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

Your work will help create high-quality datasets that enable the development and improvement of our preventive healthcare technology. This role requires a high level of integrity, strong attention to detail, consistency, and the ability to work efficiently with large volumes of data.

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

Label and quality-check images/audio using our annotation tools.
Follow clear guidelines and examples to label consistently and accurately.
Flag unclear cases or data issues, and escalate to the team when needed.
Help improve our labelling instructions by reporting edge cases and tool friction.

Requirements

Experience to data analysis, data science, medical imaging or data annotation.
High attention to detail and consistency; you enjoy structured tasks.

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).

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.

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.

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.
