Mid-level Ruby on Rails Developer

We are looking for a backend Rails developer to join our team on a full-time basis to help build resilient device integrations, data crunching tasks, and fast and performant queries.

We support hybrid or fully remote working with the ability to travel to our Bristol-based office once a month.

About Amba

At Amba Health & Care Ltd our passion is keeping older people safe, well, and living independently for longer. We combine beautiful products, and the latest medical technology with a simple application to keep older people safe and well in their own homes while giving carers and families peace of mind. 

We are a small but ambitious team and although Amba is in its infancy, the team is well-rounded with a mix of skills and experience. 

Every developer in the team has a certain level of "full stack" so you’ll need to be comfortable writing features that will both involve Rails/ActiveRecord/Sidekiq but also dip your toes into the view side of things.

On top of the common stack, all our developers have, or are developing a particular skill or expertise. Some are more proficient in accessibility, others in Devops while some live and breathe API challenges.

“I joined the team nearly 4 years ago as a budding young software developer and I am so grateful for my experience here. The work culture is very nurturing. I was entrusted with opportunities and responsibilities early on. Pushed to create amazing software without worrying about the stress of failure. It really helped me to accelerate my growth, every day is a new learning experience.

I have great respect for the team’s drive to continuously develop new technologies, solve new problems, and improve working processes and employee skills. I like the informal work environment and direct way of approaching one another. This atmosphere keeps all employees closely involved in the company, and motivates us to do our absolute best.” 
James Reading, Ruby on Rails Developer, 2022

About the role

We are looking for someone who is driven to solve tough problems and continually consider the best ways to improve the health and well-being of older people. You will be working for a  genuine ‘tech for good’ company.

The work is varied and includes every aspect of Rails; one week you could be integrating a new device API; the following week, you could be deep into SQL optimisation or working on some refactoring.

How we work

Every day starts with a brief virtual stand-up to discuss progress. 

We work in 10 days sprints that start with a planning session where all features are discussed in depth by the development team. Typically the features are driven by user feedback and the product management team and aim to make the product better with every iteration.

At the end of each sprint, we do a quick retrospective to catch any urgent issues. Every 2 sprints, we organise a more in-depth retro to improve our process and practices. We encourage everyone to voice their ideas and concerns.

Every two sprints, we include a wriggle week, giving the engineering team a chance to decide what they would like to focus on.

As a developer you will:

  • Build and ship new features; helping our customers to look after vulnerable people more effectively. 
  • Write tests and fix bugs.
  • Review pull requests from other developers.
  • Drive continuous improvement of the product and the team.
  • Communicate on progress and report issues to management. 
  • Be responsible for feature deployment and help with Q & A from time to time.
  • Take responsibility and be ready to give a helping hand if something bad were to happen on production at any point (let’s hope it doesn’t though!)
  • Contribute to creating a strong culture of trust within the team.

Our tech stack:

We’re all believers in the big monolith approach and work as close as possible following "the Rails Way".

You can expect to be working with:

  • Ruby on Rails 6.x (soon 7.0)
  • PostgreSQL
  • Stimulus
  • Turbo
  • Soon we plan to introduce either StimulusReflex/CableRead or use the ActionCable/Turbo
  • Turbo iOS / Turbo Android mobile apps
  • ViewComponents
  • Webpacker, Bootstrap 5, yarn.
  • Sidekiq powers all our background jobs, and we’re running a ton of them.
  • Heroku


  • At least 2 years of Ruby/Rails experience
  • Good written and asynchronous communication skills (we use Asana and Slack to report on progress)
  • Confidence to ask for help when you’re stuck.
  • Collaborate effectively with other developers; by pairing or answering questions.
  • Take ownership of your tasks and responsibilities.
  • Manage priorities and adapt to change.
  • Be comfortable working with a hybrid team.
  • Ability to manage pressure even when things are going south.
  • Be passionate about the product
  • Ideally, you will be able to attend a monthly meeting at our Bristol head office but this is not a deal breaker. (If you’re not UK-based, your timezone should be UTC-2 to UTC+2 so we can have a good day of overlap)

Salary and benefits

We can offer you: 

  • Salary range: £40-60K p/a
  • Flexibility: This could be working from home, doing the school run, or life admin. We understand that flexibility is essential to a healthy work/life balance, so tell us what is important to you and we will try our best to accommodate.
  • Equity in the company through a share option scheme, because we want everyone to have a stake in our success. 
  • A generous holiday policy that includes 25 days of holiday, plus bank holidays, with an additional 2 days per year after 2 years of continuous service.
  • A salary sacrifice pension scheme and enhanced employer pension contributions.
  • Enhanced maternity and paternity leave.
  • A subscription to the financial wellbeing platform Mintago, with access to free expert advice and tools to help plan and manage your finances, helping to reduce financial stress. 
  • A life insurance policy with a lump sum payment equal to four times your salary made to your nominated beneficiary in the event of your death whilst an employee.
  • Discounts for online workouts and more than 3,000 health and fitness clubs nationwide.
  • A fascinating problem to solve; your feature may even save someone’s life one day. 
  • Lovely offices in a great Bristol location, along with fun social events.

We are always listening to our teams and evolving the benefits available to our people as we continue to grow.
