Lead Developer (m/f/d) / Team Lead (m/f/d) Software Development (Backend / Frontend / Full-Stack)

LEAD DEVELOPER (M/F/D) / TEAM LEAD (M/F/D) SOFTWARE DEVELOPMENT BACKEND / FRONTEND / FULLSTACK

We at AraCom are looking for a new team member for our sister company Milestone Consult GmbH to fill the position of Lead Developer (m/f/d) / Team Lead (m/f/d) in Backend / Frontend / Full-Stack Software Development. You will be the technical anchor for the development of a state-of-the-art solution that is consistently built on the latest frameworks (.NET 10/Angular V21).
In this role, you act as a key translator: You analyze complex architectural blueprints, communicate them to the team, and ensure adherence to the highest standards within a stable system landscape. As a technical mentor and counterpart to the Product Owner and architects, you take true ownership of code quality, security, and maintainability. You provide technical guidance to your colleagues, share your knowledge during code reviews, and are eager to help the next generation of developers reach the next level. You are the driving force behind refinements and the technical backbone of daily operations—grounded in infrastructure but at the cutting edge of the tech stack.
We are looking for an experienced Lead Developer who combines technical excellence with strong leadership skills. In this role, you’ll serve as the bridge between our software architects’ vision and the team’s operational implementation. We rely on cutting-edge technologies in a stable environment—with us, you’ll be working with tomorrow’s tools today. Whether your focus is on backend, frontend, or full-stack development is up to you.

• Translator & Implementer: You don’t build castles in the air when it comes to architecture, but you are the one who translates existing blueprints into excellent code. You understand complex specifications and ensure they are implemented in a technically sound and maintainable way
• Team Driver: You guide the team through refinements and serve as the technical backbone in daily stand-ups. You identify obstacles before they become problems and ensure a smooth development process
• Mentor & Coach: You help the "next generation" of developers take their technical skills to the next level. Through constructive code reviews and active knowledge transfer, you foster your colleagues’ growth and ensure code quality
• Technical Counterpart: Together with the architect, you serve as the technical anchor for the Product Owner. You evaluate requirements, assess complexities, and take ownership of the security, scalability, and stability of our system

• Backend expertise: At least 5 years of experience with C# / .NET (starting with .NET 10) as well as in-depth knowledge of CQRS and MediatR
• Frontend expertise: At least 5 years of experience with Angular (v. 16+, starting with Angular 21) and TypeScript, including confident use of Signals and Observables
• Data & API: Deep understanding of Entity Framework, MS SQL Server, as well as REST / WebAPI and OpenAPI Spec
• Methodology & Tools: Proficient in dependency injection, Git, and ideally GitLab

• Architecture Communicator: You understand existing architectures, adhere to them, and can confidently communicate them to the team
• Technical Mentor: You enjoy helping the next generation of developers reach new heights through code reviews and knowledge sharing
• Sparring Partner: You serve as the technical counterpart to the Product Owner during refinements and provide support to the team during daily stand-ups
• Ownership: You proactively identify risks and obstacles and are responsible for code quality, security, maintainability, and scalability

Team & Spirit: Family-like, agile, and effective.
At Milestone, you’ll work in a team of around 75 specialists where a human-centered approach and flat hierarchies aren’t just empty phrases, but a way of life. We maintain the agility of a specialized firm while being part of a strong corporate group with over 500 colleagues.
This gives you a decisive advantage: You’ll work in a family-like environment with maximum creative freedom, yet for large projects, you’ll have the implementation power of a 500-person network behind you.

• Flexible working hours: To help you organize your day more flexibly, we offer a trust-based work schedule with core working hours
• 30+ days of vacation: With us, you get 30 days of vacation and 3 days off for traditional holidays per year
• Professional development: We support your growth in an exciting environment with a training and development program
• Company bike: Stay fit and do your part for the environment with a company bike
• Employee events: We host regular company and team events where you can have fun with your colleagues outside the office
• Company pension plan: Start planning for your retirement today
• Employee stock ownership
• Employee Discounts: Take advantage of exclusive employee discounts on many different brands
• Accessibility: You can access all floors of our offices in our newly built building without barriers
• Meal Allowance: You can get freshly cooked meals in our cafeteria at a discounted price
• Cafeteria: Our in-house chef treats us to discounted, freshly prepared meals
• Company Car: Starting at a certain position, you’ll receive a company car of your choice
• Health Initiatives: Because your health is important to us, we have a corporate health management program. We also have an in-house fitness studio. Once a week, we have an “active break” where a physical therapist leads us through targeted exercises for the office environment. Additionally, we offer nutritional counseling and much more
• Parking: Free parking spaces, including charging stations for electric vehicles, are available right in front of the office building
• Free drinks: To keep your ideas flowing, we provide free mineral water as well as hot beverages like coffee or tea
• Additional benefits: With us, you can lease hardware—even for personal use—at corporate rates

Why this role is exciting for you
We’re starting right away with .NET 10 and Angular V21. For you, this means: You’ll work in a technologically leading environment where you can fully leverage your expertise in C#, SQL Server, and modern frontend patterns (Signals & Observables). Since we are developing an on-premise solution, we retain full control over our stack—this requires deep technical understanding and offers room for real engineering work.
We look forward to getting to know you!
