Senior Machine Learning Engineer

We're Hiring: Senior Machine Learning Engineer Portugal

We're partnering with a fast-growing global game-tech company to find a Senior ML Engineer who's ready to lead - not just build.

This is a role for engineers who think in systems, mentor those around them, and take real ownership of complex AI products from concept to production.

What you'll be working on:

Designing and delivering end-to-end ML pipelines at scale in distributed environments

Building real-time inference systems and model serving solutions

Owning MLOps: CI/CD, drift monitoring, automated evaluation, and alerting

Leading project planning, roadmaps, and post-launch retrospectives

Collaborating cross-functionally with Data Scientists, Data Engineers, and Product Owners

What makes this role stand out:

This isn't a heads-down engineering seat. You'll mentor fellow engineers, drive technical vision, and help shape how ML is operationalised across an AI department spanning fraud detection, personalised recommendations, CRM optimisation, and AI-powered copilots.

What you bring:

Deep Python experience in large-scale, high-performance production environments

Proven ability to design complex, scalable ML systems - and influence broader technical outcomes

Hands-on with Azure or AWS, and tools like Kubernetes & Docker

Experience with real-time data streaming (Kafka, Spark Streaming)

Strong MLOps knowledge: MLflow, Kubeflow, and the full ML project lifecycle

A genuine track record of mentoring and growing engineers

Excellent communication skills - you can make complex technical ideas land with any audience

Location: Portugal (fully remote or hybrid with 1 day/week in the office if you're based in Lisbon)

Employment: Direct hire with our client

Benefits:

• Performance bonus of up to 22%
• Company card with a monthly personal spending allowance
• Private healthcare coverage
• Meal card & WFH allowance
• Unlimited Udemy access
