YOUR NEW ROLE
This role is for CODE LEAP's client company - JTL-Software
JTL-Software is one of Germany's leading providers of e-commerce and ERP solutions. More than 50,000 retailers rely on JTL every day to run their business. Our global development center in Vietnam is looking for talented people to build the next generation of these products. You'll work in an international team that pairs German software quality and Vietnamese speed to innovate.
As Hands-On Engineering Manager / Tech Lead, you own the technical direction of the cross-functional team that owns two core platform areas: Managed ERP Hosting and the Documents Archive Solution. Together with your backend, frontend/fullstack, and
DevOps engineers you drive our transformation towards modular architectures, modern APIs, and cloud-ready services. You ensure architectural integrity, mentor the team, drive engineering excellence - and still write production code yourself.
The team owns two core platform areas. Managed ERP Hosting is the on-demand provisioning and reliable operation of per-tenant ERP environments on Azure - a wizard-driven, message-based onboarding flow (Azure Service Bus with a provisioning orchestrator, secrets handled via Key Vault references) that today spins up Windows VMs with SQL Server and the Wawi tool chain, and is moving step by step towards Linux and Docker.
The Documents Archive
Solution (DAS) is JTL's GoBD-compliant archive for invoices and business documents: a greenfield service built as a React SPA plus a TypeScript backend (Bun / Effect) on Azure - with PostgreSQL, georedundant Blob storage, and an event-driven integration (CloudEvents) into the JTL Hub and the Managed ERP Panel.
This is a genuinely cross-stack team, so you are comfortable leading and contributing across both a .NET world and a modern TypeScript world.
You are the bridge between product, engineering, and stakeholders: you turn the Product Manager's requirements into a clear, well-estimated plan and make sure the team delivers against it reliably.
At JTL, AI-assisted development is not a nice extra - it is a core part of how we work. Our engineers use tools like GitHub Copilot, Claude Code, ChatGPT, and similar AI assistants every day. We expect you to either bring hands-on experience with these tools or demonstrate a clear, verifiable willingness to actively use them.
YOUR EXCITING TASKS
You discuss the Product Manager's requirements with the team and break them down into epics and Jira tasks the team can execute against.
You facilitate estimations together with the team and capture them on the corresponding Jira items.
You own the plan: you track progress, ensure the team stays on plan, and keep it continuously up to date in Jira.
Technical leadership and mentoring of the engineering team - guiding architectural decisions, code reviews, and best practices.
Personnel responsibility: regular 1:1s, performance conversations, goal setting, and supporting personal development plans.
Ownership of team delivery: sprint planning, backlog refinement, removing blockers, and ensuring reliable execution.
Acting as the primary point of contact for Product Management, Release Management, and stakeholders on technical matters.
Recruitment support: interviewing candidates and helping build out the engineering team.
Fostering a culture of quality, security, and continuous improvement within the team.
Technical Responsibilities (hands-on)
Active development and code ownership across the stack - C#/.NET services and React/TypeScript frontends.
Owning the technical direction of Managed ERP Hosting - the wizard-driven, message-based (Azure Service Bus) provisioning and reliable operation of per-tenant ERP environments on Azure.
Owning the Documents Archive Solution (DAS) - JTL's GoBD-compliant archive for invoices and business documents, built as a React + TypeScript (Bun / Effect) service on Azure (PostgreSQL, Blob storage, Event Hub) and integrated into the Hub and Managed ERP Panel.
Defining and evolving the technical architecture: modular design, REST and GraphQL APIs, cloud infrastructure (Azure), and data flows.
Driving the roadmap for the cloud transformation - moving the ERP step by step from virtual machines onto Linux and Docker.
Owning the roadmap for test automation, CI/CD pipelines (GitHub Actions), observability, and operational reliability.
Evaluating and adopting AI-assisted development tools (GitHub Copilot, Claude Code, Cursor) to accelerate team productivity.
Championing secure-by-design practices and maintainable, high-quality code across the entire stack.
Hands-on incident response and on-call escalation support together with the team.
