Senior / Principal Applied AI Engineer (UK / Europe, Remote)

About GoCharting GoCharting is a web-native charting and trading workflow platform with institutional-grade orderflow and DOM tools - footprint/cluster charts, volume/market profile, cumulative delta, imbalance charts, DOM trading. We are the only platform that delivers these capabilities fully on the web. We are differentiated as the leader in the professional orderflow niche. PE-acquired and funded in 2025, profitable, 3M+ registered traders globally, with a mandate to scale 10x over 4 years. The Role We want AI to be a genuine force multiplier across GoCharting - first inside the company, then inside the product. This is the person who builds that: AI agents, agentic workflows, and the pipelines and harnesses that wire large language models into our real systems and, over time, into the product 3M+ traders use. You will build from scratch when the problem demands it and integrate the best existing platform when it doesn’t - and you’ll know the difference. Early on the weight is internal: removing real toil across engineering, support, and growth by wiring LLMs into the tools we already run and shipping agents that actually work in production. As that muscle matures, the weight shifts toward the product - bespoke, build-heavy AI capabilities in the trading terminal and developer experience, built hand-in-hand with Product and Core Platform Engineering. This is a hands-on engineering seat, not an advisory one. You write and own production code, you put evaluation and observability on everything you ship, and you run autonomously in a lean team. You report to the COO and partner closely with the CTO, the Head of Product, and Head of IT & Security. In year one, success looks like a set of AI systems live in production - measured, reliable, and paying for themselves in time saved or product value created. What you'll do Build AI agents and agentic workflows from scratch - agent loops, tool-calling, structured outputs, planning and state, retries and guardrails - and the orchestration/harness layer on top of existing LLM providers via API (Anthropic, OpenAI, open-weight models, MCP). You write the agent, not just its config. Ship internal AI automations that remove real toil - e.g. triaged, automated engineering-workflow and pull-request review across the tools we already run (GitHub, Slack, Intercom, Jira), support deflection, and social/market listening - integrating an off-the-shelf tool where the need is commodity, and building bespoke where it isn’t. Build in-product AI capabilities with Product and Core Platform Engineering - bespoke pipelines for the trading terminal and developer experience where no off-the-shelf option fits (this side is build-heavy). You prototype it, then productionize it with the platform team. Own the buy-vs-build call - integrate and measure an existing platform first for commodity internal needs; build or replace it internally when it’s differentiating or becomes cost-prohibitive. Ship outcomes, not architecture debates. Put evaluation, observability, and cost guardrails on everything - golden datasets, eval harnesses, tracing, fallback chains, latency and spend controls. Nothing ships as an unmeasured demo. Operate inside our security and AI governance - SOC 2 / ISO track and an approved-tooling allowlist - handling source code, customer data, and product data responsibly. What we're looking for Must-haves: 8+ years of production software engineering , deep in APIs, integrations, and systems - REST, webhooks, OAuth, event-driven and distributed systems - with integrations you owned end-to-end (not “called an API once”). 2–3+ years building and shipping production LLM/agent systems from scratch against provider APIs - you have personally written the agent loops, orchestration/harness, tool-calling, structured outputs, guardrails and RAG, running for real users. Assembling an off-the-shelf agent builder does not count on its own. Hands-on, fluent in Python and TypeScript - you write and own production code. This is a builder seat: not no-code/low-code wiring, not “vibe coding”, not advisory. Evaluation and observability discipline - golden datasets, eval harnesses, tracing, cost/latency guardrails, graceful failure. You treat “does it work, measurably?” as the job, not an afterthought. Deep LLM-API fluency (Anthropic/OpenAI/open-weight), MCP, agent frameworks - and fluency using AI coding tools (Claude Code, Cursor) to move fast. Cloud and delivery : AWS and/or DigitalOcean, Docker, CI/CD, SQL/Postgres. Sharp buy-vs-build judgment and security/data-governance maturity - you don’t pipe production or customer data to arbitrary endpoints. High autonomy in a lean team - you find the problem, design the solution, and ship it. EU/UK timezone , with solid overlap with Central European hours. Nice-to-haves: Go experience - a strong plus for building and productionizing alongside our platform engineering team (not a gate). Fintech / trading / market-data domain, or genuine experience as a trading-platform user. Open-source contributions to AI tooling (LangChain, LlamaIndex, vLLM, DSPy, or similar). Production RAG and vector databases; code-generation, transpilation, or developer-experience tooling experience. Prior forward-deployed / applied-AI / internal-enablement engineering role. Logistics Location Europe (EU/UK) - fully remote; must overlap Central European working hours Employment type Full-Time (via Employer-of-Record in your home country) Travel Light - occasional team/leadership meetups Start date ASAP Reports to President & COO
