[Hiring] Senior Sustainment Engineer @Mytra

Role Description

As a Senior Sustainment Engineer at Mytra, you will join our Customer Operations team as we scale from early customer deployments to a growing installed base of live, production sites. Once a site moves through commissioning and into hypercare, Sustainment is the team that keeps it running and you’ll be the hands-on engineering leader closing the loop between what’s happening on the floor and what Engineering needs to know.

The Senior Sustainment Engineer owns technical escalation for complex field issues once a site moves from deployment into hypercare and steady-state operations. You’ll be the engineer other Sustainment Engineers and field technicians escalate to when a fix isn’t obvious, and the person customers trust to close the loop on uptime and reliability commitments.

This role includes periodic rotating on-call or after-hours escalation coverage to support customer uptime commitments outside standard site hours.

This role is designed for someone who can operate independently on ambiguous, high-stakes field problems, build structure where none exists yet, and grow into ownership of reliability and sustainment strategy across multiple customer sites.

What You'll Do

• Own technical escalation for complex field issues, leading root cause analysis (RCA) and corrective/preventive action (CAPA) on recurring or high-impact failures.
• Translate field performance data and RCA findings into engineering feedback & change requests (ECRs) and design-for-reliability / design-for-supportability recommendations, in partnership with Engineering & Manufacturing.
• Track and report on sustainment readiness metrics (MTBF, MTTR, uptime, service responsiveness) across your assigned site(s), and flag emerging reliability trends before they become systemic.
• Own the technical handoff from Deployment into hypercare, validating that closeout artifacts, installed-base records, and open-issue trackers are complete and accurate before a site transitions to steady-state support.
• Build and maintain technical support guides, troubleshooting manuals, and standardized playbooks that reduce reliance on tribal knowledge and speed up issue resolution across the field team.
• Direct spare parts planning, service kit deployment, and CMMS/PLM usage for your site(s), and supervise external contractors where used.
• Mentor Sustainment Engineers and field technicians in troubleshooting discipline, documentation quality, and safe field practices.
• Escalate issues with clear context — root cause hypothesis, objective evidence, affected systems, and recommended next actions — and drive them to resolution with Engineering, Product, and the customer.

Qualifications

• 4+ years of progressive experience in field service, reliability engineering, customer support engineering, or sustainment/maintenance engineering roles, ideally with robotics, industrial automation, or complex electromechanical systems.
• Hands-on electromechanical troubleshooting experience: wiring, connectors, sensors, actuators, and diagnosing issues around partially energized systems using hand and power tools.
• Demonstrated RCA/CAPA experience and comfort owning a technical issue from first report through documented resolution.
• Working knowledge of reliability and sustainment metrics (MTBF, MTTR, uptime) and how they’re used to gauge system performance.
• Familiarity with CMMS/PLM systems for tracking parts inventory and maintenance work orders (Netsuite preferred).
• Clear cross-functional communication: comfortable escalating to engineering leadership, briefing customers directly, and mentoring less-experienced engineers.
• Demonstrated safety discipline in live, powered industrial environments.
• Ability to read electrical schematics and mechanical drawings.

Requirements

• Bachelor’s degree in Mechanical, Electrical, Manufacturing, or Systems Engineering, or equivalent hands-on experience (nice to have).
• Experience supervising external contractors or vendor service technicians (nice to have).
• Experience supporting new product introduction (NPI), defining field readiness or lifecycle support requirements (nice to have).
• Spanish/English bilingual communication skills (nice to have).
• Experience building or improving technical documentation, training materials, or standard operating procedures from scratch (nice to have).
• Able to perform physical labor for the duration of a shift, including standing for extended periods, climbing ladders, crouching, and crawling into tight spaces.
• Able to lift and carry up to 40 pounds from the floor.
• Able to work at heights with appropriate fall protection.

Benefits

• Competitive compensation and equity grants at a high-growth company backed by top-tier VCs.
• Fully subsidized health coverage, including medical (baseline plans), dental, and vision for employees and dependents.
• 401(k) plans and employer-subsidized life insurance.
• Fully subsidized lunch and snacks at HQ—we eat and share stories together at the “long” table.
• Generous PTO and company-paid holidays, including one week over the winter break so everyone can recharge together.
• Voluntary pet insurance, Voluntary Life Insurance, Accident, Critical Illness, and Hospital Indemnity.
• Fully subsidized tax advisory services and education to help you understand your equity.
• Commuter benefits, including a up to $150 monthly commuter benefit.
• Lively, modern combined office and lab space where we rapidly iterate through design, build, and test phases.
• Fully equipped onsite gym and showers at headquarters.
