Who you are

- Core responsibilities - 5+ years of experience

- You are impact-driven and thrive at the intersection of AI and ML engineering, and want to build real systems that power decision-making at scale
- A scientist and a builder: you explore multiple approaches, analyze results, and iterate fast, balancing cutting-edge techniques with simple, scalable, reliable solutions that work in production
- A strong communicator and collaborator who adapts the message to different audiences and enjoys working cross-functionally with Data Scientists, Product Managers, and Engineers, able to explain trade-offs and designs in simple terms

- Someone with a startup mindset: comfortable with ambiguity, proactive, and hands-on when something needs fixing or improving — beyond your immediate scope

- Ready to Lead Boldly – helping business leaders make decisive, high-stakes AI insights

- Applicants must already have the legal right to work in Spain or Germany

What the job involves

- Aily Labs is a B2B SaaS company building an AI-powered decision intelligence app for enterprises

- Our mobile-first platform combines company data with advanced machine learning, large language models, and agentic AI to give business leaders clear, actionable insights in real time

- Instead of traditional dashboards and reports, Aily delivers simple, personalized recommendations powered by GenAI that help teams decide and act faster across finance, supply chain, R&D;, commercial, and more
- The app is designed to be intuitive for end users and easy to integrate for IT,



so companies can move from analysis and indecision to confident, data-driven decisions every day

- Founded in 2020 in Munich, Aily Labs has grown into a general team of 300+ people across Munich, Barcelona, Madrid, Cluj, and New York

- Our mission is to democratize AI in business and enable leaders to Lead Boldly, turning complex data into decisions that drive real, measurable impact

- We are looking for AI Engineers who are passionate about the power of AI and love turning agentic systems into reliable, production-grade products: people who pair strong software engineering with applied AI, and who care as much about latency, evaluation, and robustness as they do about the model itself

- Your job is to build and scale the agentic systems that power Aily's decision intelligence platform — and to make sure they work in production, at enterprise scale

- We develop the Super Agent – an agentic decision advisor that guides users from questions to decisions through natural dialogue

- We also create vertical decision intelligence agents that synthesize insights across domains, helping F500 clients turn complex data into measurable business outcomes





- This is all pulled together with the GenAI systems that surface insights and decision triggers to ensure users can respond to risks and opportunities immediately

- We're building production LLM systems at enterprise scale – which means tackling hard problems in evaluation, reliability, and latency while staying at the research frontier

- Our challenges include grounding agents in structured business data, coordinating multi-agent workflows, and ensuring robust performance in high-stakes decision contexts

- We pair strong engineering with applied research, contributing to the field through publications and establishing technical differentiation in a fast-moving space

- Own complex features and lead technical initiatives from design to implementation — grounding agents in structured business data, multi-agent orchestration, context/memory, tool use, and fast/deep response paths, in production-grade, async, typed Python

- Take strong ownership of quality and performance: evaluation frameworks, monitoring, latency, and reliability of your team's developments in production

- Interact with other functions and agree on exchange protocols and architecture (Data Engineering, Backend, …)

- Sponsor the creation and implementation of new software and ML standards; mentor junior teammates on technical topics, including Python engineering practices (typing, async, testability)

- Communicate and align with internal and external stakeholders: present and explain the AI behind business outcomes

Benefits

- Global company and culture

- Hybrid working model

- Fast growth path
