Job Description

This role can be based from any of our offices or remote.

We’re making zero carbon happen

We’re OVO Group, a big family of companies united by a single vision: to get to zero carbon, fast. 

We call this Plan Zero – and it shows how we’ll be fighting the climate crisis and transforming the way people use energy over the next decade. To do this, we need the sharpest minds. Are you up for the challenge?

Do great green things with OVO Energy

So much has changed since we launched in 2009.  Our goal remains the same though: make energy cheaper, greener, and simpler. Just as it was on day one.

Everyone belongs at OVO

Our aim is to build a diverse and inclusive movement: teams of brilliant people, with unique talents, skills, passions, and experiences. 

We encourage everyone to join us, whatever your gender identity, race, ethnicity, sexual orientation, age, life experience, or background. So please come as you are – we can’t wait to meet you.

Where in the world of OVO will I be working?

Working within the Smart Meter Booking team, you will be joining full stack developers building the smart meter booking experience and backend systems for OVO customers and customer care agents across the website.

The team builds and maintains the journeys that our customers and agents use to create and manage their appointments for smart meter installations, with exciting opportunities to grow the range of products for which customers can make bookings. You will encounter Scala and Node on the back-end and maybe some React on the frontend, you’ll be expected to get involved with building and testing each part of the product.

This role sits within the Consumer technology organisation and allows you to get involved with architecture decisions and creation of new features, as well as exciting contributions to our ongoing efforts at improving and streamlining our products.

What will I be doing? 

As a Software Developer for our customer-facing journeys and back-end systems you will work within an engineering squad responsible for development and testing of our systems, with input from production engineers, product managers, and designers. You will report to the Software Engineering Manager and, under their supervision, be part of a team with full autonomy in designing and building new features and improvements. You may collaborate with other teams when adding new features and you will have the unique opportunity to be involved in re-architecting our platform as it expands to support other booking journeys.

You'll be working in an AGILE (hybrid Kanban/Scrum) team interfacing with multiple Product Managers. Planning, refinement, and retro sessions are a key part of the day-to-day team life.

Key responsibilities include: 

  • Developing new features by designing and implementing them following SOLID principles and using the appropriate design patterns
  • Maintaining existing code and writing automation tests to ensure the high quality of our web platforms and back-end systems
  • Diagnose and fix critical bugs, identify bottlenecks  and improve performance across our services
  • Write documentation for new and existing features
  • Coordinate with other team members, and members of our design and product teams

Is this job for me? 

We’d love to work with a mid to senior software engineer who’s looking for an opportunity to make an impact. If you love tinkering with back-end architecture, don’t mind the occasional bit of front-end if required and are passionate about creating best in class user experiences, this is the job for you!

Ideally you will have: 

  • Strong backend experience using Node and Typescript
  • Drive for technical excellence
  • Experience with test-driven development
  • A solid grasp of software engineering best practices
  • Experience with event driven micro services architecture
  • Experience working in an Agile team (Kanban and/or Scrum)
  • Experience working in a continuous integration and continuous delivery environment
