Job Title: Junior Full Stack Developer
Reports To: Head of IT & Software Development
Location: On-site Winnersh Triangle office
Employment Type: Full-time
Focus: Primarily frontend, extending into backend (C#/.NET) as features require
We're looking for a junior developer to join our in-house software team working on Taskye, our bespoke Computer-Aided Facilities Management (CAFM) platform. You'll spend most of your time building front-end features, with the opportunity to pick up backend work as your skills grow and the roadmap demands it.
About Us FISco Uk Ltd is a facilities management company delivering total FM services, hard services and soft services, through a network of third-party contractors, acting as the intermediary between clients and providers.
At the center of that operation is Taskye, our CAFM system, built and maintained entirely in-house rather than bought off the shelf. It's the tool our team, our clients, and our contractor network use every day, which means the software you ship has a direct, visible impact on how the business runs.
Key Responsibilities
- Design, build, and maintain UI features across Taskye's Next.js/React frontend, working within our existing component library and coding standards
- Extend or consume backend APIs (C#/.NET 8 microservices) when a feature calls for it
- Write tests for any work you pick up
- Work through Git and Azure DevOps and track work in Jira
- Learn and follow Taskye's established architecture and conventions
Core Skills Tech Stack & Essential Skills

- Next.js
- HTML & CSS

- C# and .NET 8
- T-SQL
Tooling used across the team: Azure DevOps (source control and CI/CD), Azure (cloud hosting), Jira (ticketing).
Desirable / Nice-to-Have
- Exposure to Flutter/Dart
- Familiarity with Azure cloud services
- Any experience with automated testing (Jest, React Testing Library, xUnit, or similar)
- Experience in infrastructure-as-code (Bicep) or CI/CD pipelines
- A relevant degree, bootcamp, or personal/university projects demonstrating your work
What We Offer
- Hands-on mentoring from a small, experienced in-house development team
- Real ownership of features in a live product used daily across the business
- A structured path designed to help your skills grow
- On-site, collaborative team environment
- Onboarding into our established coding standards and architecture
