Job Description

Contract Software Lead Architect (IoT / Smart Systems)

6-month contract | Outside IR35 | Hybrid (UK)

Edison Smart is hiring on behalf of a long-established technology organisation that is investing in the next phase of its software and platform architecture.

This role sits at a senior level within the architecture function and will play a key part in defining how complex, connected systems are designed, secured, and scaled going forward. The successful contractor will have genuine influence over technical direction, not just delivery.

The Opportunity

You’ll take ownership of high-level software architecture across connected platforms, working closely with engineers, architects, and product stakeholders to translate strategic intent into practical, buildable solutions.

The environment suits someone who enjoys:

Modernising and reshaping existing architectures

Working across IoT platforms, integrations, and distributed systems

Operating hands-on while still thinking at system and roadmap level

Sector-specific experience (e.g. lighting or hardware) is not essential — strong architectural judgement and communication area.

Key Responsibilities

Define and evolve end-to-end software architecture for connected and IoT-enabled systems

Design scalable, secure, and maintainable architectures covering device connectivity, edge processing, and data flows

Set architectural standards, principles, and decision records

Guide teams on best practice across security, compliance, and system design

Collaborate closely with architects, engineers, and product leadership across multiple locations

Required Experience

5+ years’ experience operating as a senior or lead software architect

Strong background in modern software architecture, system integration, and distributed platforms

Hands-on knowledge of IoT protocols and patterns (e.g. MQTT, CoAP, AMQP)

Experience with device management and edge computing concepts

Solid understanding of cybersecurity considerations within connected ecosystems

Exposure to data pipelines, real-time processing, analytics, or ML integration

Excellent communication skills with the ability to bridge technical and non-technical audiences

Fluent English

Desirable Experience

Industrial IoT, smart devices, or smart building platforms

Embedded or firmware-adjacent architectural understanding

DevOps practices, CI/CD pipelines, and automated testing

Strong problem-solving mindset and interest in architectural improvement

Contract Details

Initial 6-month engagement with potential extension

Outside IR35

Hybrid working with regular onsite collaboration in the UK (driving recommended)

If you’re a senior architect who enjoys shaping systems rather than maintaining status quo, this is a high-impact contract worth exploring.
