DESCRIPTION
Key job responsibilities
- Own the end-to-end vulnerability mitigation strategy for third-party software across Amazon, setting goals and metrics that drive measurable reductions in risk exposure.
- Design and build auto-remediation capabilities that resolve vulnerabilities at machine speed, leveraging vulnerability scanning data and defense-in-depth principles to deploy updates safely across the fleet without manual intervention.
- Manage and grow an inclusive team of 11 software development engineers and security engineers through collaborative development planning, coaching, and strategic project assignments tied to individual career goals.
- Partner with AWS service teams and Amazon Security peers to analyze unpublished vulnerabilities in open source software, build threat models, and implement guardrails that prevent vulnerable packages from entering the fleet.
- Apply generative AI tooling to accelerate vulnerability analysis and remediation workflows, and establish data-driven reporting that keeps leadership informed on progress and outcomes.
A day in the life
You will start your morning reviewing vulnerability scanning data and triaging emerging third-party software risks with your security engineers and software development engineers. From there, you may join a working session with an AWS service team to align on a remediation rollout for an open source dependency, then move into a design review where your team is iterating on a new auto-remediation capability. You will spend time in one-on-ones with your direct reports discussing their growth, and close out the day drafting a narrative that communicates your team's progress and strategy to senior leadership.

- Insurance
What Employers Look For
The qualifications that appear most often in third engineer jobs.
- Valid STCW basic safety training certification (BST) required
- Third Engineer USCG or flag-state license for appropriate vessel tonnage
- Minimum documented sea service hours on comparable vessel types
- Proficiency in engine room watchkeeping, maintenance, and log-keeping
- Experience with diesel propulsion, auxiliary generators, and fuel systems
- Ability to pass a pre-employment drug screen and physical examination
Tips for Your Third Engineer Job Search
Tailor your STCW certifications section first
Hiring managers in maritime roles scan for specific STCW endorsements before reading anything else. List each certificate with its issue date and issuing authority so a recruiter can verify eligibility at a glance without digging through attachments.
Quantify your engine room watch hours
Third engineer roles require documented sea service hours. Convert your discharge book entries into a clear summary on your resume, grouping hours by vessel type and propulsion system so companies can confirm you meet their minimum sea service thresholds quickly.
Apply early to roles that fit
Migrate Mate lists third engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Filter openings by vessel class and trade route
Third engineer responsibilities differ significantly between deep-sea container ships, offshore supply vessels, and inland towing fleets. Target listings that match the vessel types and propulsion systems you have documented hours on, since employers rarely train across vessel classes at this rank.
Prepare for a practical interview, not just verbal
Many maritime employers include a technical walkthrough or scenario-based assessment covering lube oil systems, bilge operations, or emergency shutdowns. Refresh your working knowledge of the specific machinery types listed in the job posting before you interview.
Negotiate your rotational schedule before you sign
Vessel contracts vary widely in rotation length, from four weeks on to months-long deployments. Confirm the rotation cycle, relief policy, and travel reimbursement terms during the offer stage, since these affect your effective compensation and time ashore significantly.
Third Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most third engineers?
Amazon, Optum, and Commonwealth Fusion Systems are hiring the most third engineers right now, with openings concentrated in Texas, Massachusetts, and Virginia, based on current listings on Migrate Mate as of November 2026. Activity tends to cluster around port-heavy states and offshore energy regions.
How many third engineer jobs are remote?
About 0% of third engineer openings are fully remote or hybrid as of November 2026, reflecting the hands-on, vessel-based nature of most positions. The sub-areas with the most flexible arrangements include technical support, training, and shore-side fleet engineering roles rather than active watchkeeping assignments.
How do you become a third engineer?
Becoming a third engineer starts with completing an accredited maritime academy program or accumulating qualifying sea service hours as an unlicensed engine department rating. You then apply to the U.S. Coast Guard for a third engineer license, submitting proof of sea service, completed STCW endorsements, and passing a written examination covering thermodynamics, machinery systems, and regulations.
How do you get hired as a third engineer with little experience?
Start by targeting companies that operate training vessels, domestic ferries, or inland fleets, since these employers are more likely to hire candidates with limited offshore experience. Highlight any engine room time logged during academy training, internships, or entry-level ratings work. Getting your STCW endorsements current and your USCG application submitted before you apply signals readiness even when your sea service hours are at the minimum threshold.
What does the third engineer interview process look like?
Most third engineer interviews begin with a document review covering your license, STCW certificates, and sea service record. A technical interview follows, typically asking you to walk through watch routines, describe how you would respond to an engine room alarm, and explain your familiarity with the vessel class. Some operators add a practical assessment or simulator session before extending an offer.
Where can I find and apply to third engineer jobs?
You can find and apply to third engineer jobs on Migrate Mate, which lists current openings from employers across the United States. Search the listings to find roles that match your license level, vessel experience, and rotation preferences, then apply directly to each one that fits.
