What makes RightShip a great place to work at:

RightShip is an equal opportunity employer, and we champion diversity. Our teams are composed of individuals from different geographies, cultures, religions, ethnicities, races, genders, sexual orientations, abilities, and generations. We believe that a diversity of experiences makes us stronger—as individuals, as communities and as an organization.

Don’t meet every single requirement of this role? Still apply! Research tells us that that women and underrepresented groups are less likely to apply unless they meet every single requirement.  At RightShip we believe that the right hire is someone who makes an addition to our culture, rather than someone who fits in and conforms to our status quo. We want to add team members who not only value RightShip standards and workplace culture, but also bring an aspect of diversity that positively contributes to our work environment. If you are excited about this role, or about our company in general, we would love to hear from you!

RightShip is scaling its use of AI from traditional ML models to advanced LLM-based reasoning systems, to support safer and more sustainable maritime operations. We are looking for a Data Scientist who can bridge both worlds: classical data science and modern AI/LLM governance.

This role is responsible for defining how models should be evaluated, monitored and governed across their lifecycle. You will work closely with domain experts, the existing AI team, data engineering and product teams to ensure our AI systems behave consistently, accurately and responsibly.

This is not an LLM-engineering or roadmap ownership role. It is a senior position focused on methodological leadership, model quality, and governance across AI and ML systems.

Major Responsibilities 

• Establish Best Practices for AI/LLM & Traditional ML Experimentation:
• Develop experimental methodologies for both classical ML and LLM-based systems.
• Standardise how experiments are structured, documented and compared across teams.
• Create reproducible workflows for testing prompts, model versions, embeddings and classical feature models.
• Ensure statistical soundness and methodological rigour in all experiments.
• You define “what goods like” in experimentation.
• Own the Evaluation Framework for Model Behaviour:
  • Build and maintain evaluation datasets, test suites and metrics for:
    • reasoning accuracy (LLMs)
    • classification performance (traditional models)
    • consistency and drift
    • hallucination checks
    • edge-case handling
    • domain-alignment
• Continuously refine the evaluation approach as the AI team iterates on models.
• Translate Domain Logic into Structured Model-Ready Logic
  • Work with maritime SMEs to understand inspection logic, safety reasoning and operational decisoin pathways.
  • Convert that knowledge into:
    • Classification schemas
    • Decision flows
    • Label definitions
    • Reasoning templates
    • Structured input/output rules for LLMs and ML models
• Ensure model behavior is grounded in real-work operational judgement.
• Support AI Team Experimentation . You will :
  • Provide guidelines, quality criteria and methodology for the AI team’s test design.
  • Review final experiments and highlight gaps, inconsistencies or risks.
  • Ensure that experimentation aligns with the governance, evaluation and lifecycle frameworks you maintain.
  • Maintain the benchmark suite the AI team must compare against.
• Conduct Traditional Data Science & ML Work
  • You will also contribute hands-on to classical data science tasks such as:
  • Analysis of structured datasets.
  • Feature engineering and exploratory data analysis.
  • Building classification or scoring models as needed (supervised ML).
  • Supporting domain teams with insights, prototypes or predictive modelling.
  • Working with data engineers to refine the data required for ML.
• Model Monitoring & Lifecycle Governance
  • Build processes for ongoing monitoring of AI behaviour and model drift.
  • Investigate anomalies or unexpected outputs.
  • Identify failures rooted in data, logic, edge cases or prompt structure.
  • Recommend corrective actions (model retraining, logic updates, new test suites, prompt refinement).
  • Maintain transparent documentation, audit trails and governance standards aligned with RightShip’s risk posture.

Qualifications, Skills & Experience  

• Bachelor’s or Masters (preferred) degree in Data Science, or relevant field.
• 7+ years in Data Science, Applied ML or AI-focused role
• Postgraduate studies or AI governance training is advantageous.
• Curious, a critical thinker and a strong sense of logic
• Superior mathematical ability
• Strong experience building and evaluating classification and supervised ML models.
• Excellent communication and presentation skills
• Excellent at establishing standards others can follow confidently.
• Proficiency in Python, SQL and model evaluation frameworks.
• Familiarity with MLflow (or equivalent), Vector DBs or LLM orchestration tools is a plus.
• Ability to influence through expertise rather than authority.
