2nd Line Technical Support Engineer (IoT)

Join our team and become a key technical partner for enterprise customers using our IoT platform worldwide. Our platform is built around the LwM2M standard, a global protocol for secure, large-scale IoT device management, used in smart metering, utilities, and industrial applications. You will work on complex technical issues, maintaining production environments and ensuring high-quality service, while gaining deep expertise in large-scale IoT deployments.

This role emphasizes technical troubleshooting, systems analysis, and engineering problem-solving. You will work closely with internal teams and enterprise clients to investigate, debug, and resolve escalated technical issues.

Key responsibilities

• Provide advanced 2nd-line technical support, analyzing and resolving complex system, integration, and networking issues.

• Troubleshoot production environments, investigating device and platform behavior end-to-end, escalating only when necessary.

• Support enterprise customers during PoCs, rollouts, and production, including LwM2M deployments.

• Monitor system behavior and proactively identify potential issues to maintain platform reliability.

• Maintain and improve technical documentation, including troubleshooting guides and operational procedures.

• Contribute feedback from incidents and production operations to drive product and process improvements.

• Once fully onboarded, participate in a paid 24/7 on-call rotation. Interventions are rare, mostly monitoring and standby.

  
  

Requirements

• Bachelor’s degree in Computer Science, Telecommunications, or a related technical field.

• 3+ years of experience in technical support, system operations, or a similar engineering role.

• Solid understanding of networking fundamentals (DNS, DHCP, HTTP(S), TCP/UDP, PKI).

• Strong analytical mindset, attention to detail, and ownership of technical issues.

• Ability to communicate complex technical topics clearly to internal teams and clients when required.

• Fluent in Polish and English (spoken and written).
