How do we work?

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 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.

What We Offer Our UK Employees

  • Holiday - It is important to us that you take some time for yourself to do the things you love, recharge and refresh, so we offer a holiday allowance of 25 days + bank holidays + Christmas closure (usually 4 days).

  • Flexible working - We are a fully flexible working company and support people working from home and remotely when traveling - 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.

  • Travel cards - London travel can be costly so transport to the office is on us! We will provide you with an annual Oyster card for the zone you live in or a monthly travel allowance if you live outside of London and use public transport to get to the office.

  • Pensions - We want you to feel like working at Formidable is contributing to your future, not just your career, so we will match 4% of your employee contribution with 4% to your pension.

  • Private medical insurance - We like to do what we can to give our Formidables peace of mind internally and externally, so we provide full private MHD [medical history disregarded] cover with AXA PPP, including dental and optician add-ons (this can be extended to spouses and children too and Formidable will pay 75% of their premiums), as well as life cover & critical illness cover.

  • Home office stipend - Upon joining Formidable as a permanent employee, you will have access to a stipend of £/€1,750 to help provide a comfortable working space at home.

  • Health & wellness bonus - Health and wellness can come in all different forms so to support you in choosing what works, we give you an annual £1,250 bonus to spend on what is right for you.

  • 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 specialists 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 leveling 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)

  • Visiting HQ - Formidable was launched in Seattle so once a year we all descend on Formidable HQ for FormidaGathering - it’s quite a week away!
