Why should you join us?
AVSystem is the company behind the Unified Management Platform (UMP) – a solution used by Tier-1 telecom operators such as Orange, Vodafone, AT&T and T-Mobile. Our software enables automatic configuration, upgrades and monitoring of millions of routers worldwide.
This role has real impact. You won’t be building internal tools or proof-of-concepts — you’ll deliver solutions that run in production environments at global scale.
As an Integration Software Engineer, you will:
- combine software engineering with real networking environments,
- work directly with customers and see the results of your work,
- develop expertise at the intersection of backend development, integrations and networking,
- collaborate closely with domain experts (Senior Engineers, Product Owners, Solution Architects) from the very beginning,
- learn and use our Scala-based functional DSL designed for large-scale device management.
This role is a strong fit if you want to:
- understand systems end-to-end
- take ownership of production-grade integrations
- grow toward Solution Architecture, system integrations, or telecom/IoT domains
What does the day-to-day work look like?
Your work combines development, system integration and project collaboration
In practice, you will:
- write project-specific code (Python and our in-house functional language)
- implement and integrate REST APIs (both client and server side)
- configure UMP for specific customer deployments
- work with routers and external systems
- analyze logs and troubleshoot issues (Linux CLI, tcpdump, curl, ssh)
- collaborate with Solution Architects and Software Engineers (including code reviews)
- support your integrations after delivery together with 1st and 2nd line support teams
Work distribution typically looks like:
- 40–50% development and configuration
- 30–40% integrations and troubleshooting
- 10–20% direct customer communication (calls, emails, support portal)
The pace can be project-driven — especially around delivery milestones
What do you need to succeed?
- Strong programming skills (Python preferred)
- Experience with REST APIs (client and/or server side)
- Understanding of networking fundamentals (HTTP(S), TCP/IP, WLAN, firewalls)
- Basic Linux administration skills (log analysis, CLI tools, ssh, tcpdump)
- English proficiency (B2/C1)
- Willingness to learn our Scala-based functional DSL
Nice to have:
- Professional experience as a Software Engineer
- Experience in multi-system integration environments
- Telecom domain exposure (ACS, NMS, OSS, BSS)
What does the recruitment process look like?
- Intro video-call with HR (45 min) – expectations, background, role context + basic technical check
- Technical and managerial interview [combined] (~3h) – programming, APIs, networking fundamentals + project discussion and working style
- Final decision and feedback
The whole process usually takes 2–3 weeks
