Friday is looking for a Senior Frontend Engineer

About Engineering at Friday

Engineers at Friday are committed and passionate technology enthusiasts. We focus on the heavy lifting of application architecture, data modelling, application logic, data services and REST APIs, both in the browser and on the server. Our engineers have deep specialist skills in one or two parts of the stack (from prototyping and front end, to backend, infrastructure and QA), however, we encourage a full-stack attitude: an understanding of the whole project lifecycle and an ability to navigate, communicate and practice at opposite ends of the stack.

We pride ourselves on our strong engineering practice; from open sourcing our own tools and practices, adopting collaborative and empowering methods such as TDD, BDD and Specification by Example, establishing a QA and DevOps culture within all teams, embracing mobile-first responsive design by default and striving for a culture of continuous learning.

What you’ll do

As a Senior Frontend Engineer you will work in an agile environment to conceive, describe and craft, beautifully useful digital services. You will work on high profile projects, building responsive websites and mobile applications. You’ll gain exposure to the full stack utilising continuous integration processes and a broad range of technologies to deliver a high-quality customer focused experience across a range of devices.

Everybody at Friday is client-facing, so when you’re not writing code you will be assisting with pitches, running Specification by Example workshops, or doing feature demonstrations. You’ll be encouraged to innovate and share knowledge with your team.

About the Role

As a Senior Frontend Engineer, your key tasks and responsibilities will be to:

  • Develop high-quality websites and applications using well-crafted HTML, CSS and JavaScript including supporting backend development using Node and other frameworks where required
  • Collaborate closely with our designers to develop in-browser prototypes, living styleguides, pattern libraries and re-usable UI components
  • Work closely with our in-house QA team to marry unit tests with rigorous end-to-end testing to ensure applications function as expected
  • Assist the delivery team with specification workshops, story estimation, documentation and release planning
  • Adopt and evolve Friday’s engineering standards and practices, to ensure we have a shared and common approach to development and delivery

Key Skills

To be successful in this role, you will need to have:

  • Extensive commercial experience developing websites and applications
  • Experience writing single page applications using React/Redux, ES6, and modern responsive CSS (e.g. Sass/BEM, CSS Modules etc.)
  • Experience of developing server side web applications using Node.js (e.g. Express, Koa etc.)
  • Experience of unit and integration testing (e.g. Jest/Enzyme)
  • A good understanding of WCAG accessibility guidelines, common issues across web and mobile devices, and how to fix them
  • A good knowledge of git, branching and continuous integration strategies
  • A good understanding of the full web stack including HTTP, REST APIs and performance debugging
  • Be a confident problem solver, troubleshooter and debugger in both development and production environments
  • Ability to convert client requirements into stories and tasks, help define acceptance criteria and provide estimates for delivery.

The Big Plus

In addition to the above, we would be thrilled if you also had:

  • Experience using GraphQL and Apollo
  • Experience of developing applications using Lambda and AWS
  • A demonstrable eye for good user interface design, typography and user experience
  • Experience using any modern content management system (inc. headless mode)
  • Understanding of good agile principles using Scrum and Kanban
  • An active member of the frontend developer community.

About You

Our ideal candidate is someone who is:

  • Delightfully non-ego driven
  • Full of energy and passion for what they do
  • Confident and generous in sharing own specialist knowledge
  • Able to make good decisions by applying both reason and intuition
  • Pragmatic and knows when their code is “good enough” to ship
  • Constantly learning, teaching and challenging their own thinking
  • Able to make others better by consciously teaching and unconsciously inspiring
  • Well organised, with a strong work ethic
  • An exceptional communicator who is able to communicate effectively at all levels
  • Passionate about code, keen to learn and willing to get their hands dirty
  • Collaborative, friendly, ‘hunchy’ with bags of initiative.
