About the Job

Requirements

  • At least 8 years of experience in service systems, reliability, fleet or asset monitoring, NOC, or field data engineering, including hands-on monitoring of assets deployed in the field.
  • A Bachelor of Science degree in Computer Science, Data Science, Electrical Engineering, or a related field, or equivalent practical experience.
  • Deep understanding of telemetry, fleet monitoring, and incident response; experience building ticketing, FRACAS, genealogy or traceability, or over-the-air update systems.
  • Experience leading or mentoring a small team and setting technical and process standards.
  • Strong programming skills in Python, SQL, and data modelling.
  • Experience with telemetry and time-series data stacks such as InfluxDB, TimescaleDB, and Grafana on AWS or Azure.
  • Experience defining requirements for or building internal ticketing and field service tools.
  • Experience with PLM/ERP systems such as Arena and NetSuite for genealogy, bill of materials, and RMA traceability.
  • Experience designing and building staged over-the-air firmware rollout pipelines; familiarity with tools such as Mender or AWS IoT is a plus.
  • Advanced Jira skills, including workflow design and integrations.
  • Knowledge of alerting, observability, incident management practices, APIs, and system integration.
  • Willingness to travel 10–25%, including occasional multi-week deployments, and work extended hours when fleet or customer issues demand.
  • Ability to work with software, electrical, and hardware engineers and communicate clearly with customers.

Responsibilities

  • Design and implement one service record per unit, linking tickets, site visits, RMAs, configuration, and firmware history across the fleet.
  • Partner with the software team to design and build an in-house ticketing and field service platform, defining requirements, data models, and workflows, and integrating it with PLM/ERP, telemetry, and engineering systems.
  • Establish as-built and as-maintained genealogy for every unit, down to serialized assemblies, so each unit’s full history is traceable in minutes.
  • Build and run the FRACAS process and tooling that links field failures to Engineering, drives root-cause analysis and corrective action, and reduces warranty cost and repeat failures.
  • Partner with firmware and software teams to design and operate staged, safe over-the-air rollouts with fleet cohorts, health gates, monitoring, and rollback.
  • Design NOC processes, alerting, dashboards, on-call and escalation paths that scale with the fleet, and hire and lead a small team to run them.
  • Use telemetry and field data to investigate and diagnose complex unit and fleet issues, respond to customer-impacting events, and turn findings into fixes.
  • Contribute as needed in the startup environment, including site support, data analysis, reporting, and process design.

Desired Qualifications

  • Experience in energy, power electronics, data centres, industrial IoT, EV/charging, or other connected hardware fleets.
  • Experience at a startup or early-stage hardware company.
  • Reliability engineering background, including FMEA, Weibull analysis, or MTBF.
  • Experience setting up a NOC or 24/7 monitoring operation from scratch.
  • Familiarity with industrial protocols such as Modbus, DNP3, and IEC 61850, and SCADA/BMS integration.
  • Knowledge of power electronics or medium-voltage equipment.
  • Cloud or ITIL certifications.

About the Company

Amperesand

Modular solid-state transformers for grid power

Amperesand develops modular solid-state transformers (SSTs) for grid infrastructure using silicon carbide (SiC) devices and proprietary high-frequency transformers. The SSTs are digitally controlled and bidirectional, offered in 2, 4, and 6 MW modules that can be combined to meet larger needs, replacing traditional transformers, switchgear, and UPS in a single AI-driven system. It differentiates itself through the combination of SiC SSTs, proprietary high-frequency transformers, digital power management, and leadership from NTU R&D spun out with Temasek’s Xora Innovation, plus an experienced team from ABB, GE, Siemens, and Vestas. The goal is to speed up the energy transition by delivering scalable, compact SST systems for EV charging networks, microgrids, data centers, and industrial power, with first deliveries planned for 2025 in the US and Singapore.
