Senior AI Engineer

Are you curious about AI and ready to bridge the gap between high-level strategy and production-ready code? Do you want to use your (Gen)AI knowledge and ML engineering skills to help fast-growing Climate Tech scale-ups build solutions that genuinely matter? At Enjins, you'll have the freedom to work with the latest technologies while creating real, lasting business value - all within a growth-oriented team that values collaboration, celebrates together, and includes everyone.

Since 2018, we've been engineering AI systems designed to deliver long-term, meaningful value. Operating from Utrecht and Berlin, we partner with innovative tech companies across Northwest Europe - including Groendus, SnappCar, Next Sense, Crisp and Beyond Weather - and actively prioritise partnerships in Climate Tech where our technology delivers measurable positive impact.

We build data & AI solutions. At Enjins, we operate with a product mindset, meaning we take full ownership of the technical lifecycle - from initial discovery to a scaling, production-grade engine that lives within our partners' infrastructure. At our core, we are engineers first: clean code, MLOps best practices, and system reliability. Our team is a growth-oriented group of engineers from diverse cultural, academic, and professional backgrounds.

As a Senior AI Engineer, you will work at the intersection of technical excellence and project leadership within our team of 20+ engineers. You will act as a hands-on technical lead in a consultancy context, ensuring the impact of AI applications for innovative Dutch and international clients.

Key responsibilities:

• Own the full development and implementation of robust AI/ML applications, ensuring systems are scalable and production-ready.
• Support the growth of our engineering team by sharing knowledge on technologies like Kubernetes, Airflow, and Kafka — and by mentoring more junior engineers.
• Act as a technical partner for stakeholders, translating complex AI architectures into clear business value and human-centric impact.
• Play an active role in building Enjins: participating in interviews and identifying new tools and methods that increase team velocity.

A concrete example: within your first months you might lead the deployment of a renewable-energy forecasting model for a Climate Tech client - end-to-end, from data pipeline to production API with full MLOps coverage. That's the kind of work we do.

Within 1 Month

• Complete Enjins onboarding and become a certified cloud practitioner (AWS, Azure, or GCP).
• Start your first client project, working alongside an experienced Enjins engineer who acts as your buddy.
• Meet your dedicated Coach and Buddy who support your first two months.

Within 3 Months

• Take ownership of a client's AI/ML application from architecture through deployment.
• Begin mentoring junior engineers and actively sharing knowledge within the team.

Within 6 Months

• Drive measurable velocity improvements for your client.
• Contribute to team growth - identifying tooling improvements and participating in the hiring process.

We're looking for pragmatic engineers who thrive on solving complex problems with clean, scalable code - whether your background is software engineering, data science, econometrics, or another quantitative field. If you're willing to expand your skills and grow, we want to hear from you.
