Integration Software Engineer

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?

1. Intro video-call with HR (45 min) – expectations, background, role context + basic technical check

2. Technical and managerial interview [combined] (~3h) – programming, APIs, networking fundamentals + project discussion and working style

3. Final decision and feedback

The whole process usually takes 2–3 weeks

Come and work with the best!
