Software Engineer; Mid and Senior Levels

Software Engineer (Mid and Senior Levels)

One Big Circle – Bristol

The software technology team at One Big Circle is expanding! We are looking for software engineers at all levels of seniority and experience to integrate into our existing team and work across our diverse technology estate.

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 in further growing our flagship award‑winning product: AIVR. AIVR (Automated Intelligent Video Review) is a state‑of‑the‑art video technology system used by thousands of people in the rail industry. AIVR has won dozens of awards and is recognised as the market leading solution, but we are building many more opportunities both in existing and new markets which will further accelerate our growth.

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.

We have a number of roles available that are suitable for engineers with circa 3+ years of experience from ‘mid level’ up to senior. The roles span a number of broad capability areas which describe the kinds of problems we work on. They are not checklists, we recognise that candidates will bring depth in some areas and interest or exposure in others.

We encourage interest from applicants with partial or adjacent skills and backgrounds, to fill a number of different roles within each capability area.
