobility tax services firm that specializes in providing mobility tax services to corporate programs and individual clients, and our engineering team builds the internal and client-facing platform that powers it. This is product/platform engineering (not staff augmentation) with stable priorities and long-term ownership.

We build a modular platform for internal teams and clients (portals, workflow automation, documents, reporting, integrations) plus carefully scoped AI for internal productivity. Services are independently deployable, horizontally scalable, and shipped frequently via PR-based CI/CD.

We run pragmatic Agile with a strong code-quality bar. You’ll work in a small team (typically 3–4 developers) with high visibility and ownership from idea → production. No on-call rotation for this role; support happens during normal business hours.

Located in Minneapolis/St Paul and surrounding areas. Remote opportunities available with availability to meet in the Maple Grove headquarters as needed. Flexible schedule focused on outcomes. We collaborate primarily during Central Time business hours with a few shared core hours for meetings.

Leadership & engineering culture: engineer-led decisions with lightweight design discussions when needed, pragmatic tech-debt management, and protected focus time. Our Software Director is also an individual-contributor programmer.

What success looks like:

• Ramp up on our domain and platform, and ship your first production change(s) with confidence
• Own a service or feature area: improve reliability, performance, and developer experience (tests, tooling, CI/CD)
• Partner with your team and stakeholders to deliver an end-to-end feature and communicate tradeoffs early

What you’ll do:

• Design, build, and operate backend cloud services in a distributed microservices architecture, with occasional collaboration in the UI layer (Angular) to deliver end-to-end features
• Build and evolve REST APIs and backend services in .NET (C#), with a strong focus on reliability, observability, and performance
• Use modern tooling (including GitHub Copilot) responsibly to move faster without sacrificing quality
• Contribute to CI/CD, pull-request workflows, and release quality (experience with Azure DevOps is a plus)
• Write unit and integration tests and validate changes to ensure software quality
• Support and improve Azure services with solid logging/monitoring (App Insights / Azure Monitor) during business hours (no on-call)
• Take ownership: clarify ambiguity, propose pragmatic solutions, and communicate tradeoffs early
• Balance multiple priorities in a remote, distributed team environment

Tech we use:

• .NET / C#, WebAPI/Rest APIs, Entity Framework, SQL Server, NoSQL
• Angular / TypeScript (micro-frontend / componentized UI patterns)
• Azure for 100% cloud-native hosting and scaling
• CI/CD: PR-based workflow and pipelines (Azure DevOps)
• Distributed microservices
• Microsoft Fabric (a plus)

What we’re looking for:

MUST-HAVES:

• 10 years of experience in applicable technologies (e.g., .NET/C#, distributed systems, REST APIs, SQL, Angular highly preferred)
• Experience designing distributed systems (microservices, service boundaries, API versioning, resiliency)
• Comfortable with SQL and data modeling
• Comfortable using AI-assisted dev tools (e.g., GitHub Copilot) responsibly to accelerate development while maintaining quality
• Strong Git pull request habits, code review participation, and automated testing mindset
• Comfortable collaborating in a modern front-end (Angular/TypeScript or similar such as React) - you don’t need to be a UI specialist, but you should be able to contribute when needed

 Nice-to-haves:

• Azure DevOps (boards, repos, pipelines, release gates)
• Azure Infrastructure experience
• Microsoft Fabric / analytics engineering or Power BI ecosystem familiarity
