Own the systems underneath Caplia: our APIs, MCP and CRM connectivity, data pipelines and the infrastructure that lets the platform scale securely across thousands of companies.
UK Full-time Hybrid
Why this role matters
Caplia sits between companies raising capital and the organisations backing them, and it plugs into the tools they already use. You'll build the layer that makes that connection fast, reliable and secure.
What you'll own
- 01 Platform APIs The APIs behind the product and every integration we ship.
- 02 Connectivity CRMs, data rooms and customers' own agents, over REST and MCP.
- 03 Data and scale Pipelines, performance and reliability as volume grows.
- 04 Security at every layer Encryption, access control and auditability built in from day one.
What you'll bring
- You've designed and run production backend systems
- Strong in API design, databases and cloud infrastructure
- You think about security, reliability and scale early
- Comfort with ownership in a small, fast team
Nice to have
- Experience building integrations or developer platforms
- Exposure to MCP or agent tooling
How we work
- Structure over fragmentation. Clarity over noise. Evidence over instinct. Speed with care.
- Caplia is private intelligence for the early-stage ecosystem. Accelerators, funds, angels, early-stage banks, startup awards and founders use the Caplia platform, and Phronel, the private AI agent behind it, to manage company discovery, evaluation and support.
