Our Mission

We're not your average benefits platform; we're the unordinary force that uplifts people's lives. Our technology is the link that connects the entire benefits ecosystem, creating better outcomes for employers, employees, brokers, and providers.

Our mission is clear: we're here to create a world where everything operates at its very best, ensuring that every employee receives the support they need to live life to the fullest, both at work and beyond.

Your Mission

As a Senior Backend Engineer, you will play a big part in the development of the core API layer and business logic in our platform. You will challenge the complexity in the employee benefit domain and constantly deliver value (benefit!) to our users by building reliable and scalable software. You will also be expected to show some leadership skills to positively impact team productivity as a senior member of the engineering team.

We’re looking for self-starters who are seeking a fast-paced environment where they can make a difference. Our team is small, which means high autonomy, ownership, and responsibility. We love what we do, have fun and, while we ship on time, take life-work balance seriously.

Things you will be working on…

  • Design, implement and deliver software features with full ownership, using your technical expertise

  • Implement payment card APIs and payment transaction handlers

  • Integrate with HRIS (Human Resources Information System) and our benefit supplier partners

  • Take ownership of our employee benefits management platform and ensure their reliability

  • Lead and deliver your implementations from start to finish, including deployment of new services by expanding our application infrastructure within AWS

  • Drive initiative across squads to identify and solve important problems, coordinating with others on cross-cutting technical issues

  • Collaborate with product stakeholders and other members of the team to scope and estimate optimal solutions for business problems

  • Ensure that security considerations are taken into account, based on current best practices (e.g. OWASP Top 10, AWS Well-Architected Framework) in all software development and infrastructure projects

Behind the scenes

Our cross-functional delivery team is focused on business goals and solving problems in an efficient manner. We want the team to collaborate on new ideas and projects to find the best solutions.

Ben is built on Python 3, Django, Go, PostgreSQL and React. We run on AWS and follow engineering best practices, with a pragmatic approach.

We've just released our first ever Go service at Ben, so, whilst the language is relatively known, there's still huge amounts of work to be done here!

You’ll love this role if you are/have:

  • Strong commercial experience working with Python or Go

  • Experience with Temporal (nice to have)

  • Deep architectural & design pattern experience; drive the design & planning, collaborate with teammates, and set up new projects to ensure architectural success.

  • Apply information security in building secure web applications and infrastructure configurations

  • Understand and appreciate the principles and practices of agile and lean ways of working, but with a pragmatic edge

  • Excellent communication skills adaptable to both tech and business audiences

  • Experience in working with AWS services such as EC2, SES, S3 etc.

and you...

  • are a self-starter who thrives on autonomy, enjoys a rapid pace and wants to make a difference

  • have a continuous improvement mindset. You appreciate that there are always ways to do things better and ensure your team does too

  • have a preference to action-oriented behaviour with just enough analysis, as compared to too much time spent doing analysis with no action

  • have the ability to make decisions balancing different factors such as business requirements, technical integrity, overall priorities etc.

  • appreciate the opportunities and challenges of a distributed work environment

  • are solution-focused with a pragmatic approach to problem-solving

Diversity and Culture at Ben

We are organically growing a brilliantly diverse, inclusive and respectful bunch of people we are extremely proud of. This should go without saying but all applications are very much welcome. If you need any adjustments to support you with your application, just let us know by emailing
