Professional Services Engineer

About the role

3E is looking for a Professional Services Engineer to drive the end-to-end technical delivery of large-scale asset onboarding onto its Asset Performance Management (APM) SaaS platform. It is a hands-on, build-oriented role combining software engineering, data integration and renewable energy operations, with a hybrid workplace. Over time the engineer grows into the technical lead who turns a signed contract into a live, fully integrated client deployment.

Key responsibilities

• Contribute to end-to-end technical delivery of asset onboarding projects, covering data discovery, source-system assessment, integration, validation and go-live for portfolios across many sites.
• Build custom solutions such as data collectors, transformation pipelines, mapping tools and automation that bridge client source systems and the platform.
• Write Python and API scripts to extract, transform and load operational data, including bulk provisioning, tag-mapping, backfill and reconciliation scripts.
• Integrate with field data sources such as SCADA historians, OT/IoT platforms, SFTP feeds and third-party APIs, diagnosing pipeline failures and data-quality issues.
• Map and model assets at scale, turning raw point lists into the platform's data model for inverters, trackers, meters, weather stations, transformers and storage systems.
• Support the technical relationship with clients and vendors, helping scope work and coordinate with client engineering teams and integration partners.
• Document repeatable processes such as onboarding checklists, integration runbooks and how-to guides.
• Partner with DataOps, product and support teams to surface platform gaps and feed field learnings back into the product.

Required profile

• Bachelor's degree in a technical field (computer science, engineering, data or similar) or equivalent practical experience.
• Solid programming ability in Python, debugging and maintaining scripts that move and transform data.
• Familiarity with REST APIs, foundational SQL skills, and a builder's instinct for automated, repeatable solutions.
• Strong communication skills and ownership and problem-solving drive.
• Nice to have: exposure to solar, renewable energy or power/utilities, SCADA/historian systems, utility-scale solar or BESS operations, time-series data, APM/EAM platforms, and version control and ETL.

What we offer

• A base salary in line with experience.
• Unlimited PTO.
• Health plan (United Healthcare) for employee and family, with optional dental and vision insurance (50% employer coverage).
• Life insurance.
• 401(k) with employer matching up to 4% of salary, then 50% more between 4% and 6%.
