# Principal Engineer - Platform at Neko Health

- **Company:** [Neko Health](https://feeny.ai/companies/neko-health)
- **Location:** London, United Kingdom
- **Employment:** full-time
- **Work type:** hybrid
- **Posted:** 2026-10-28
- **Last confirmed live:** 2026-11-01
- **Apply:** https://jobs.ashbyhq.com/neko-health/8849ea48-693c-41f2-b66f-cd838334a7f0

## Job description

Mission Neko is redefining what prevention means, from treating illness when it arrives, to sustaining health before it's ever at risk. Our mission: make data-driven, preventative care accessible to more people, before symptoms appear.

In a single, non-invasive visit under an hour, proprietary technology and direct clinical care combine to deliver personalised, actionable insights. It's a team that thinks in 10x, not 10%. Every role here plays a part in building a world where prevention is the norm, and where your work genuinely helps people live longer, healthier lives.

## Role Purpose

We want our engineers to ship regulated medical software as fast as AI now lets them write it. Our software includes medical device software, holds members’ health data and keeps our clinics running, so every change has to be tested, traceable and ready for an auditor, and that is what makes this problem hard and worth solving.

You’ll build the shared AI engineering platform that makes it possible, setting the architecture and writing much of it yourself: a golden path that makes the best way to build with AI the default for every team, agents that do real engineering work end to end, and a pipeline that proves compliance on every change instead of documents written after the fact. This is a director-level individual contributor role, one of the first Principal Engineer roles in our software organisation, working directly with our Chief Software Officer. You make the key calls on which agents and tools we build or adopt, and you take on the hardest problems across teams, some of which reach clinic devices and the test rigs that recreate a scan room.

What You’ll Deliver in the First 6–12 Months

- 0→1 set the target architecture for the AI engineering platform, including the build or adopt decisions on agents, orchestration and developer tooling
- Ship a golden path for AI-assisted engineering, with shared context, tools and guardrails, that teams choose because it is the fastest way to ship
- Put agents to work on real engineering jobs end to end, such as feature implementation, code migrations, automated review and on-call triage
- Run agents in sandboxed environments with audit trails and clear separation from member health data
- Shorten the path from merged code to production for regulated software: safe releases, fast rollback, and compliance evidence produced by the pipeline
- Measure what changes with numbers engineers trust, such as the share of agent pull requests that get merged and how long a change takes to reach production, and share them openly
- Take on the hardest cross-team technical problems, inside and beyond the platform, where no one has the answer yet

## Minimum Qualifications

- You have designed and built platforms or core infrastructure that other engineers relied on every day, and you wrote a meaningful part of the code yourself
- Deep backend and distributed systems experience in production, with the judgement to make architecture calls in a large, existing codebase
- Your own engineering is AI-first: you use agents for work you used to do by hand, and can explain where they help, where they fail, and what changed in speed and quality
- You take a clear position on hard technical questions with incomplete information, defend it with reasons, and change it when the evidence changes
- Engineers outside your own team changed how they work because of something you built and the technical case you made for it
- Able to work from our London, New York or Stockholm office

## Preferred Qualifications

- Experience with durable workflow orchestration, for example Temporal or Azure Durable Functions, and a clear view on when it is worth it, since long-running agent work has to survive failure
- Work where software meets hardware or physical operations, such as connected devices, edge computing or hardware-in-the-loop testing

## About Neko Health

## Company Overview
- **One-liner**: Neko Health is a healthcare technology company that has engineered a proprietary, data-driven preventive health scan to detect early signs of disease in otherwise healthy individuals.
- **Entity Type**: Private (Funding Stage: Series A)
- **Headquarters**: Stockholm, Sweden
- **Founded**: 2018
- **Founders**: Daniel Ek (Co-founder, also founder/CEO of Spotify) and Hjalmar Nilsonne (Co-founder)

## Core Business
- Primary industry/industries: Healthcare Technology, Preventive Medicine, Clinical Diagnostics
- Target customers: B2C – Health-conscious individuals; B2B Potential – Self-insured employers
- Mission or purpose statement: “To provide healthcare that’s proactive instead of reactive – so that people can live longer, healthier lives.”

## Products & Services
- **[The Neko Health Scan]**: A 60-minute, full-body health check that captures millions of data points across the skin, heart, blood, and circulation using four proprietary devices (Derma, Spectrum, Echo, and Neko Lens). Includes an unrushed consultation with a doctor where results are discussed immediately. The scan is priced at approximately 2750kr (~$260) in Sweden and is designed for asymptomatic, healthy individuals looking for prevention.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed (as of mid-2026).
- **Key Metric**: Total Funding – **$325.1M** (one prior funding round).
- **Notable Investors/Partners**: Backed by “investors who have built and scaled some of the most ambitious technology companies of the last two decades” (individual names not publicly listed on career page). The company has strong ties to the tech and startup ecosystem.
- **Growth Signals**: Over 1,000 employees (more than half in clinical roles). Aggressive expansion with active clinic locations in London, Manchester, Birmingham, Stockholm, and plans for more. Job postings have increased +344.4% year-over-year (as of mid-2026), indicating rapid scaling.

## Competitive Advantages
- **Proprietary Hardware**: All four scanning devices are designed, engineered, and assembled in-house in Stockholm, creating a hard-to-replicate technological moat.
- **Integrated Clinical Model**: Unlike traditional clinics or digital health apps, Neko combines its proprietary hardware with on-site doctors, clinical researchers, and data science under one roof with a low patient volume per doctor ( ~9 members/day vs. 30+ in standard care). This enables a focus on prevention, not just treatment.
- **Data Moat**: The system captures millions of structured data points per scan, allowing for peer benchmarking and longitudinal tracking over years, creating a powerful, network-effect dataset for preventive health insights.
- **Leadership**: Co-founded by Daniel Ek (Spotify) and Hjalmar Nilsonne.

## Strategic Focus
- **Scaling the Scan Room**: Neko is actively testing a second-generation modular scan room platform designed to capture more signals and scale to new locations.
- **Global Expansion**: Opening new clinics across the UK and Europe, with a clear intent to make the service more accessible.
- **Clinical Research & Governance**: Continued focus on validating their devices with clinical studies and building a clinical leadership team (including ex-NHS and Amazon Health executives) to establish preventive care as a formal clinical discipline.

## Why Work Here
- **Mission-Driven**: The company was founded to solve the fundamental problem of late-stage diagnosis by focusing on prevention. The work is presented as having a direct, positive impact on human longevity.
- **Culture & Engineering**: The company actively showcases a deep engineering culture where “clinical insight can become a hardware iteration overnight.” Clinicians and engineers share the same floor, fostering rapid iteration and innovation.
- **Compensation & Benefits**: Salaries are benchmarked via market research. Benefits include comprehensive Medical, Dental, and Vision Insurance, 401K, Paid Time Off, Life Insurance, Disability Insurance, CME Days, and Commuter Benefits.
- **Work Model**: Roles are **on-site** at specific clinic locations. Training for medical roles is fully paid. The interview process is designed to give candidates a feel for the culture and mission.
- **Growth Trajectory**: With 80+ active job postings and triple-digit growth in hiring, the company is in a high-growth phase, offering significant career development opportunities.
