Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Solution Architect (IoT Connectivity) - **Company:** Inbound Talent - **Location:** Leeds, UK - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), User Authentication, Failover, Mobile Virtual Network Operator, E2e Testing, Systems Integration, Network Switches, SIGTRAN - **Published:** July 2, 2026 - **Apply:** https://find.jobs/jobs-near-me/apply/ats-redirect/?id=2850740784-2 ## About the Role * Extensive hands-on experience in mobile core, signalling or IMS, from an MNO, MVNO, IoT operator, MVNE or telecoms vendor * End-to-end VoLTE IMS deployment and integration experience, not just one layer of it, the whole thing * Deep SS7 and SIGTRAN knowledge: point codes, global title translation, STP configuration * Strong Diameter and DRA experience: routing realms, peer configuration, failover, integration with HSS, OCS and PCRF * SIP and IMS call flow expertise: VoLTE registration, authentication, call setup, troubleshooting at trace level * HLR/HSS subscriber provisioning, profile configuration, roaming behaviour and integration * Hands-on experience with BroadForward signalling platforms and/or Nokia CMP is advantageous * Someone who has delivered end-to-end, not just one piece, and who can self-start and be the single point of technical reference when needed ## Description This is a senior individual contributor role. You won't be managing a team, you'll be the technical authority. Designing the solution, producing the documentation, doing the hands-on integration work, and spreading knowledge across the engineering team as you go. * Owning the end-to-end integration of a new VoLTE IMS platform into the live mobile core, the first and most critical project for this person, with the RFP already underway * Designing and delivering customer signalling integrations: IMSI donation, core network integration, signalling interconnect, API and billing integration * Leading technical workshops with customers and internal stakeholders, translating requirements into secure, production-ready designs * Producing HLDs, LLDs, call flows, signalling diagrams, test plans and operational runbooks * Acting as the senior escalation point for complex signalling, IMS, VoLTE, Diameter, SS7 and charging issues * Mentoring the wider engineering team and building internal capability across mobile core, signalling and IMS domains Once the VoLTE IMS project is delivered, the next phase brings STP and DRA deployment, direct signalling link provisioning, and HLR/HSS migration. This is project-based work with multiple concurrent workstreams, it won't slow down. ## Related Videos - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) - [Let's get visual - Visual testing in your project](https://www.wearedevelopers.com/videos/540-let-s-get-visual-visual-testing-in-your-project) - [System Resilience: Surviving the Software Storm](https://www.wearedevelopers.com/videos/874-system-resilience-surviving-the-software-storm) - [Code meets connectivity - Developers as the powerhouse of Network API innovation](https://www.wearedevelopers.com/videos/1686-code-meets-connectivity-developers-as-the-powerhouse-of-network-api-innovation) - [Why I Love End-2-End Tests and How To Get Them Right](https://www.wearedevelopers.com/videos/996-why-i-love-end-2-end-tests-and-how-to-get-them-right) - [Fault Tolerance and Consistency at Scale: Harnessing the Power of Distributed SQL Databases](https://www.wearedevelopers.com/videos/1146-fault-tolerance-and-consistency-at-scale-harnessing-the-power-of-distributed-sql-databases) ## Related Articles - [The CAMARA Project: How Telcos Collaborating Improves Developer Experience](https://www.wearedevelopers.com/magazine/671-the-camara-project-how-telcos-collaborating-improves-developer-experience) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
