Software Engineer, AI Platform

Job Description:

• You will own how these platforms are built and run: backend services, the developer-facing portal, integrations with internal systems, and the infrastructure underneath.
• The data science team remains closely involved as domain experts and primary internal customers.
• You are the engineer who makes sure what they need actually ships and holds together in production.
• This is a software engineering role first.
• You should understand LLM and agent concepts - how tool calling works, why agent loops behave non-deterministically, how context management affects system design.
• Multi-agent workflows - moving from single-agent execution to coordinated multi-agent systems that can handle complex, long-horizon tasks across business functions.
• Core system integration - deeper connections with Company's operational and commercial systems, so AI agents can act on real data in real time rather than working in isolation.
• Real-time decision support - expanding the platform's role from task automation toward live recommendations and decision assistance in high-stakes operational contexts.

What you'll work on:

• Agent runtime & execution - session state, agent lifecycle management (pause, resume, plan mode), spec versioning, execution safety.
• Auth, security & governance - OAuth integrations, credential rotation, PII controls, prompt injection mitigation, runtime guardrails.
• Platform infrastructure - cost and usage tracking, distributed tracing (OpenTelemetry), scaling across business units.
• Protocol & ecosystem integrations - MCP, A2A, WebSocket-based tooling, multi-cloud file handling.
• Observability & developer tooling - metrics dashboards, debugging infrastructure, the developer portal that internal teams use to build and test agents.

Requirements:

Must-have:

• Strong backend engineering experience in Node.js / TypeScript. Track record of owning services end to end in production - not just shipping features to a spec.
• Comfortable across the stack. Able to pick up frontend work in React when the ticket calls for it, even if backend is your primary strength.
• Solid API design skills. Familiar with authentication and authorisation patterns (OAuth and similar) and production debugging.
• Familiarity with observability practices - logging, tracing, metrics. OpenTelemetry or equivalent experience preferred.
• Conceptual fluency with LLM agent systems: tool calling, context windows, streaming, non-determinism. Enough to make sound architectural decisions in this domain. No ML or model training background required.
• Comfortable with ambiguity. This team is small. You will often decide how something should be built, not just execute a spec.

Nice-to-have:

• Hands-on experience with agent frameworks or protocols (LangChain, Google ADK, MCP, A2A, or similar).
• Cloud infrastructure experience (AWS).
• Background in platform or developer-tooling engineering - building for other engineers as your primary customer.
• Interest in AI security: prompt injection, guardrails, and safe agent execution are real parts of this backlog.
