Backend Engineer & Senior Backend Engineer

We're putting together a talented team to build the world's best calendar

Daybridge is the calendar the world's been waiting for. Unlike traditional calendar apps, it'll be expressive, intuitive, smart, and beautifully designed. Users will be able to add personal context to their plans, better manage their work/life balance, and more easily find time with others.

You'll build Daybridge with us

As one of our first Backend Engineers, you'll help shape both our product and the culture of our company. You'll work closely with Daybridge's founder and CEO, Kieran, who'll give you all the support you need.

Each day is often different, but you'll typically be working with our team to:

  • prioritise, build, and test product features, bug fixes, and performance improvements
  • decide on the most appropriate system architecture to support new features
  • help us operate more efficiently, by building and maintaining our developer tooling and continuous integration pipeline
  • instrument and monitor our production environments, and to respond to incidents

Who we're looking for

We're looking for smart, creative, and dependable engineers who want to make their mark at an early-stage company. You should apply if...

  • you have strong opinions on how to design, build, and operate consumer-facing products
  • you're a good communicator, and able to give and receive constructive feedback
  • you're flexible, and enjoy learning new technologies and pitching in on tasks outside of your discipline
  • you're excited by the opportunity to join an early-stage team, and to build a culture and company from the ground up
  • you're comfortable joining our on-call rota

What experience we're looking for

We're looking for people who:

  • have experience designing, building, and operating production systems
  • are comfortable navigating and implementing standards and RFCs
  • can design and implement performant, secure, and reliable APIs
  • have good writing skills, and are able to write clear and concise proposals
  • are able to carry projects from an initial idea through to a performant and reliable final implementation

Our technical stack

We use TypeScript as our main language, which allows us to efficiently share code across our frontend and backend. We also use:

  • Google Cloud Run for our backend application code
  • Google Cloud Firestore (in Datastore mode) for persistent data storage
  • Firebase Authentication for identity management
  • Google Cloud Pub/Sub for asynchronous messaging
  • HashiCorp Terraform for provisioning our infrastructure
  • GitHub Actions for continuous integration and deployment
  • Docker for packaging up and deploying our backend

Interview process

We want our interview process to be as straightforward and enjoyable as possible. The first step will be a quick call to discuss the basics of the role and to help decide if we'll be a good fit. We'll then follow up with a coding exercise - or, if you prefer, you can provide us with an interesting piece of code you've already written, which we'll discuss.

There'll also be a one-hour general technical interview (no trick questions or whiteboard exercises), which could either be wrapped into the coding exercise or completed at a later date.

Once the process is finished, we promise to let you know our decision as soon as possible.

How to apply

Please email your CV to, along with anything else you think might help your application. In your email, tell us a bit about you, how you found Daybridge, and what excites you about the possibility of working with us!

We'll be in touch with next steps as quickly as we can.

Benefits and options

We offer a salary of £40,000 — £80,000 (negotiable), plus 0.4% — 0.8% ownership of Daybridge via tax-efficient EMI stock options.

We'll be growing our package of benefits over time. We currently offer:

  • Flexible working (we're all currently working from home, with occasional days together in person)
  • Comprehensive private medical insurance, with dental and mental health cover
  • Comprehensive income protection, so you'll still get paid if you fall ill and can't work
  • Life assurance for 4x your annual salary
  • Salary reviews every six months and whenever we raise more investment
  • 33 days flexible holiday, with the choice to use your bank holiday allowance on days that better suit you
  • 14 days paid sick leave, as well as paid mental health days, with more available if you need it
  • Paid bereavement and compassionate leave
  • A workplace pension scheme where we pay 3%, if you pay 5%
  • A brand new MacBook Pro, 4K display, and any other equipment you need
  • Regular (and optional) team socials

Our culture

We're committed to building a diverse and inclusive team where everyone is empowered to do their best work. You'll feel welcome at Daybridge regardless of your gender, ethnicity, sexuality, disability status, nationality, age, or religion. We'll aim to hire people who have faced structural barriers to entry in the technology industry.

We strongly believe that performance and ambition shouldn't come at the cost of mutual respect and thoughtful communication.

Creative and entrepreneurial
We'll give you the space to try out new ideas, and the support you need to ship them.

We'll trust you to take ownership of your discipline and role.

Happy and healthy

Frequently asked questions, answered.

Are you looking for freelancers or contractors?
We regularly work with contractors and freelancers to support us with smaller projects, mostly in non-engineering roles. We prefer to work with people on a full-time basis so we can offer ownership in the company. However, our priority is to work with the best people regardless of their situation; so are open to freelancers and contractors who only want to work with us on a temporary basis.
Do you offer internships or placements?
While we have no formal internship programme at Daybridge, we'll always consider exceptional candidates with experience working on production systems. We're also happy to meet candidates interested in future roles at Daybridge (e.g. following graduation).
Where are your offices?
We're currently working from home, but have office space in London, UK - near Farringdon station.
Do you hire recent graduates?
We welcome graduates to apply for a role at Daybridge. In your application, you need to demonstrate relevant experience: whether through employment and internships, or through personal projects and contributions to open source.
Can you sponsor visas?
We can't sponsor visas right now. We'll be working on securing a visa sponsorship license in the future.
Do you work with recruiters?
We aren't working with recruiters right now, but this might change in the future.
