.NET Technical Lead

About the Project
Join our ambitious effort to revolutionize battery recycling with the Refurb Battery MES 2.0 system. This is a modern, microservice-based system developed on Azure Kubernetes Services (AKS) using Dapr actors, Minimal APIs (.NET), and Vue.js for front-end. The MES platform integrates real-time hardware like barcode scanners, smart scales, and thermal/OAK-D cameras to automate and streamline lithium-ion battery sorting and repurposing.
We are looking for a hands-on .NET Technical Lead to take architectural ownership, mentor a small
engineering team, and ensure smooth technical execution across backend and infrastructure.

What You Will Do
Technical Leadership

• Own and evolve system architecture, ensuring modularity, scalability, and clean separation of concerns
• (Domain vs DTO, actor isolation).
• Design and implement backend services using Minimal APIs, Entity Framework Core, and Dapr actors.
• Drive architectural documentation (e.g., HLD, component diagrams, README for Helm/Bicep).
• Review and refactor existing codebases, enforce formatting and testability.
• Create and maintain architecture validation tests (e.g., NetArchTest rules).

Product Owner Support

• Work closely with the client (Product Owner) to gather, clarify, and refine requirements
• Translate business needs into technical tasks and ensure alignment with the team
• Help prioritize backlog items and suggest trade-offs between scope, time, and resources
• Support user story writing, acceptance criteria definition, and release planning
• Act as the main point of contact between the business side and development team
• Support testing, participate in UAT, and ensure that delivered functionality meets business goals

DevOps & Infrastructure Oversight

• Collaborate on Helm charts and Azure Bicep IaC scripts.
• Set up and maintain CI/CD pipelines for code and infrastructure deployments.
• Monitor application health using Prometheus and Grafana, and expand alerting rules.
• Ensure services are ready for production (HPA, secrets management, autoscaling).

Testing and Code Quality

• Define unit and integration testing strategies.
• Establish test coverage metrics and integrate them into CI pipelines.
• Ensure actor logic is covered by unit tests.
• Support E2E and mock-based frontend testing.

Stakeholder & Product Collaboration

• Work closely with the Product Owner and domain experts to understand user workflows.
• Translate business requirements into technical tasks and user stories.
• Help prioritize backlog and clarify acceptance criteria.
• Participate in UAT and validate that features meet stakeholder goals.

What We’re Looking For

• 6+ years of professional experience with .NET (C#)
• Strong experience in:
  • Dapr actors and service-to-service messaging
  • .NET 6+/Minimal APIs
  • Entity Framework Core + PostgreSQL
  • Azure Cloud + Kubernetes + Helm
  • DevOps practices (CI/CD pipelines, IaC)
• Solid understanding of distributed system design and system observability
• Experience with modular monorepo or multi-service structuring
• Familiar with frontend/backend API integration and micro-frontend architecture (Vue.js familiarity is a bonus)
• Strong testing culture (unit, integration, E2E)
• Excellent English communication skills, both written and verbal

Nice to Have

• Experience with hardware interaction (e.g., USB/COM peripherals, smart scales, cameras)
• Familiarity with Python for scripting/test automation
• Awareness of secure development practices and zero trust principles
• Knowledge of Octopus Deploy or similar for environment-specific service provisioning

What You’ll Get

• Private health insurance
• Gym/sports subscription reimbursement
• Education budget (certifications, courses, hardware)
• Weekly 1-hour self-development time (“5 PM Club”)
• Flexible working hours
