Senior Manager of Software Development (f/m/d)

With over 4 million domains and more than 2 million customers, we, as an IONOS company, are among the largest web hosting providers worldwide. We operate two TÜV-certified data centers with over 70,000 servers. Our products are diverse and form the backbone of our success, but they only come to life through our amazing employees.

We are seeking a technically adept and strategically minded Senior Manager of Software Development to lead and support a high-performing engineering team. This role is ideal for a seasoned leader with a strong background in system-level development and a deep understanding of agile delivery processes. You will play a critical role in aligning engineering output with product vision while fostering a culture of technical excellence and autonomy.

As a Senior Manager, you’ll provide direction, remove roadblocks, and mentor a team of experienced developers working with languages such as C, Rust, and Go.

Tasks

• Lead, mentor, and inspire a team of software developers working on system-level and performance-critical software components.
• Design, implement, and continuously improve agile workflows and ticketing systems (e.g., Jira) to align engineering efforts with product goals while ensuring visibility and delivery focus.
• Collaborate closely with Product Management to refine priorities, manage scope, and translate business objectives into actionable engineering work.
• Oversee technical execution across key areas such as OS-level development, high-performance computing, and low-level systems work.
• Support and champion best practices in debugging, profiling, and performance tuning while avoiding top-down micromanagement.
• Cultivate a high-trust, feedback-driven culture where individual contributors can grow and thrive.

Qualifications

• 5+ years of experience leading high-performing software development teams in fast-paced, agile environments.
• Technical foundation with working knowledge of system-level programming languages such as C, Rust, and Go.
• Solid understanding of operating system internals, device drivers, and performance optimization techniques.
• Deep expertise in agile methodologies, including sprint planning, backlog grooming, and iterative delivery across multiple teams.
• Proven ability to communicate effectively with both engineering and non-engineering stakeholders—bridging the gap between technical detail and strategic goals.
• Experience managing or supporting self-organizing, autonomous teams with a focus on craftsmanship and responsibility.

Benefits

• Hybrid working model.
• Sustainable work location in Friedrichshain.
• Permanent employment contract.
• 30 days vacation.
• Discount on gyms (Fitness First, SuperFit, FitX).
• Employee discount on STRATO products and 1&1 products.
• Bicycle leasing with Eurorad.
• Health promotion offers such as group accident insurance, flu vaccinations, eye check-ups and co-payment for workplace glasses.
