Job description

At BairesDev®, we've been leading the way in technology projects for over 15 years. We deliver cutting-edge solutions to giants like Google and the most innovative startups in Silicon Valley.

Our diverse 4,000+ team, composed of the world's Top 1% of tech talent, works remotely on roles that drive significant impact worldwide.

When you apply for this position, you're taking the first step in a process that goes beyond the ordinary. We aim to align your passions and skills with our vacancies, setting you on a path to exceptional career development and success.

Data Science Technical Lead (Python + Ontology) at BairesDev

In this role, you'll lead the design and delivery of a semantic data platform, from the domain ontology to the Python pipelines and machine learning components built on top of it. You'll guide technical decisions with pragmatic modeling judgment and set the engineering standard for the team. It's your opportunity to shape how reference data becomes a trusted, well-modeled knowledge foundation.

What You'll Do

• Lead the technical direction of data science and machine learning work.
• Design a bounded domain ontology from a reference dataset.
• Build production Python pipelines for semantic processing and entity resolution.
• Integrate ontology services into the pipeline.
• Develop evaluation harnesses and solver adapters.
• Mentor engineers and set engineering standards across the team.

What We Are Looking For

• 6+ years of experience in data science and machine learning engineering, including technical leadership.
• Engineering-grade Python skills, producing production pipeline code for semantic pipelines, entity resolution, service integrations, evaluation harnesses, and solver adapters, beyond notebook analysis.
• Expertise in ontology and semantic data modeling with RDF 1.1, OWL 2, and SHACL.
• Background designing a bounded domain ontology from a reference dataset, including entity types, typed relationships, cardinality and shape rules, controlled vocabulary, and immutable versioned snapshots.
• Pragmatic modeling judgment, favoring OWL RL or EL where they suffice over unnecessary OWL DL expressiveness.
• Advanced proficiency in English.

How we do make your work (and your life) easier

• 100% remote work (from anywhere).
• Excellent compensation in USD or your local currency if preferred
• Hardware and software setup for you to work from home.
• Flexible hours: create your own schedule.
• Paid parental leaves, vacations, and national holidays.
• Innovative and multicultural work environment: collaborate and learn from the global Top 1% of talent.
• Supportive environment with mentorship, promotions, skill development, and diverse growth opportunities.

Join a global team where your unique talents can truly thrive and make a significant impact!
