Formidable is hiring a

Senior Cloud Infrastructure Engineer (London)

London, United Kingdom
Formidable is a boutique engineering consultancy and open source software organization, specializing in React.js React Native, GraphQL, Node.js, and the architecture of large-scale JavaScript applications. We are a team of consultants working together to find holistic and sustainable solutions to challenging software and process problems for our clients. We build products for some of the world’s biggest companies while helping their internal teams develop the skillset to create and maintain thoughtful and scalable systems.

We are looking for a Senior Cloud Infrastructure Engineer to join the Formidable UK team - either based in our London office or remote within the UK. You will help clients build cloud platforms at-scale, assisting in every part of the process, from concept to production. The cloud landscape is continuously evolving, with new tools and services being released daily. You know how to distinguish hype from reality and are comfortable making recommendations that best suit our clients’ needs.

Formidable’s growing platform team has experience with all major cloud providers and you will be comfortable leading teams and mentoring engineers in core concepts like high-availability, scalability, and monitoring. You know architecture is more than just drawing boxes, and are excited to dive in and lead by getting your hands dirty. Our go-to tools for cloud infrastructure are Terraform and AWS, so ideally you’ll know these inside-out. We’re a JavaScript-first consultancy, so detailed knowledge of JavaScript will be a massive bonus so that you can easily communicate with backend engineers when they come to deploy their Node.js applications to your infrastructure.

We make sure our employees get opportunities to grow within Formidable and participate in daily decision-making processes. Our engineers are leaders in the community and frequently speak at key conferences. Working with other Formidables, you are guaranteed to continually cultivate your skill set by staying atop of industry trends and tools.

This role is a full-time position and can be a remote, work-from-home role if needed.

In light of COVID-19, Formidable will continue to recommend that all employees continue to work remotely whenever possible. Currently, Formidable has no plans to require anyone to be physically present in a Formidable or client office.

If you’re interested in joining a collaborative community that supports employees and understands the importance of maintaining a work-life balance, we would love to talk to you!

  • Flexible working - We are a fully flexible working company and support people working from home and remotely when travelling - this means you can pretty much work from anywhere and set your own hours. We only ask that you are available for team and client meetings and can dial in from wherever you are if you are working remotely that day.

  • Inter-office travel - We like our Formidables to get to know each other properly; what better way than a trip to visit and work with other teams around the globe? We will give you £850 annually to cover your travel and accommodation so you can go and work in one of our other locations and get to know the team better. (Pending COVID-19 restrictions)
  • Open source - We have incredible access to a wider community of coding experts who are as passionate about Open Source as we are + an internal ‘Sauce Program’ that enables you to earn extra money for any extra OSS hours you put in.
  • Training & development - You’ll receive unparalleled support from your peers + an all-you-can-eat professional development budget to ensure you can access all that you need to keep growing in your role and levelling up.
  • Collaboration & exposure - We work in a collaborative environment that leads to continuous, organic personal development. You’ll also have exposure to a wide variety of customers, from scale-ups to Fortune 100s.
  • Giving back - We also love to give back to our community - so if you give to charity and want to set this up through payroll giving, we will match your contributions by up to £1000 a year.
  • Feeling peckish?  Us too, which is why we have catered team lunches twice a week + a fully stocked office of snacks and drinks to keep you going throughout the day. (Pending COVID-19 restrictions)

As a true example of how Formidable believes in equity and transparency, we have an “Open Pay” system that is linked to our career ladder. Depending on experience, the salary for this role would likely fall between £75-85k.

How do we work?

Our consultants act as an extension of our customer’s team, embedding themselves in the environment, and adapting to our clients’ requirements and challenges, so they can develop a truly impactful and innovative solution.

We take a lot of pride in both the work we do and how we do it. We love trying new approaches, challenging the norm and we’ll never stop striving to be at our technical best. It comes naturally to both our team and the community we work within to help each other’s growth, share and elevate ideas, and meaningfully collaborate as much as possible. Our people are more than the sum of their parts!

That’s why you’ll get an unusual amount of autonomy — you’re here because you’re brilliant, so we trust you to do your role in a way that works for you. Our high-trust culture is one of the things that makes us so successful, so you do you and we’ll be over here, listening and providing support where needed.
We have two core beliefs here:
1) The very best ideas are born from a community that is collaborative, high-trust and diverse. Creating a development-led culture is key to us so we do everything we can to cultivate knowledge sharing and personal growth within our team. That means your questions never go unanswered, and there will always be someone on hand to work through a problem.

2) People are at their best when they have what they need and we’re committed to providing the best possible working environment. Vegan snacks? Slippers for the office? Want to work from another country to spend more time with your family? We got you!

Inclusion is one of our core values. We don’t discriminate by race, religion, national origin, gender identity, sexual orientation, age, marital status, veteran status, or disability status. We are not offering UK visa sponsorship at this time and hence unfortunately require of our candidates that they have the right to work in the UK without visa sponsorship.
