Contract/Permanent - Full-Stack Engineer

Full-time - Remote and London, UK

The Company

Juno inspires more human workplaces by connecting employees to better wellbeing choices. We work with businesses to rethink and improve the wellbeing of employees in over 20 countries, across over 28 cities.

We're looking for someone to immediately step in and help us develop our product. Juno is growing fast, and this could be an opportunity to really make a mark with our challenger status.

Working at Juno means working on something truly meaningful: improving the lives of people at work.

Our mission is simple: to change the way employees experience their work life for the better.

The Role

We are looking for our next key hire, Full-Stack Engineer, on a contract or permanent basis, to continue growing our engineering team. Here, you will take complete, end-to-end ownership of projects across the entire stack. Our ideal candidate has experience building products across the stack and a firm understanding of web frameworks, APIs, databases, and multiple back end languages.

The Full-Stack Engineer would work alongside our Product Owner and our Junior Front-End Developer, and will have a lot of freedom in bringing their expertise to the team and the product. They will report to the CEO directly, and will have an opportunity to build the product up to series A and then build the team from there.

Our Tech

Our application is written in ES6 JavaScript, and our stack includes React, Node, Express, Sequelize and PostgreSQL. 

On the front end we're using React with styled-components, with very heavy use of hooks and exclusively functional components; no Redux, all Contexts.

For the backend we run on Node, serving Express APIs. Across our applications, we use PostgreSQL as our primary data store, with Sequelize interfacing between the database and Express.

Our codebases use ESLint, Prettier, Cypress and Jest to automate testing. We push to GitHub and deploy (continuously) via CircleCI to AWS.

The Responsibilities

  • Work across the full stack, building highly scalable distributed solutions that enable positive user experiences and measurable business growth
  • Develop new features and infrastructure development in support of rapidly emerging business and project requirements
  • Assume leadership of new projects from conceptualisation to deployment
  • Ensure application performance, uptime, and scale, maintaining high standards of code quality and thoughtful application design
  • Work closely with senior internal stakeholder teams including Product, Commercial, Marketing and Operations.
  • Work with modern development methodologies, adhering to best practices and pursuing continued learning opportunities
  • Architect and provide guidance on building end-to-end systems optimised for speed and scale

The Requirements

  • Strong web frontend development experience, e.g. in React; 
  • Strong backend development experience, e.g. in Node.js, Express.js, Sequelize; 
  • Strong experience with AWS; 
  • Working knowledge of infrastructure tooling e.g. Docker, CircleCI;
  • Confident, and able to take initiative in a delivery-focused environment;
  • Preferably experienced in creating a scaled B2B marketplace solution;

What you get

  • Competitive salary and options;
  • Possibility to be on contract or as permanent;
  • Joining a business that is growing fast and on course for Series A in the next few months;
  • A chance to build the team you want, with the resource to make it best-in-class;
  • Freedom to work from wherever you want.

About us

Atos Cerebro is the full-stack engineering division of Atos. We’re a cross-skilled team of product, design, engineering and data experts. We help our clients build, deliver and support digital products and services. 

Each dedicated product team is responsible for all aspects of what they are building, operating independently. This not only allows for fast-paced development and pivots, it facilitates passionate, close-knit teams that work closely together to achieve their goals.

Our teams work in close collaboration with our clients and their users. Many of us have experience across a wide range of industries from finance, gaming, retail, government, energy and media to name a few.

Who you are

You enjoy learning about the customer’s pains and gains, and building products which solve real-world problems. You can work autonomously in a small cross-functional team and can communicate well with team members. Equally you are able to effectively contribute to technology decisions across multiple teams. 

You are firmly focussed on delivering business value and results to end-users. Along with this you have a commercial mindset, with demonstrated ability to make fact based trade offs.

You have prior experience building greenfield products for unfamiliar industries. Familiar with the entire software development lifecycle.

Experience working in start-ups or large corporations (ideally both!) is also a huge benefit. 

You can demonstrate a broad knowledge of available modern technologies and like to experiment with finding the best solution for specific tasks outside your core skill set.

What you'll do

You should be able to demonstrate prior professional experience of the following activities that you’ll do:

  • Build UIs using modern tools such as React, TypeScript, CSS-in-JS, Apollo GraphQL, Cypress
  • Build backend services using Node.js, and knowing when to use relational vs non-relational databases
  • Deliver high-quality, well-tested code
  • Communicate with other teams and individuals to plan, coordinate and seek feedback
  • Pitch in where needed as a valued member of an autonomous, cross-functional team
Who you are
  • Enjoy building user-friendly, data-rich JavaScript/HTML/CSS applications
  • Excellent analytical, problem-solving, and troubleshooting skills
  • You have experience deploying production applications (e.g. GCP, AWS)
  • Rave about the benefits that CI / CD has given you in previous projects
  • Experienced with modern JavaScript coding, testing, debugging and automation techniques
  • Care deeply about performance, accessibility and API design
  • Have a high bar for user experience quality

Location restricted
This job is restricted to tax residents of UK, but we detected your IP as outside of the country. Please only apply if you are a UK tax resident.

We're looking for a talented Senior Front-end Engineer, who can set high standards and drive technical delivery forward while being pragmatic and understanding the bigger picture and the context. Despite this role being short-term, you're a strategic thinker and bring a lot of expertise and experience into this collaboration and are great at weighing up the pros and cons of potential solutions and at communicating this to the rest of the dev team, as well as to non-tech stakeholders.

  • Write high-quality code: As Senior Engineer your primary responsibility would be to develop software. You will be expected to produce readable code that scales.
  • Own your work: You will be responsible for the whole process of delivery, from the initial refinement to production deployment.
  • Mentor: You will be expected to mentor more junior developers in a form of pair programming or learning sessions
  • Solutionise together: You’ll work closely with the Product Manager and Product Designer to understand what problem is being solved and why, and brainstorm solutions together - with you owning the technical implementation side. We believe that magical things happen when the squad aligns often and early.
