About 4admin

4admin automates the worst admin in UK financial advice. Letters of Authority - the paperwork that lets an adviser act on a client's pension or investment - cost firms weeks of chasing providers, extracting data from PDFs, and rekeying it into CRMs. We automate the whole chain: LOA submission, provider chasing (email and AI phone calls), document extraction, and structured push into the CRMs advisers actually use.

We're a five-person team working with several of the UK's best-known wealth management and IFA firms. We're SOC 2 Type II and ISO 27001 certified - a small company with an enterprise-grade security posture, because our clients demand it.

The role

You'll work directly with the CTO (co-founder) shipping the core product. This is not a ticket-factory job: you'll scope problems, build them, ship them to demanding enterprise clients, and see the feedback land the same week.

What you'll actually do

• Build and improve features across the product: submission workflows, document extraction, chasing automation, CRM syncing, MCP servers and chatbots
• Build and maintain integrations with third party tools
• Work on and evaluate LLM-powered pipelines: structured extraction from provider documents, transcription-driven workflows, AI chasing
• Own work end-to-end - spec, build, ship, monitor, iterate
• Help maintain our reliability and security posture (we operate under SOC 2 / ISO 27001 with FCA-regulated clients)

The stack

• Python (Flask) backend
• Azure : App Service, Cosmos DB, Blob Storage, Key Vault, Azure OpenAI, Front Door + WAF
• Databricks for analytics and reporting
• TypeScript/Javasript on the front end
• Claude Code/Codex use for reviewing code changes and pull requests

What we're looking for

Must have

• Roughly 2-4 years shipping production software - or you're earlier in your career with strong evidence you can (side projects, open source, work you can walk us through)
• Strong Python
• Real cloud experience, Azure preferred (deep experience elsewhere plus appetite to go deep on Azure also works)
• AI-assisted development as your default way of working - Claude Code, Cursor, Codex, or similar agentic harnesses - and you can show us how you use them well
• Comfort with third-party API integrations: REST, OAuth, webhooks, and the reality of flaky vendor sandboxes
• Clear written communication - we're fully remote and async-heavy

Nice to have:

• Cosmos DB or other NoSQL in production
• LLM pipeline work: prompt design, structured outputs, evals
• Databricks / Spark
• Document processing (PDF extraction, OCR)
• Fintech, wealth management, or other regulated-industry exposure

How we work

• Fully remote, async-first, small and senior. You get real autonomy, direct access to the founders, and possibly direct exposure to clients.
• AI-native across the whole business - engineering, support, ops. We expect you to leverage AI aggressively and well, and we'll teach you how we do it.
• We ship fast to enterprise clients. Quality and pace - not one or the other.

Process

1. Intro call (30 min)
2. Technical session - pairing on a real-shaped problem, using your AI tooling of choice. We care as much about how you work as what you produce.
3. Founder conversation
4. Offer

This role is only open to candidates based in the UK, or EU. Please do not apply if you are from elsewhere.
