About One Big Circle

Be part of an award-winning workplace: The Sunday Times Best Medium-sized Technology Company 2025

Formed in 2017, One Big Circle is a fast-growing Bristol technology company that provides “Intelligent Video” solutions. We focus entirely on solving real-world industry problems by fusing new technology in the field of Video, IOT, Cloud and AI providing end to end solutions which allow our customers to dramatically improve their operational efficiency and safety. Our culture is one of high-quality technical delivery and we work at a speed that many industries are unaccustomed to; we have done this by building a team dynamic that challenges and empowers our people and creating an environment where everyone contributes and learns. We are growing, profitable and have ambitious plans to continue expansion in and beyond our existing markets.

We are looking for a proactive and motivated individual to join our team to support the business.

We have built a culture where people feel supported, included, and empowered to do their best work. Our team is growing, and we’d love for you to be part of the journey.

Role Summary

An exciting opportunity to kick-start your career as a junior software engineer in a fast-growing, office-based, hands-on team. This role is ideal if you enjoy being a broad generalist - someone who likes connecting systems, figuring out how different technologies work together, and building practical solutions that make things happen.

You’ll be working across a range of projects and products, helping to integrate services, move data between systems, and turn complex processes into reliable, working software. We don’t expect you to know everything upfront - what matters most is your curiosity, your willingness to learn by doing, and your interest in understanding how real-world systems fit together.

Responsibilities

You will help create and test software within a skilled team that likes getting things done.
You will learn a range of current and new technologies from experienced software and hardware engineers.
You will be given increasing responsibility for elements of each project as you continue to prove yourself.

There is flexibility in shaping the role around your strengths and interests, but some of the key technical areas you might encounter are listed below:

You’ll gain experience of a range of full-stack relevant technologies such as:

Python, C#
Video Streaming
Complex data-platform architecture, multi-tenant, partitioned, and access-controlled environments supporting secure and scalable data access
Docker & Microservices
Modern Web Applications built in React.js, and TypeScript

Personal Qualities and Experience

You are someone who enjoys learning new skills, finding out things and also learning from mistakes. We’d like you to be reliable, curious, and ready to deal with problems and get them solved. We strongly encourage those from under-represented groups to be confident in applying to us.

You do not need to have any formal experience working in software, but you should be able to demonstrate your interest by having done something or worked on a ‘passion project’ yourself. You might have built a full-stack web app, made something interesting using AWS services, built and optimized CICD deployment pipelines, or some other relevant activity. You should have some familiarity with at least one general purpose programming language.

You will also be keen to contribute ideas to both the business and the social side of the company.

Company Benefits Include:

Auto enrolment Pension Scheme
25 Days Holiday plus bank holidays
Life Assurance
Private Healthcare Cover
Work related training courses as required
Complimentary snacks and refreshments including fresh fruit
Office-Centric role
Access to Bike to Work Scheme
Secure bike storage and shower facilities
Social events

How to Apply

Join an award-winning team, named ‘The Sunday Times Best Medium-sized Technology Company 2025’. At One Big Circle, you’ll be part of a fast-growing team where your ideas and contributions are truly valued.

Please send your CV and covering letter to [email protected].

By applying for this role, you understand that we will process your personal information in accordance with our privacy policy, accessible at https://onebigcircle.co.uk/privacy-policy/

Successful applicants will be required to pass a BPSS (Baseline Personnel Security Standard) check.
