Not to mention the career paths this exciting space has created. emnify stands out by delivering the next generation of connectivity technology to IoT solution providers worldwide – either directly or via strategic partnerships with CSPs. The most exciting thing about working at emnify is that we are just at the beginning of our journey. We are constantly developing our culture, people and our business approach further. Our guiding principles are driving transformation, customer centricity and empowering people. If you share our vision to unlock the potential of connectivity in a people focused culture that gives you the chance for impact, growth and to be successful together, we would be happy to join us.

Your Role

As an Engineering Manager, you will lead a cross-functional team of 10 engineers (direct and indirect reports) responsible for emnify’s mission-critical core network services. These services ensure the connectivity, scalability, and reliability of our global infrastructure, enabling customer devices to connect across 500+ mobile networks worldwide.

This team designs, builds, and operates core components such as HLR/HSS, AuC, Diameter routers, SIGTRAN, SMSC, and other services that power authentication, signaling, and messaging for emnify SIMs globally.

We’re open to candidates from one of two technical backgrounds:

• Java engineers with strong Akka experience (ideally also Spring Boot and Kafka)
• Erlang/C++ engineers with production experience in telecom signaling environments

You will play a key role in guiding architecture and engineering practices, helping the team evolve from legacy systems to highly scalable, event-driven, cloud-native solutions, while fostering a high-performance and collaborative culture.

Location: Germany or Poland.

If based in Berlin, we expect you to join us in the office 3 days per week.

If based elsewhere, we ask for monthly travel to our Berlin office.

Your Impact

• Team Leadership & Engineering Culture: Foster a strong, quality-driven engineering culture rooted in modern practices (e.g. CI/CD, testing, clean code, system ownership). Guide team growth through mentorship and inclusive leadership.
• System Architecture & Design: Lead architecture and design discussions. Drive the evolution of our core network from a distributed monolith to scalable, resilient, event-driven services.
• Strategic Technical Initiatives: Enable large-scale transformations, including core network modernization and 5G readiness, through pragmatic leadership and collaborative planning.
• Cross-functional Collaboration: Work closely with product managers, telco engineers, and platform teams to align architecture with product and business goals.
• Operational Excellence: Ensure system reliability through robust testing, observability, and gradual rollouts. Balance roadmap execution with incident response and continuous improvement.

Your Skills

• Engineering Leadership: Proven experience managing and mentoring engineers, with the ability to lead through influence, foster autonomy, and drive alignment across teams.
• System Architecture & Design: Strong track record designing and evolving distributed, event-driven systems that prioritize high availability, scalability, and observability.
• Technical Competency: Hands-on experience in one of the following stacks: Java with Akka (Spring Boot and Kafka are a plus), or Erlang and C++ (Kafka is a plus).
• Telecom & Signaling Knowledge: Direct experience with mobile core network protocols and signaling (e.g. SIGTRAN, Diameter, HLR/HSS, AuC, SMSC), ideally in production environments.
• Cloud Infrastructure & Operations: Experience building and operating services in cloud-native environments (e.g. Kubernetes, AWS, Terraform), including monitoring and alerting.

Learning culture

It’s all about your growth. emnify puts a lot of effort into setting up different learning opportunities for everyone. We are currently focusing on leadership coaching with our partner Gallup with their strengthsfinder approach. We enable leaders to identify their strengths to continue their learning journey. We offer emerging leaders with our partner Junto to connect with other leaders from similar companies to learn together and grow a network. On top of that our employees benefit from lunch & learn sessions to learn and understand different parts of the business better and leverage the different skills from each other.

Celebrate success together

We empower leaders to spend some quality time with their teams and get together for dinners, workshops, or other fun activities. Building relationships in your team and beyond is key to form and maintain a high-performance culture that ensures a successful and competitive business. We want work to be fun and achieve challenging goals together. Beyond the quarterly events we also have company events like summer or christmas parties where everyone gets together to ensure people focused culture.

Flexible working approach

As a global company, our colleagues work around the world and in different time zones. Flexibility is key to us. emnify has chosen the hybrid approach to focus on growing their existing hubs further. Whereas our GTM organization in the US is completely remote because there is no hub for them yet. We offer professional relocation services, employer of record and remote working policy. We know great talents are spread around the world or have their families in different countries. We are not a remote culture. We believe driving transformation and embracing customer centricity can be done best in our hybrid working environment where we can learn and grow together.
