Hands-on Senior Data Engineer to design and maintain scalable AWS ETL/ELT pipelines, evolve a data lakehouse with Apache Iceberg, implement governance and security, optimize performance and costs, enable analytics-ready datasets, and ensure reliability, monitoring, and data quality.

Manage supplier quality for BESS and related equipment across procurement, factory testing, and field installation. Conduct supplier selection, audits, FAT witness, review ITPs, track non-conformances, and drive corrective actions to ensure compliant, traceable quality deliverables.

The Controls Engineer deploys and configures control systems for Battery Energy Storage projects, supports commissioning, troubleshoots PLC logic, and collaborates with various engineering teams.

Lead assessment, documentation, testing, and improvement of internal controls (financial, operational, ITGC). Perform process walkthroughs, control testing, IT scoping, remediation tracking, and auditor coordination. Support GRC tooling, mentor junior staff, and drive continuous improvement to ensure ICFR readiness across locations and systems.

As a Jr. AWS Cloud Engineer, you will manage AWS infrastructure, optimize networking, collaborate with DevOps, and support troubleshooting independently.

Lead design, validation, and optimization of utility-scale BESS projects. Perform battery sizing and lifecycle modeling, vendor model review, inverter/PCS modeling, and controls strategy validation. Drive EMS, Plant Controller, and SCADA integration, and deliver operational analytics using Python and engineering toolchains.

Own and harden the RHEL-based OS and container platform for on-prem energy SCADA hosts. Build/version RHEL and SCADA container images, run containers via Podman/quadlets, manage host networking and firewall, define patch/lifecycle strategies for offline sites, troubleshoot OS/container/runtime issues, and document runbooks. Maintain Windows image pipeline in steady state.

Provide legal support for energy storage, power infrastructure, and data center energy solutions by drafting, reviewing, and negotiating a high volume of complex commercial agreements; support project execution with amendments, claims, and milestone tracking; manage contract lifecycle systems, develop templates and risk frameworks; and advise cross-functional teams on contract interpretation and dispute resolution.

Field-facing role to deploy, configure, and support OT networks for utility-scale BESS projects. Ensure reliable communications between EMS, PCS, BMS, protection relays, meters, and SCADA; troubleshoot, document architectures, support FAT/SAT, and hand over sites to service teams.

Execute and witness Factory Acceptance Tests (FATs) and inspections for BESS equipment, manage supplier quality, document and track non-conformances, support RCA and corrective actions, perform field inspections during construction and commissioning, verify compliance with drawings and ITPs, and maintain quality records and reporting aligned with ISO 9001.

Develop, implement, and improve manufacturing processes to meet safety, quality, delivery, and cost targets. Troubleshoot production issues, validate supply chain readiness, support new product introduction and ramp-up, partner with design and supply chain, monitor KPIs and drive continuous improvement across manufacturing operations.

Support the full data workflow: ingest and structure data, perform cleaning and validation, run exploratory analysis and visualizations, assist with ML/DL experiments and model evaluation, and contribute to predictive maintenance and ERCOT market analytics projects.

Design, build, and maintain automated UI test suites using Playwright/Selenium and Python; perform API testing; integrate tests into CI/CD; log and track defects; debug flaky tests; collaborate with developers and product owners; maintain test documentation and participate in Agile ceremonies.

Design, simulate, and implement advanced control strategies and mathematical models for nonlinear power-electronic systems (inverters, microgrids, BESS). Apply system identification, prototype and perform real-time lab testing (MIL/SIL/PHIL/CHIL), rapid-control-prototyping, and collaborate with multidisciplinary teams to validate controllers and optimization techniques, including ML-based methods.
