Vision

Mission

Challenge

&nbsp; &nbsp; &nbsp;

On average, 20% of our lives are spent in poor health, costing the UK upwards&nbsp; of £100 billion* annually —more than half of what the NHS spends each year.<br><br>At Thriva, our mission is to increase healthspan—the years we live in good health—so that we, both as individuals and as a society, can make the most of our present and future.&nbsp;<br><br>&nbsp;At Thriva, we believe that proactive, preventative lifestyle approaches are essential to achieving this.<br><br>But it can be hard to know where to start. We often don't have the information or support we need to optimise our health proactively.
<br><br>&nbsp;We want to take the guesswork out of managing health. We focus on putting quality health data in your hands and give you access to technology, innovation, and clinical expertise that makes interpreting this and knowing what action you should prioritise easy.<br><br>*Analysis by Institute for Public Policy Research: Healthy Industry, Prosperous Economy 2024<br>

A preventative approach

We go the extra mile to make sure customers are supported and cared for. <br>  &nbsp;We take the development and welfare of others seriously. And we take the time to share feedback regularly.  <br>  &nbsp;We look after ourselves. We take time off when we need it, and we’re comfortable sharing if we’re struggling. The team can’t thrive if we’re not thriving&nbsp;

Truly Care

The motivation to improve trumps the need to be right.&nbsp;Strong opinions, weekly held. <br>  If we make a mistake, we look at what we could have done differently - before looking at external factors.  <br>  &nbsp;We’re open in sharing learnings, mistakes, and shortcomings with others - to help us learn and grow.&nbsp;

Stay humble&nbsp;

We go all out to make sure our customers and team are as excited as we are, and we bring them along with us.&nbsp; <br>  &nbsp;We communicate a lot to make sure  we're pulling in the same direction.&nbsp;  <br>  &nbsp;We create a shared vision of the future and get others excited about how to achieve it.

Meet Our Team

<html><head></head><body><div>
<h2>Meet our product team!</h2>
<p>We have a small but mighty product team that works across both our direct-to-consumer and B2B products. Working in the healthcare space provides interesting product challenges but also great rewards when the products you build have a positive impact on the lives of our customers. We work very collaboratively with engineers, designers, and product managers, taking shared ownership of outcomes. As a small team, we value people who move work forward proactively, make sensible decisions quickly, and communicate openly when something is blocked.</p>
<h2>Why work with us</h2>
<p>At Thriva, we’re on a mission to close the gap between lifespan and healthspan. We help people live better now, and for longer, through proactive at-home testing, clinician-reviewed results, and personalised, evidence-backed actions. We are already leveraging cutting-edge AI capabilities to redefine what a personalised health journey can look like, combining clinical rigour with intelligent, adaptive systems that generate more precise insights and enable deeply personalised guidance at scale.</p>
<div>You’ll work alongside humble, impact-driven people building something meaningful in a space where getting it right matters. Our B2B platform powers our direct-to-consumer product, so engineers work across systems and collaborate widely to solve challenging problems.</div>
<div>We bias toward action over perfection. When things are unclear, we create momentum through drafts, spikes, and early pull requests. You’ll be trusted to work autonomously by using data, breaking down ambiguity into clear next steps, and making pragmatic, reversible decisions while keeping the team aligned.<br><br></div>
<div>We are actively investing in AI-driven development workflows and modern tooling. We see AI as a force multiplier for thoughtful engineers, helping us experiment faster, unlock new product capabilities, and focus our time on the highest-value problems. We’re excited to work with people who are curious, adaptable, and motivated to stay at the forefront of modern software development.</div>
<div>&nbsp;</div>
<h2>Our current Tech stack</h2>
<ul>
<li><strong>Ruby on Rails</strong> - powers our APIs and some of our internal frontends</li>
<li><strong>Typescript, Vue3 and Nuxt</strong> - for our frontend applications and websites</li>
<li><strong>Tailwind</strong> - for our CSS</li>
<li><strong>RSpec, Jest, Checkly and Playwright</strong> - for testing</li>
<li><strong>Storybook &amp; private NPM modules</strong> - for managing our UI component library</li>
<li><strong>AWS, Docker and Kubernetes</strong> - for most of our infrastructure</li>
<li><strong>Postgresql, RabbitMQ and Redis</strong> - for data and async messaging</li>
<li><strong>Terraform</strong> - defining infrastructure as code</li>
<li><strong>GitHub</strong> - for source control and continuous integration</li>
<li><strong>React Native</strong> - for our mobile application</li>
<li><strong>GraphQL</strong> - a backend for frontend for some of our frontend apps</li>
<li><strong>AWS Bedrock, Langfuse, and RubyLLM</strong> - LLM infrastructure</li>
</ul>
<h2>About you</h2>

<li>You have experience designing and evolving backend architectures in production, including work with Ruby on Rails</li>
<li>You write modular, well-tested, and maintainable code, and are comfortable working within established codebases</li>
<li>Whilst your core expertise is in backend engineering, you’re comfortable working across the stack, including making frontend changes when needed, and you enjoy collaborating closely with frontend-focused engineers</li>
<li>You enjoy working in a cross-functional team where engineers contribute to shaping solutions, not just implementing tickets.</li>
<li>You’re comfortable taking ownership of problems that aren’t fully defined, using data and judgment to decide the right next step.</li>
<li>You like to find solutions, not just raise issues, proposing clear next steps, understanding trade-offs, and helping the team move forward.</li>
<li>You actively explore modern AI-assisted development workflows and see them as a way to increase your effectiveness and the team’s impact.</li>
</ul>
<h2>In return, we will ensure you have:</h2>

<li>Annual learning and development budget</li>
<li>£100 Thriva credit every month</li>
<li>A well-equipped central London office in Old St with plenty of snacks, drinks, and coffee</li>
</ul>
<h2>What happens next</h2>
<div>Once we receive your application, we will review it as quickly as possible and reply to you with the next steps. We get a lot of applications, and sometimes it’s just not the right match. Because we get so many CVs, we cannot provide you with individual feedback.</div>
<div>&nbsp;</div>
<div>If we move on to the next stage, we will arrange a brief 30-minute intro call where we can tell you more about us and chat through what you are looking for. This is a chance for you to ask as many questions as you like. From there, and depending on the role, there will be a couple of other stages.</div>
<div>&nbsp;</div>
<div>We understand that applying for a new job takes a lot of work, and we really value your time. We are excited to read your application!</div>
