Department/Project Description

Seeking a Mid-Level Software Engineer to join the Core Compute Team. The team is responsible for the backend microservices and orchestration logic managing virtual machines across the data center fleet. In this role, you will refactor legacy and modern control-plane codebases to ensure full compatibility and high performance on the new ARM server fleet (NVIDIA Vera).

We are a senior engineering team. We are hiring a backend engineer for our client, a European company that builds AI tools for creators. You will join their product team long term.

The team ships fast. New image and video models reach users within days of release, and engineers are expected to shape what gets built, not only how. You will work directly with their product and engineering people.

What matters most to us
- You have built a product for creators or designers: a design tool, a creative marketplace, a photo, video or audio app, a generative AI platform or something close to it
- You think about the person using the product. You question a feature when it does not serve them and suggest a better one
- You use creative or generative tools yourself and have opinions about what makes them good or frustrating

What you will do
- Build and scale backend services for the lifecycle of AI generations: image, video, audio, 3D
- Run long, resource-heavy generation jobs reliably, with queues, retries and resumable steps
- Bring new models into the product quickly and turn their outputs into features creators actually use
- Work with AWS (EKS, S3, Lambda), Kafka or SQS, gRPC or GraphQL

You should have
- 5+ years of backend work, ideally in Go. If you come from a creator platform and work in another language, apply anyway and tell us how fast you would pick up Go
- Experience owning parts of a production system end to end
- Fluent spoken English for daily work with the client team

The engagement is full time, 40 hours a week, long term. Your working day must overlap with Amsterdam time. Individual engineers only, no agencies.

How we hire: a call with our CTO about your product work and your code, then a call with the client's team. Both are live, with screen share and without AI assistants.

To apply, open your application with a link to a creator or design product you helped build and one sentence on what you owned in it. Applications without it will not be read.

 Tech Lead / Python AI Engineer / Engineering Lead / AI Architect.

Ideally, we would like to find someone based in Western Ukraine.

Across our practices, AI experimentation is organic: agents and accelerators get prototyped, they work, and they find their way to the teams who need them.

Working is not the same as dependable, tested, hardened, properly deployed, and fit for a regulated client. Closing that distance and turning experimentation into an engineering discipline is the job.

You will build and lead our AI engineering team: you, a Senior Engineer and a DevOps Engineer, and own the path from idea to production across every asset class.

You will work with SMEs within the practices to bring prioritised pilots into products that deliver return. You will be the final technical decision-maker on what ships. Roughly two-thirds of your week will be hands-on: architecture, coding and code review. The rest will focus on direction, hiring and the operating model.
 

Key Requirements

We are looking for someone who:

• Has strong experience building and owning products, rather than only completing technical tasks within outsourcing projects.
• Has 8+ years of engineering experience.
• Has strong Python experience, including production systems where Python was the primary language.
• Has strong Azure expertise and experience with production Azure workloads.
• Has hands-on experience with AI/LLM and agentic systems.
• Has experience taking products or platforms from architecture through production and ongoing operation.
• Has a player-coach background — able to lead engineers while remaining hands-on technically.
• Has strong English and communication skills.

Has experience working with regulated environments and implementing security/governance requirements in practice.

You will not be post-technical in this role.

• Responsibilities
• Own the AI delivery operating model and the path from prototype to production — from intake and qualification through build, hardening and rollout across accelerators and client-facing IP.
• Build and lead the AI engineering team: hire two engineers, set standards, review code, unblock the team and support their growth.
• Work with SMEs across practices to design, build, deploy and maintain applications.
• Personally build, ship and harden agentic solutions and own the assets you oversee.
• Own architecture and production standards across solutions, including solution architecture, infrastructure, model selection and validation.
• Turn governance into engineering through policy-as-code, guardrails, evaluations and release gates running in the pipeline.
• Implement controls suitable for regulated clients without unnecessarily slowing down development.
• Embed AI capabilities across practices by working with automation, application engineering and consulting SMEs to create a path from prototypes to production.
•  
• What Would Set You Apart?
• Claude Certified Architect (Foundations or Professional).
• Microsoft Agentic AI Business Solutions Architect (AB-100).
• LLM or agentic systems already taken to production.
• Experience deploying accelerators or productised IP across multiple clients.
• 
   

Location: Ukraine - preferably the western part of the country.

Budget: Up to €72,000 gross/year
