Senior Software Engineer



Software Engineering
London, UK
Posted on Wednesday, June 12, 2024

Unmind is the leading workplace wellbeing platform, on a mission to create mentally healthy workplaces where employees can flourish.

Grounded in science and built for enterprise, we drive people-first performance at some of the world’s biggest brands, including Uber, Major League Baseball, NHS, Disney, Standard Chartered, Mediacom and British Airways.

Our services support the whole organisation with data-driven performance insights for leaders, training for managers, wellbeing tools for all employees, as well as access to a global network of accredited mental health practitioners.

Our internal standards are as high as those of our clients. We’re an ambitious VC backed software business on the exhilarating 10-100M phase of our growth journey. It’s hard and rewarding work and we’re determined to be our very best case study along the way.

Unmind believe high performance will hinge on the powerful harmony between our relentless drive for results and creating an environment that elevates our people's wellbeing. This wouldn’t be possible without a dedication to our core values:

  • Be Human
  • Grow Your Mind
  • Innovate at Speed
  • Inspire & Impact

To learn more about what these values mean to us, please visit our careers page.

Our DEI commitment

We strive to build a workplace that celebrates our differences, where every Unminder feels included, equal, seen and heard. This is true regardless of your age, race, gender identity, religion or belief, marital or parental status, disability, neurodiversity, or sexual orientation.

We’re proud of our culture, but not smug. So if there’s anything we can do to make the hiring process more accessible, just let us know when you apply, or email

The Role – Senior Software Engineer

We are looking for an experienced Senior Software Engineer. You’ll be driving the expansion and enhancement of our integrations with client’s HR systems, ensuring a seamless onboarding process for our clients and users. Your expertise in developing robust, scalable solutions will be instrumental in delivering a top-tier product that meets enterprise needs.

In this role, you’ll get to:

  • Collaborate with a Technical Product Manager and Staff Engineer, contributing ideas as well as translating complex business needs into actionable solutions
  • Work alongside other engineers to architect, design, and implement solutions that are scalable, reliable, and align with the technical direction of the product
  • Identify lean solutions and guide the team to find the right balance between technical excellence and shipping value to our users and clients
  • Own existing (and future!) features and systems - ensuring they are covered by monitoring, automated alerting and tests at the appropriate level
  • Represent your team’s domain in the wider engineering forums - contributing to shaping our technical direction, surfacing (and optimising) benefits to the developer experience and achieving engineering’s strategic goals

Skills and Experience

We encourage you to remove education from your CV upon application as qualifications are not a driving factor in our decision making and we are committed to tackling educational inequality. We firmly believe that no one is the finished article and that there should be learning in every role you do. However, some experience in the following is important for this position:

  • Product experience with Typescript, in a backend environment (Node.js), at a senior level
  • Experience with SQL, and ideally optimising queries against large datasets
  • Experience with other parts of our stack (React, AWS, Terraform) or a willingness to learn
  • Familiarity with authentication mechanisms, such as working with JWTs, OAuth
  • Passion for delivering impactful solutions for our users and clients. You wield tech debt strategically in order to help the team ship quickly and make pragmatic tradeoffs.
  • Comfortable operating in ambiguity (we’re a startup after-all) - remaining open-minded despite uncertainty and viewing change as an exciting opportunity to learn and grow


At Unmind we believe in having a whole person approach and we hope that our benefits enhance the lives of Unminders, helping them be happy, healthy and fulfilled. You can see the full list of our benefits on our careers page, but they include:

  • Private Medical Insurance for you and your family
  • Unmind Equity scheme
  • Generous gender neutral parental leave
  • 25 days annual leave plus your birthday day off and 2 celebration days
  • Flexible working, including flexible use of Public Holidays and 3pm finishes on Fridays June-August
  • Hybrid working from dog-friendly Central London office (1 team day a week)
  • £1,000 annual learning budget with 2 days learning leave
  • Monthly ClassPass Subscription
  • Financial wellbeing support via Bippit
  • Access to the Unmind platform, including Talk - book free, weekly sessions with a therapist or coach
