Principal Platform Engineer

📋 Job Overview

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.

🏢 About Neko

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.

🎯 The Role

This is a 0→1 build. You'll own the architecture, build and rollout of Neko's internal AI developer platform, shaping how our engineers design, ship and operate software through agentic, AI-assisted workflows. It's a hands-on technical leadership role. You'll be the person setting long-term direction for AI agents, tooling and the systems underneath them, while also doing the work. The expectation is that what you build gets used across teams and meaningfully changes how engineering happens here.

✅ Key Responsibilities

• In the first 6 months, deliver a clear architectural direction for the platform
• Ship initial components and adopt them by early teams
• Measure improvements to developer speed, reliability and autonomy
• Drive genuine organic adoption across engineering, driven by value not mandate
• By month 12, shift toward agentic, engineer-led development workflows
• Scale the platform beyond pilot groups to multiple teams
• Define clear ownership models for agents, tooling and supporting systems
• Define long-term architecture and move toward maturity

📌 Required Qualifications

• Proven experience building and shipping an internal developer platform, hands-on, not advisory
• Strong track record leading agentic or AI-assisted development work that engineers actually use day-to-day
• Real backend engineering depth with production systems, recent Java or C# strongly preferred
• Experience rolling out platform tooling to 20-30+ developers with meaningful adoption
• Expertise with workflow engines such as AWS Step Functions, Azure Durable Functions, Temporal, Conductor or Dagster
• The ability to drive change through influence and credibility, not positional authority
• 10-15+ years of engineering experience with substantial platform ownership

⭐ Desirable Experience

• Full-stack exposure, though backend depth is the priority
• Background in product-led SaaS or organisations with strong internal developer tooling culture
