Type:
Permanent, full-time

Level: Staff IC

We’ve got an AI strategy with two pillars: making our own teams faster, and shipping AI into our platform. Adoption is moving. Funding is in place. OpenAI, Cursor, Claude Code, and Bedrock are all live in some form.

• The AI gateway: a paved way for engineers and product squads to use the AI tools we’ve picked. Consistent auth, logging, fallbacks, and cost attribution.
• Bedrock and Agent Core: lead our adoption. We’re evaluating Agent Core for agentic workloads now. You’ll take it through to production: architecture, cost model, integration with the rest of our AWS estate.
• Cost governance: per-tribe visibility with alerts before the bill, not after. Tied to where the spend is paying off and where it isn’t.
• Evaluation: a standard way to test AI tools and features, and to catch regressions when models change underneath us.
• Safety: prompt injection, PII, output filtering, audit trails. Pragmatic, proportionate to the risk, not bureaucratic.
• Adoption: building the platform isn’t enough on its own. You’ll work with EMs and staff engineers across all five tribes to make sure it gets used, and the patterns we learn get spread.
• The AI Guild: a cross-tribe group that decides what we adopt, what we retire, and what’s worth experimenting with next. You’ll run it.

Define what good looks like for internal AI tooling (cycle time, defect rate, time saved) and for product AI features (quality, latency, cost per request, customer outcome).

• AI gateway in production, used by at least one internal tool and one product feature.
• Cost dashboard in production. EMs can see what their tribe is spending.
• Agent Core and Bedrock evaluation done. A clear go/no‑go with production evidence behind it.
• First evaluation suite running against real AI features.
• AI Guild meeting regularly with people from all five tribes turning up.

• All product AI features go through the gateway. No squad is rolling its own.
• Every team shipping AI uses the standard eval pattern.
• AI spend is predictable and tied to value. Not necessarily lower; governed.
• Measurable cycle‑time gains on at least two engineering workflows we can attribute to internal AI tooling.
• Rapid
  
  AI use cases shipping through the platform.

• AI is a normal engineering capability, not a special programme. New features take days to wire up, not weeks.
• We can swap models without rewriting product features.
• AI cost, latency, and eval data show up in engineering decisions the same way DB performance does today.

• You ship. You write code, dashboards, and runbooks that other engineers use. You’re not someone who’ll spend three months on a strategy deck.
• You think in platforms. You build the version that works for everyone, not a bespoke solution for each squad.
• You can hold a room. Staff engineers in the morning, a VP in the afternoon. You can explain the same trade‑off to both without losing either.
• You’ve changed your mind about AI before, based on evidence. You can tell us about a use case where AI didn’t pay off.
• You know the unit economics. You can tell the difference between “AI is expensive” and “this pattern is expensive, here’s a cheaper one”.
• You understand the benefits and the risks of an AI first approach running at scale.

• You know Bedrock in production. We’re an AWS shop and Bedrock is our strategic substrate. You should already have the IAM, VPC, throughput, and observability scars.
• Agent Core experience is a big plus given where we’re going.

• Agent Core in production, or a comparable agent runtime (Lang Graph Platform, Vercel AI SDK, in‑house)
• Built or operated an LLM gateway
• Built or run an eval framework in production
• Owned cost governance on a meaningful AI workload
• Shipped customer‑facing AI and handled the security and legal conversations that come with it
• Run a Cursor or Copilot rollout and know what made adoption stick
• Background in Platform, Dev Ex, ML Platform, or Applied AI. We’re open.

• 5 engineering tribes (Money, POS, Business, Data, Platform), ~120 engineers.
• Offices in Norwich and Sofia.
• AWS‑native. Git Lab. Slack‑first.
• OpenAI, Cursor, Claude Code, are in real use.
• AWS Rapid
  
  AI funding is unlocking customer‑facing AI work.
• UK fintech SaaS scale‑up. Sales‑led, cashflow‑conscious, willing to invest where the upside is real.

You’ll report directly to me. Clear remit, exec sponsorship, the air cover to make decisions stick.
