What are the key skills and qualifications needed to thrive as a Second Engineer, and why are they important?

To thrive as a Second Engineer, you need strong knowledge of marine engineering principles, machinery operation, and maintenance, typically supported by a relevant engineering degree and a Certificate of Competency (STCW). Familiarity with engine room management systems, diagnostic tools, and compliance with international maritime regulations is essential. Strong problem-solving abilities, teamwork, and effective communication distinguish top performers in this role. These skills and qualifications are crucial for ensuring the safe, efficient operation of a vessel's machinery and compliance with safety and environmental standards.

What are Second Engineers?

A Second Engineer, also known as the First Assistant Engineer, is a licensed member of the engineering department on a ship. They are responsible for overseeing the day-to-day operations and maintenance of the vessel's engine room and its machinery. The Second Engineer ensures that all systems are running efficiently, supervises engine room staff, and assists the Chief Engineer with technical operations and record-keeping. Their role is essential for the safe and smooth functioning of a ship's propulsion and auxiliary systems.

What is the difference between Second Engineer vs Third Engineer?

AspectSecond EngineerThird Engineer
CertificationsSTCW certifications, Marine Engineering LicenseSTCW certifications, Marine Engineering License
Work EnvironmentOnboard ships, engine roomOnboard ships, engine room
ResponsibilitiesAssist Chief Engineer, maintain engine systems, supervise junior engineersAssist Second Engineer, perform routine maintenance, support engine operations
Industry UsageMaritime shipping, cruise linesMaritime shipping, cruise lines

The Second Engineer and Third Engineer roles are both vital engine department positions on ships, requiring similar certifications and working in the engine room environment. The Second Engineer typically has more responsibilities, including supervising junior staff and overseeing engine maintenance, while the Third Engineer supports these tasks and handles routine maintenance. Both roles are essential for safe and efficient ship operations within the maritime industry.

What are the main responsibilities of a Second Engineer on a commercial vessel, and how do they interact with other crew members?

As a Second Engineer, you are primarily responsible for overseeing the day-to-day operations and maintenance of the vessel's engine room and machinery. This involves supervising engine room staff, conducting regular inspections, troubleshooting technical issues, and ensuring compliance with safety and environmental standards. You will work closely with the Chief Engineer to implement maintenance schedules and may also coordinate with deck officers and other departments to ensure smooth vessel operations. Effective communication and teamwork are essential, as you will routinely delegate tasks and report maintenance activities to both senior officers and your team.

Job description

The Role

As a Senior MLOps Engineer, you will own the infrastructure and ML platform that powers ClimateAi's forecasting and risk products. You will design, build, and operate the cloud systems, data management infrastructure, and model lifecycle tooling that allow our Data Science and ML Engineering teams to develop, compare, register, and ship models with confidence.

This is a high-leverage role at the intersection of infrastructure, ML platform, and security. You will partner closely with Data Science to unblock initiatives like SYO2 and Risk Outlooks model improvements by giving them a real model management platform; with Data Engineering to harden our data lakehouse and pipelines; and with our security lead to provide a strong second engineer on cloud security - building skill duplication across critical systems.

Our hybrid work schedule includes 3 in-person days at one of our core locations (SF,  Boston) and 2 remote days.

What You'll Do
  • Stand up and operate the ML model framework that provides ML engineers and data scientists experiment tracking, model registry, and lineage
  • Own and evolve our Infrastructure as Code so environments are reproducible, auditable, and easy for engineers to extend
  • Build CI/CD and deployment patterns for ML pipelines and models, including reproducible training, automated validation, and safe rollouts to production
  • Improve data management systems alongside Data Engineering with storage tiering, lifecycle and retention, cost-performance tradeoffs, and observability across our cloud environments
  • Author clear architectural documentation, runbooks, and design proposals to communicate tradeoffs to engineering and non-technical stakeholders
What We're Looking For
  • 3-5 years of experience in Machine Learning, Backend Software Engineering, Data Engineering, or MLOps roles supporting data-intensive systems in production
  • Production experience with ML lifecycle management platforms such as MLFlow, Weights & Biases, Neptune.ai, Comet.ml or similar
  • Experience with IaC using Terraform, Pulumi, OpenTofu, Encore, Crossplane or similar
  • Deep experience with building systems-of-systems in AWS, GCP, or Azure, that span across multiple services or multiple cloud providers
  • Strong communication and ownership. You scope your work, monitor what you ship, and drive problems to permanent resolution
  • Ability to collaborate closely with Data Scientists, Engineers, and Product, to design and support end-to-end ML workflows.
Bonus Points
  • Experience with training, inference, deploying, and scaling modern ML models to production
  • Experience with configuring models with datasets up to the petabyte-scale
Leveling

This role is posted at our Senior Engineer (P3) level. You will be a self-directed engineer who independently designs, implements, and optimizes complex infrastructure and ML platform components, drives data and model quality, supports cross-functional teams, and provides technical mentorship within the team. Leveling decisions are made in partnership with candidates through the interview process.

Compensation

The base compensation range for employees based in the US is $170,000-200,000 and equity in line with experience and company stage. This salary range may be inclusive of several career levels at ClimateAi and will be narrowed during the interview process based on a number of factors, including the candidate's experience, qualifications, business need and US location.

ClimateAi is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
