To make IoT management a breeze for any device, anywhere. With over 10 million IoT subscriptions active in 165 countries and direct partnerships with 50 mobile networks, we connect you to more than 750 networks worldwide, delivering unmatched value across the IoT connectivity chain.

We offer industry expertise, stellar service support, and the most flexible, resilient, and secure connectivity solutions on the market. Our expertise spans across various sectors, including industry, agriculture, healthcare, security, transport, utilities, and smart cities.

IoT… a fancy acronym or a secret code?

The Internet of Things (IoT) is like the magical glue that keeps the world connected! 🌐✨ From ordering your favourite takeaway to the ANPR technology that helps you find a parking spot, IoT is everywhere—even if you don’t realize it. At Wireless Logic, we provide cutting-edge connectivity solutions and technologies to ensure a vast array of devices stay seamlessly connected.

As we evolve toward a Product Operating Model, we’re building empowered, outcome-driven squads. One of these is the Network Capabilities Squad, and we’re hiring a Senior Full Stack Engineer to help us realize our bold vision of seamless, intelligent, and adaptive global connectivity.

About the Network Capabilities Squad

Our long-term mission is to enhance global connectivity with optimized performance, resilience, and compliance across diverse geographies and network conditions. The Network Capabilities Squad ensures Wireless Logic can meet the demands of global IoT customers through intelligent, high-availability services.

We’re building a unified, next-generation connectivity platform anchored by a Tier 1-grade mobile core, eUICC-compliant SIMs, and dynamic multi-IMSI capabilities. This platform empowers customers with:

• Global Network Management: Multi-region connectivity orchestration

• Performance Monitoring: Latency, uptime, and service reliability metrics

• Compliance Management: Regulatory awareness and controls across markets

• Connectivity Optimisation: Seamless transitions across cellular, satellite, and Wi-Fi networks

Your work will directly impact global customer experience, enabling businesses to scale and adapt confidently in any region or condition.

Your Key Responsibilities

As a Senior Full Stack Engineer, you'll focus on backend systems with occasional contributions to frontend interfaces when needed. You will:

• Design and build scalable backend services and APIs using Java

• Integrate with core mobile network components and third-party APIs

• Collaborate on systems for connectivity monitoring, network intelligence, and compliance enforcement

• Contribute to platform automation and internal tooling for streamlined SIM, MNO, and network operations

• Support and maintain high-availability infrastructure and disaster recovery solutions

• Lead technical discussions, participate in architectural decisions, and conduct code reviews

• Ensure observability, performance, and security in everything you build

• Participate in Agile ceremonies and contribute to incremental product delivery

Your Skills & Experience

You’re likely a great fit if you bring most of the following:

• Strong backend engineering experience with Java

• Experience with microservices, REST APIs, and event-driven architectures

• Knowledge of container orchestration (e.g., Kubernetes)

• Exposure to connectivity platforms, mobile networks, or telecom infrastructure is a plus

• Experience with monitoring, alerting, and observability tooling

• Familiarity with SQL/NoSQL databases and distributed systems

• Security-first mindset with an understanding of compliance/regulatory-sensitive systems

• Comfortable working in cross-functional Agile squads

• Familiarity with Frontend development is a nice to have

• Willingness to learn React.js for occasional frontend tasks

Who You Are

• A pragmatic problem-solver who builds for scalability and resilience

• Motivated by impact and user outcomes — not just code

• Willing to explore unfamiliar parts of the stack to get things done

• Communicative and collaborative — you thrive in transparent, diverse teams

• Committed to learning, sharing knowledge, and mentoring others

Our Culture & Benefits

At Wireless Logic, we foster a culture of trust, ownership, and collaboration. You’ll be empowered to make decisions, try new approaches, and deliver meaningful solutions. We embrace flexibility, support lifelong learning, and encourage knowledge sharing across teams.

Some of our benefits include:

• 26 Paid Vacation Days + Polish Bank Holidays

• Flexible working arrangements

• Ongoing learning & development budget

• Inclusive, friendly, and innovative workplace
