HEY THERE
What if the tools you build didn't just help one team, but unlocked the potential of an entire company?
At Yazio, we're looking for a Senior Internal Tooling Engineer to turn repetitive work into intelligent systems. You'll help shape how AI is used across the business, building production-ready tools that empower teams to move faster, eliminate manual work and focus on what matters most.
If you're excited by solving real problems, shipping AI-powered software/features that create measurable impact and owning your work from idea to production, this is where your expertise will have its greatest impact.
This role is 100% remote and open to candidates based in Germany, Spain, Portugal or the U.K.
YOUR MISSION
Design and ship the internal tools, automations and platforms that remove bottlenecks across Yazio, owning the full stack from web apps to distributed, async job processing systems
Drive discovery with internal stakeholders, marketing, localization, user success and others, to uncover their biggest bottlenecks and ship tailored solutions that eliminate manual work
Build and scale our AI driven systems, such as our Creative Automation System (automated creative uploads and ad creation) and Content Generation System (production grade AI translations), bringing the latest AI capabilities, LLMs, RAG and agents, into production
Apply cutting edge AI to how you work, using agentic coding and AI assistants to build and ship fast while maintaining a high bar for quality and safety
Make key technical decisions and design robust, distributed and maintainable architectures, including queuing, asynchronous processing and the reliability our automations depend on
Own your work end to end, from scoping and stakeholder alignment through delivery, measurement and iteration, anticipating downstream effects and removing roadblocks proactively
Raise the bar for the team, mentor others in software design and process automation, document clearly and help shape how Yazio adopts new AI technology
YOUR PROFILE
5+ years building modern web applications end to end, ideally with Go and HTMX (plus Python), and comfortable owning distributed, asynchronous systems (queuing, background processing)
High level of hands-on AI knowledge—LLMs, RAG (such as pgvector), prompt engineering, model routing (such as OpenRouter) and frameworks like LangChain—with experience shipping AI-driven features in production
Transformative mindset toward AI-based workflows, with a focus on agentic coding: you use AI to boost your productivity while maintaining high software standards
Strong track record of end-to-end ownership: you organize delivery from scoping to launch, anticipate downstream effects and act proactively without waiting for permission
Pragmatic: you build the smallest valuable piece first, prioritize ruthlessly and leave the code better than you found it even while moving fast
True product-engineer mindset: obsessed with the user experience and the "why" behind what you build, comfortable with product metrics and driven to make a measurable impact
Excellent communicator who explains complex technical topics clearly to technical and non-technical partners and documents effectively in writing
WHY US?
An exciting product with millions of users in over 150 countries, driven by our mission to transform the world through healthy eating
A remote-first setup: work 100% from home, join a co-working space, or work abroad for several weeks per year
