Job description

Full Stack Developer - .NET/React/Azure

Eastleigh (3 days onsite/2 days WFH) £55,000 - £65,000 + 15% bonus + benefits

My client, a rapidly growing leader in the water treatment and utilities technology sector, is seeking an experienced Full Stack Developer to join their expanding engineering team. This is an exciting opportunity to work on a greenfield enterprise platform, building the next generation of IoT/telemetry monitoring solutions used across water treatment, pump systems, and utility environments.

The business has grown significantly over the last 18 months and plans to scale by a further 30% next year. As a Full Stack Developer, you'll be a key contributor in designing and delivering the company's new customer portal, Back End APIs, and integrations with Real Time IoT infrastructure.

The Role

You will design, build, and maintain secure, scalable software across both Back End (.NET) and Front End (React) ecosystems, working closely with product, engineering, and operations teams. You'll help shape best practices, support junior developers, and ensure the delivery of robust cloud‑native solutions.

Technical Environment

Backend (primary focus)

• .NET 8
• Mix of .NET Core and .NET Framework (approx. 50/50)
• Building APIs powering the IoT device fleet and customer portal
• RESTful API design (GraphQL beneficial, not essential)

Frontend

• ReactJS
• Open to strong Front End engineers willing to transition to React
• React Native experience is a plus

Cloud

• Azure preferred (App Services, Storage, IoT Hub, Event Hub, Data Explorer)
• Open to AWS or GCP candidates with strong cloud integration experience
• Must understand cloud deployments, monitoring, and API integration

DevOps

• CI/CD pipeline setup and maintenance
• Monitoring, observability, automated deployments
• Strong engineering hygiene (not a DevOps role, but good DevOps practices required)

Security

• Secure coding principles
• Authentication/authorisation (OAuth2, Entra ID/B2C)
• Role‑based access control (RBAC)

Key Responsibilities

• Design, develop, and deploy full stack web applications using .NET and React.
• Build and maintain Back End APIs to support internal systems, IoT telemetry, and customer‑facing applications.
• Develop new features for the customer portal including dashboards, mapping, device status, alerts, and access control.
• Integrate cloud resources and ensure scalable, secure deployments.
• Contribute to CI/CD pipeline development and best practices.
• Support the engineering team through code reviews, mentoring, and technical guidance.
• Collaborate with technical and non‑technical stakeholders across the business.

Industry Experience (nice to have)

Candidates from the following sectors will have an advantage:

• Water Industry
• Utilities
• Engineering
• Plant Hire
• Construction
• Civil Engineering

Why Join?

• Opportunity to build a greenfield platform from the ground up
• High‑growth company with strong investment
• Work directly on impactful IoT and telemetry solutions
• Clear progression opportunities as the team scales
• Supportive, collaborative engineering culture
