[Hiring] Agentic Engineer @OH-SO Digital

Role Description

We are a startup digital agency, and no two projects, clients, or even days look the same. But all of our days are agentic-first.

• In ecommerce, we build on Shopify and Liquid and Next.js, with custom AWS microservices and apps that take Shopify well past the defaults.
• On the marketing side, we build highly customised sites in Next.js and React, with careful design and animation and a real focus on how the page performs and feels.
• In automotive and other industries, we build full platforms, AI tools, and integrations, from stock-car locators to configurators and a lot more.
• Across all of it, we bring AI into the work through our own products.

Here nothing will be fixed. You will work across changing projects and settings, on long builds that run for months and shorter spikes to figure out how a business can actually use AI, and you will help us rethink how agency work is done.

Qualifications

• Experience building with LLMs or AI systems in production - integration, agents, RAG, or similar.
• Strong software engineering fundamentals in Python and/or TypeScript, and confidence designing and working with APIs.
• A habit of treating prompt engineering as a code discipline — with a real understanding of evaluation, guardrails, and reliability.
• A solid grasp of testing and quality: you build systems that hold up under real use, not just in a demo.
• A genuine interest in agentic systems and where the AI landscape is heading - and the judgement to apply it well, not just talk about it.
• Openness to collaborating with cross-functional teams - from designers to strategists - as well as directly with clients.
• You’re enjoying being part of a team, not a remote desk which prefers to work in isolation most of the time.

Requirements

• Junior AI/Agentic Engineer: Building your engineering craft, curious about why and how things work, eager to grow, implementing from clear briefs, writing tests and evaluations, comfortable using AI coding tools under supervision.
• AI/Agentic Engineer (typically 2-3+ years): Owning an AI feature end-to-end, building evaluation harnesses, using AI coding tools autonomously in production, contributing to the shared AI backbone.
• Senior AI/Agentic Engineer (typically 5+ years): Owning the AI outcome of a project, defining integration shape, contributing patterns and skills back to the shared backbone, mentoring engineers, using AI to define new ways of working.

Benefits

• The stack you’ll work with includes:
• Languages & core: Python and/or TypeScript, strong RESTful API design.
• AI & agents: LLM integration, RAG and vector databases, agent frameworks, multi-agent orchestration, MCP and agent infrastructure, prompt engineering, context and memory management, evaluation and guardrails.
• Testing & quality: automated testing, evaluation harnesses, observability and monitoring of AI systems.
• Cloud & infrastructure: cloud platforms, containerisation with Docker and Kubernetes, CI/CD (infrastructure-as-code with Terraform a plus).
• AI tooling: Claude Code, Cursor, Copilot, Google Antigravity.
