Software Developer; Product Engineer

Konfidant Remote, UK or Europe (within 2 hours of UK time)

Konfidant is the consumer intelligence platform from Kokoro Global, the award-winning consumer insights agency. Kokoro Global has been named Agency of the Year three times, won Best Place to Work at the MRS Awards, and works with clients from startups to household names like BT and Sainsbury's.

Brand and agency teams use Konfidant for consumer optimism intelligence and self-serve insight from more than 22,000 survey questions. The platform is live, and AI is at the heart of what comes next: making rich consumer data something teams can explore in natural language, with Konnie, our AI assistant. Think ChatGPT meets market research. We need a talented engineer to help us build it.

We're looking for a Software Developer to join the small, technical team building Konfidant. We call the role Product Engineer: you'll own features from idea to customer, not just the code. It's a systems-level role for a generalist who understands how frontend, backend, databases, caches, cloud resources and deployment all fit together.

You'll work across the full stack: the product experiences our customers use every day, AI features built on agent orchestration and vector retrieval, and the infrastructure that ties it all together. We value high-level architectural thinking over knowing every line of code.

• Architect and build features end to end across the full stack
• Own core areas of the platform, and bring Konnie into more of the product
• Build AI-native features using LLMs, agent orchestration and retrieval over structured and unstructured data
• Develop and maintain vector embedding search and retrieval systems
• Work with real survey data at scale (Click House, Qdrant), and notice when a number looks wrong
• Work with cloud infrastructure, databases and caching layers
• Take ownership of your feature areas with real autonomy
• Ship quickly, learn from users and iterate
  
  Help define how we use AI across the product and in how we build it
• Collaborate closely with our product designer, QA engineer and engineering team to ship quality software

• A proven track record of shipping production software in a professional role, including features you have owned end to end. This isn't an entry-level role, but we care about what you’ve built, not how many years you’ve been doing it
• Strong systems thinking; you understand how frontend, backend, APIs, databases, caches, queues, CI/CD pipelines and cloud deployment fit together as a whole
• Experience with some or all of:
  React, Next.js, Node.js, Prisma ORM, cloud platforms (Azure preferred)
• Comfortable writing SQL; experience with analytics databases such as Click House is a plus
• Familiarity with vector databases, embeddings or search infrastructure is a big plus
• Proficient with AI-assisted development tools (Claude Code, Codex or similar), and rigorous about checking what they produce
• High agency and self-motivated: you thrive with autonomy and take ownership of your work
• Comfortable working with designs in Figma
• Excellent communication skills and fluency in English
• Based in the UK or Europe, within 2 hours of UK time (GMT/BST), with the right to work where you are based

• Competitive salary: £70k to £90k dependent on experience (€70k to €90k if you are based in Europe)
• Generous holiday allowance (UK): 28 days plus Bank Holidays and your birthday off!
• Wide variety of employee benefits (UK): social team, pension, life insurance, income protection, dental plan, EV and cycle to work scheme, eye care and flu vouchers to name a few!
• Equipment: you’ll receive a fully set-up Mac Book Pro and any additional tech required for your work
• Fully remote with flexible working (option to work from…
