Junior Network Development Engineer

About Opplane

Opplane helps organizations unlock the value of their data in a world increasingly shaped by artificial intelligence, connectivity, and regulation.

We work with businesses across complex, data-intensive industries to turn fragmented or difficult-to-use data into trusted, actionable intelligence. Our work spans connectivity technologies, AI and data solutions for banking and fintech, and data governance and modernization.

Our founders and leadership team bring decades of experience in networking, wireless and telecom, having built and scaled multiple technology companies, several of them acquired by leading networking and technology players. Drawing on years of selling networking infrastructure, we are involved in building critical infrastructure for telecom operators, developing carrier-grade, software-based solutions that help them deliver secure, scalable connectivity to their enterprise customers.

Why this role matters

Our telecom products run on networking software built close to the packet: code that handles traffic, protocols and tunnels at carrier scale. Keeping that software reliable means fixing issues quickly and understanding why they happened.

In this role, you’ll start by learning our products and working on smaller issues alongside senior engineers, helping them diagnose and fix problems. It’s a hands-on way to build real depth in networking software, where the answers come from understanding the code and the protocols.

What you’ll do

• Learn how our networking products are built and how they run in operator environments
• Investigate and fix smaller issues in existing C/C++ code, with guidance from senior engineers
• Help senior engineers reproduce, debug and resolve product issues
• Support the product by analysing logs and test results to find the root cause of problems
• Test your changes, and document what you found and how you fixed it
• Take on more complex work as your understanding of the product grows

What you’ll bring

Experience and expertise

• A degree in Computer Science, Electronics, Telecommunications or a related field
• 2+ years of experience in networking software development
• Solid programming skills in C and/or C++
• Familiarity with networking protocols across layers 2 to 4
• Working knowledge of IPsec and SSL/TLS
• Experience with overlays and tunnelling (e.g. VXLAN, GRE)
• Experience with Docker and Kubernetes
• Good written and spoken English

How you work

• Curious and keen to learn, and comfortable saying “I don’t know yet”
• You can explain the code you’ve written
• Methodical when debugging: you look for the root cause, not just a quick fix
• Ask for help when you’re stuck, and take feedback on board
• Communicate clearly with colleagues in a distributed team

Nice to have

• Understanding of DPDK
• Experience working in cloud environments

What you’ll have the opportunity to do

• Build deep, hands-on expertise in networking software, working directly in the code
• Learn from senior engineers with long experience in networking and telecom
• Grow your scope as you learn the product, from small fixes to more complex work

How we work

Small team, big challenges, real ownership. At Opplane, you’ll work on software and technology across data, AI and connectivity, helping build solutions that address complex technical and business needs. You’ll have access to leadership, opportunities to contribute to technical decisions and room to influence how we approach problems and build our products.

Depending on your role, you may collaborate with colleagues, clients and stakeholders across the US, Portugal, Singapore and India. Our work brings together different areas of expertise and perspectives, making it important to stay curious, exchange ideas and understand the challenges others are working to solve. We value people who take initiative, share their knowledge and bring new perspectives to the way we work.

Ultimately, it’s about bringing people and technology together to build solutions that meet today’s needs and anticipate tomorrow’s challenges.
