Software Engineer
Sedgefield | Hybrid working (typically 3 days on-site) | £38,000 - £46,000 per annum
About the Role
CPI is seeking a AI Software Engineer to join their Electronic Engineering team in Sedgefield, delivering AI, software and digital solutions as part of end-to-end product development programmes.
This is not a maintenance or support role; You will be involved in building real products - from initial concept through to deployment - working alongside electronics and hardware engineers to deliver innovative solutions used in healthcare, medtech, sensors, wearables, and industrial environments.
You will contribute to the full software lifecycle, including application development, cloud-based systems, and (where applicable) AI-enabled solutions. This role offers rare exposure to the complete journey from prototype to market, including integration with hardware, sensors, and embedded systems.
Hybrid working is supported, typically three days per week on-site, with flexibility depending on project needs.
What You'll Be Responsible For:
Product & Software Development
Design, build, and deliver software products from concept through to production
Contribute to full‑stack development across backend services, web, and mobile applications
Work closely with electronics and hardware engineers to integrate software with physical devices and sensorsCore Technology Stack
Develop backend systems and applications using Python (essential)
Build user interfaces and applications using React and React Native
Contribute to cloud‑hosted web applications, ideally using Node.js or similar technologiesAI & Advanced Software (where applicable)
Contribute to AI‑enabled applications, including data-driven and intelligent systems
Support model training, fine-tuning, and deployment where experience allows
Work with tools and approaches such as:
MLflow and model lifecycle tools
Gradient boosted trees or custom model development
AI application frameworks (e.g. LangChain, RAG-style architectures)Experience across both AI application development and model development is highly desirable, though not essential.
Collaboration & Delivery
Work within a small, highly capable multi‑disciplinary team
Take ownership for delivering complex software components in a hands-on way
Contribute to technical decision-making, architecture discussions, and solution design
Engage across busy project environments with frequent collaboration and stakeholder interaction
About You:
You are a hands-on software engineer who enjoys building products rather than maintaining legacy systems. You're comfortable working across multiple technologies and don't need everything tightly defined before you start.
You'll thrive in a small team environment, where flexibility, curiosity, and self-direction are valued.
You'll bring:
Strong Python development experience (essential)
Experience building applications using React and/or React Native
Full‑stack development experience with modern frameworks and technologies
Evidence of delivering complex projects or products
A practical, problem-solving mindsetDesirable (but not essential):
Experience with Node.js in cloud or web applications
Exposure to AI / machine learning, including model development or AI-powered applications
Experience with firmware, microcontrollers, Raspberry Pi, or embedded systems
Use of lightweight ML frameworks (e.g. TensorFlow Lite) on devices
Personal projects, side projects, or self‑driven development workCandidates who have worked in small teams or on self‑led technical projects often thrive in this environment.
Why Join CPI?
Rare opportunity to work on true end-to-end product development
Exposure to hardware, electronics, sensors, and software in one role
Challenging, varied technical problems across multiple industries
Small, collaborative team with wide technical scope
Competitive salary (£38k-£46k) and hybrid working
Location & Working Pattern
Based at CPI's Sedgefield site
Hybrid working typically 3 days on-site, with flexibility based on project needs
Some weeks may require increased on-site presence
Role operates in a busy, highly collaborative environment, so ideally someone who can work closely with hardware engineers onsite
