Job summary

South Pole is looking for an AI Developer to help build the intelligent layer behind our products. You will design, build, and ship production‑grade AI features: LLM‑powered workflows, retrieval pipelines, and agentic tooling that turn large, messy environmental and carbon‑market data into reliable answers.

This is a hands‑on engineering role pitched at a medior‑to‑senior level. We are open to a strong medior developer ready to step up, as well as a senior who can take a vague requirement and turn it into a tested, well‑reasoned feature. What matters is that you understand the why behind your choices – not just how to call an API, but when not to, and how to keep an AI system trustworthy, evaluated, and cost‑aware in production.

Key Responsibilities

• AI Feature Development: Design and ship LLM‑powered features end to end – retrieval‑augmented generation (RAG), structured extraction, summarisation, and agentic / tool‑using workflows.
• Pipelines & Integration: Build robust data and inference pipelines that connect our AI layer to product back‑ends, vector stores, and source systems (AQ, Salesforce, Google Workspace).
• Evaluation & Reliability: Stand up evaluation, monitoring, and guardrails so AI features are measurably accurate, safe, and stable – not just impressive in a demo.
• Performance & Cost: Optimise latency, token usage, and throughput; apply caching, batching, and model‑routing to keep large workloads fast and economical.
• Quality Assurance: Champion rigorous testing and pull‑request discipline to prevent regressions and keep deployments stable.
• Collaboration: Partner with the Tech Lead and product owners to translate business problems into AI solutions, and flag where a non‑AI approach is the better call.

Technical Requirements - Core Stack

AI & Machine Learning

• LLM Engineering: Hands‑on experience building with LLM APIs (e.g. Anthropic, OpenAI, or Vertex AI / Gemini) – prompt design, function/tool calling, and structured outputs.
• RAG & Retrieval: Practical knowledge of embeddings, chunking, and vector search (pgvector, or a managed vector DB).
• Frameworks: Familiarity with at least one orchestration framework (LangChain, LlamaIndex, or equivalent), and comfort working without one when it's simpler.
• Evaluation: Awareness of LLM evaluation, hallucination mitigation, and basic red‑team­ing of AI outputs.

Back‑end & Data

• Back‑end: Strong Python (FastAPI / Flask / Django), with clean, testable, production‑oriented code.
• Database: Solid PostgreSQL – comfortable with relations, indices, constraints, and transactions beyond basic ORM usage.
• Data: Experience handling large, high‑volume datasets and streaming / batch processing.

Systems & Cloud‑Native Architecture

• Cloud: Experience with GCP (Vertex AI, Cloud Run, Pub/Sub) or a comparable cloud platform.
• Event‑Driven Design: Proficiency with queues and Pub/Sub for asynchronous, event‑driven workflows.
• DevOps Fundamentals: Working knowledge of CI/CD workflows and containerisation (Docker; Kubernetes a plus).
• Security: Sound practices around authentication, authorisation, throttling, and handling of sensitive and proprietary data in AI workflows.

Communication Skills

• Proficiency in business English.
• Ability to translate complex technical and AI concepts into understandable terms for non‑technical business colleagues.

Desirable Requirements

• Experience with MLOps / model lifecycle tooling, or fine‑tuning.
• Exposure to front‑end work (React / Next.js) for AI‑facing interfaces.
• Interest in climate, carbon markets, or sustainability data.

The Ideal Candidate Profile

• Proactive Communicator: You are proactive and communicative. In interviews you prefer a conversational approach – walking us through your reasoning and the trade‑offs behind your tech choices, rather than just providing the “correct” answer.
• Pragmatic Problem Solver: You don't just make a model work once; you find the root cause, build for reliability, and know when a simpler, non‑AI solution is the right one.
• Independent: You can take a high‑level requirement and turn it into a fully functional, tested, evaluated feature with minimal oversight.
• Responsible by Default: You care about accuracy, safety, cost, and the trustworthiness of what you ship – a natural fit for a climate company where credibility matters.
