Agentic Engineer (f/m/d)

WHAT WE DO

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.

Sound like your kind of place? Here is what we need from you.

YOUR PROFILE

We're looking for engineers who are excited by agentic and AI-native systems - turning models into products that hold up under real users, real load, and real time. You'll build LLM integrations, agents, and RAG pipelines, treat prompt engineering as a code discipline, and make systems reliable through evaluation, guardrails, and solid testing. Whether you're building your craft or already shaping the AI architecture of a project, we want to hear from you. We hire across levels - here's what each looks like at OH-SO:

Junior AI/Agentic Engineer

You're building your engineering craft - curious about why and how things work, not afraid to get your hands dirty, and eager to grow. You implement from clear briefs - LLM integrations, prompt scaffolding, RAG components - and write the tests and evaluations that keep them honest, comfortable using AI coding tools (Claude Code, Cursor, Copilot) under supervision. You want to understand why and how we're building things, ask what the purpose and the constraint are before you start, and your work is reviewed before it merges.

AI/Agentic Engineer (typically 2-3+ years)

You own an AI feature end-to-end - an agent flow, a RAG pipeline, an integration across its error paths and guardrails - delivered independently with light oversight. You build evaluation harnesses to prove quality rather than assume it, use AI coding tools autonomously in production, and contribute to the shared AI backbone (the AI-brain MCP and skill library).

Senior AI/Agentic Engineer (typically 5+ years)

You own the AI outcome of a project - you define the integration shape, the multi-agent architecture and orchestration, the evaluation strategy and guardrails, and you write the ADRs that document why. You're the technical credibility in the room, contribute patterns and skills back to the shared backbone, and mentor the engineers around you. You use AI to define new ways of working, and you think in long runtime: the AI landscape will shift underneath the project, so you build for inheritance and replaceable layers. You help us move forward as an organization and you act as an AI evangelist.

What you bring to the table, at any level:

• 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.

The stack you’ll work with:

• 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

Who you will work with

We are a bunch of colleagues originally from similar backgrounds who got tired of how things were usually done and set out to find better ways. That is the whole reason this company exists, and it is still what we are doing.

We are not a place of rockstars and egos. People here ask questions out loud, show rough work without flinching, and would rather help each other get something right than look clever alone. We push each other, in the good way, and we do not take ourselves too seriously while we are at it.

You would be joining that. You’ll work closely with the crafts, designers and strategists, and just as easily with the people steering the projects and the business. There is no wall between you and any of it. Take on the parts you are ready for, and when you want more, a pitch, a client conversation, a bigger call, speak up at the right moment and the door is open.

Smaller team. More ownership. Bigger work.

Digitalagentur, neu gedacht. Wir sind eine AI-native Marketing- und Technologieagentur, powered by WPP — AI-fähige Teams für Strategie, Kreation und Technologie, angetreten, um neu zu definieren, wozu ikonische Marken fähig sind.

Wir arbeiten in zwei Tracks: Experiences — die Ideen, Plattformen und Produkte, die Menschen bewegen und überzeugen — und Systems — die AI-nativen Workflows und Delivery-Modelle, die alles schlank, schnell und skalierbar machen. Wir bauen Tools und Fähigkeiten in jede Kundenbeziehung ein und verdienen uns das Vertrauen zu bleiben — ambitionierte Kunden bleiben, weil sie wollen, nicht weil sie müssen.

Gegründet 2024 mit einer strategischen Minderheitsbeteiligung von WPP, sind wir in Hamburg, Prag, Berlin und München zuhause — mit Zugang zu WPPs globalem Netzwerk von 115.000+ Talenten und 35.000+ Tech-Expert:innen.
