Multiple locations
Hybrid
Mid
£52,000 - £59,000

Ready to work somewhere that cares more about how you build software than how fast you can ship it?

At Opencast, we don’t measure developers by the number of tickets you complete. We care about engineering craft, clean design and thoughtful problem-solving.

Opencast consultants deliver in complex environments, pairing often and working with others who take pride in doing things properly: TDD, emerging design, refactoring and leaving code better than they found it. We build software we are proud of, and our clients trust us not just to code but to think, challenge and guide. If you value simple and robust solutions and want a role where your judgment matters as much as your keyboard, you will fit right in.

The role

Software developers at Opencast care about building products right and combine their own experience and approach with our company values. They are tech agnostic, have expertise in agile methodologies, eXtreme programming practices and use industry-leading programming languages to deliver agile transformation.

Our approach to software development is collaborative, focused on keeping things simple, and we use test driven development and pair programming as best practice.

Working with clients and key stakeholders is a crucial part of a consultancy role. Our developers are inclusive team players that listen, collaborate, can positively challenge and manage expectations when needed but most of all are always willing to teach and help others. Leaving a client with improved ways of working, working technology and a good experience from discovery through to live is the priority.

The role is varied, technical, never confined to any one provider or solution and there are always opportunities for learning and development.

Requirements

Due to the nature of this role, applicants must either currently hold active Security Check (SC) Clearance or be eligible to obtain it.

Eligibility typically requires UK citizenship and continuous residence in the UK for the past five years, with no single absence exceeding 28 consecutive days.

Experience in delivering digital services for the UK government is highly valuable for many of our projects. Therefore, familiarity with the GDS toolkit or experience of working in the public sector is required.

Technical Skills

  • Expertise in Java or Scala is required
  • Experience in other languages such as Kotlin, Ruby or Javascript is also valuable
  • Understanding of Object Oriented Programming
  • In depth knowledge of concepts and uses of testing
  • Knowledge or experience of delivering complex services to Government Digital Service (GDS) standards
  • Being comfortable with new technology, t-shaped and comfortable with ongoing learning and development is key to success
  • Experience with agile methodology

A consultant in software development at Opencast is responsible for:

  • Delivering in the upkeep of their team’s backlog
  • Collaborating with the teams testing effort

Ready to work somewhere that cares more about how you build software than how fast you can ship it?

At Opencast, we don’t measure developers by the number of tickets you complete. We care about engineering craft, clean design and thoughtful problem-solving.

Opencast consultants deliver in complex environments, pairing often and working with others who take pride in doing things properly: TDD, emerging design, refactoring and leaving code better than they found it. We build software we are proud of, and our clients trust us not just to code but to think, challenge and guide. If you value simple and robust solutions and want a role where your judgment matters as much as your keyboard, you will fit right in.

The role

We’re looking for Contractors in Software Development (consultant level) to help our major clients transform.

Software developers at Opencast care about building products right and combine their own experience and approach with our company values. They are tech agnostic, have expertise in agile methodologies, extreme programming practices and use industry-leading programming languages to deliver agile transformation.

Our approach to software development is collaborative, focused on keeping things simple, and we use test driven development and pair programming as best practice.

Working with clients and key stakeholders is a crucial part of a consultancy role. Our developers are inclusive team players that listen, collaborate, can positively challenge and manage expectations when needed but most of all are always willing to teach and help others. Leaving a client with improved ways of working, working technology and a good experience from discovery through to live is the priority.

Contractors at Opencast follow the same principles as permanent consultants. The roles are varied, technical, and never confined to any one provider or solution.

Requirements

Due to the nature of this role, applicants must either currently hold active Security Check (SC) Clearance or be eligible to obtain it.

Eligibility typically requires UK citizenship and continuous residence in the UK for the past five years, with no single absence exceeding 28 consecutive days.

As attendance at client sites is a routine part of the role’s working pattern and involves occasional travel, travel expenses are not covered.

Experience in delivering digital services for the UK government is highly valuable for many of our projects. Therefore, familiarity with the GDS toolkit will be beneficial.

Technical Skills

  • Expertise in Java and/or Scala is required
  • Experience with Javascript, Typescript, Kotlin, Python or Ruby is also valuable
  • Understanding of Object Oriented Programming
  • In depth knowledge of concepts and uses of testing
  • Knowledge or experience of delivering complex services to Government Digital Service (GDS) standards
  • Being comfortable with new technology, t-shaped and comfortable with ongoing learning and development is key to success
  • Experience with agile methodology
