Tech Lead Developer | Python / C# / Angular | Greenfield & AI Prototyping | £130,000 | Azure | Commodities & Energy | Hybrid, LondonA Tech Lead Developer is required to join a high‑impact engineering group within one of London’s most forward‑thinking commodity and energy trading businesses. This team operates at the intersection of trading, data, AI and rapid prototyping, delivering high‑value greenfield solutions across 12–15 concurrent initiatives.This is a hands‑on technical role with responsibility for leading small project pods (1–2 engineers), shaping solution direction, and building prototypes and production-grade systems across Python, C#, Angular and Azure. You’ll work directly with traders, quants and senior business stakeholders to unpack complex requirements, build proof‑of‑concepts, and turn ambiguous ideas into working software.The environment is fast-moving, exploratory and deeply technical — ideal for someone who thrives in greenfield engineering, enjoys variety, and wants to work on high-value, high-impact projects without people management responsibilities.The TeamThe engineering function sits at the centre of the firm’s data, trading and product innovation ecosystem, responsible for:Greenfield Prototyping — rapidly building new tools, models and workflows from scratchAI Workflow Development — designing and implementing AI-driven decisioning and recommendation systemsProof-of-Concept Engineering — validating new trading ideas, data ingestion methods and modelling approachesFull Stack Application Delivery — Python/C# services, Angular front-ends, Azure cloudData Platform Integration — connecting models, market data, and internal systemsStakeholder-Led Solution Design — working directly with traders and business owners to shape requirementsProjects range from biofuels trading insight platforms, to AI-driven trade recommendation engines, to new data ingestion and modelling workflows replacing manual Excel-based processes.The team works closely with the Head of Engineering, business stakeholders and domain experts to deliver solutions that are both technically robust and commercially valuable.Role Details💰 Up to £130,000 + Benefits 💻 Tech Stack: Python | C# | Angular | Azure | AI/ML workflows | SQL | CI/CD 🏢 Hybrid | Hammersmith | 4 days per week onsiteAs a Tech Lead Developer, you will:Lead small project pods (1–2 engineers) across 12–15 active initiativesDesign, build and prototype full stack applications in Python, C# and AngularUnpack complex trading requirements and convert them into actionable technical designsBuild AI-driven workflows that ingest market data and generate trade recommendationsDevelop greenfield systems from scratch, including data ingestion, modelling and UI layersWork directly with traders and stakeholders to refine briefs, iterate prototypes and validate outputsCreate proof-of-concepts that evolve into production-grade systemsEnsure engineering best practice across testing, CI/CD, cloud architecture and documentationWork within Azure cloud environments, leveraging modern tooling and scalable servicesDeliver high-value projects that materially impact trading, risk and commercial decision-makingRequired ExperienceStrong commercial experience in Python or C# (either is fine; both ideal)Full stack engineering experience with Angular or similar front-end frameworksExperience building greenfield systems, prototypes or PoCsAbility to work directly with business stakeholders and translate ambiguous requirementsExperience with AI/ML workflows, data modelling or algorithmic decisioningStrong understanding of Azure or equivalent cloud platformsExperience working with market data, trading workflows or complex data structuresAbility to lead small project teams without people management responsibilitiesStrong engineering fundamentals: testing, CI/CD, clean code, architectureDesirable ExperienceExposure to commodities, energy or biofuels tradingExperience building recommendation engines or spec-driven workflowsFamiliarity with data ingestion pipelines, modelling frameworks or analytics platformsExperience working in high-ambiguity environments with rapid iteration cyclesKnowledge of AI workflow orchestration or spec-driven developmentExperience with Azure Functions, Kubernetes, or serverless architectures
