Résumé du poste

3E is seeking a Professional Services Engineer to drive end-to-end technical delivery of onboarding onto our Asset Performance Management (APM) SaaS platform. This hands-on role sits at the intersection of software engineering, data integration, and renewable energy operations, with opportunities to lead deployments.

You’ll build data collectors, pipelines, and tooling, write Python and API scripts, and integrate diverse field data sources to model assets at scale.

Qualifications

• Solid programming ability in Python to write, debug, and maintain data movement scripts.
• Familiarity with REST APIs for consumption and integration.
• Foundational SQL skills for querying relational databases.
• A builder’s mindset, favoring automated, repeatable solutions.
• Strong communication skills to explain technical details.
• Ownership and proactive problem-solving drive.
• Bachelor’s degree in a technical field or equivalent practical experience.

Responsabilités

• Contribute to end-to-end technical delivery of asset onboarding projects, including data discovery, source-system assessment, integration, validation, and go-live.
• Build custom data collectors, transformation pipelines, and mapping tools to bridge client systems with our platform.
• Write Python and API scripts to extract, transform, and load operational data, including bulk provisioning and backfill utilities.
• Integrate with field data sources such as SCADA historians, OT/IoT platforms, SFTP feeds, and third-party APIs.
• Map and model assets at scale within the platform for various asset types.
• Support client and vendor relationships, scope work, and coordinate with client engineering teams.
• Document onboarding runbooks and repeatable processes to scale delivery.
• Collaborate with DataOps, product, and support teams to surface gaps and improve the onboarding playbook over time.

Description du poste

3E islooking for a new Professional Services Engineer to help drive the end-to-end technical delivery of large-scale asset onboarding onto our Asset Performance Management (APM) SaaS platform. This is a hands-on , build-oriented role at the intersection of software engineering, data integration, and renewable energy operations.

Over time you’ll grow into the technical lead who turns a signed contract into a live, fully integrated client deployment,standing up the integrations that feed our platform, and building the custom tooling that makes onboarding repeatable at scale.

This role suits someone who’s energized by hard integration problems, eager to take ownership and grow toward leading deployments end to end, and comfortable both talking through a problem with a client and writing the Python that solves it.

What you’ll do:

• Contribute to end-to-end technical delivery of asset onboarding projects: supporting data discovery, source-system assessment, integration, validation, and go-live for portfolios spanning many sites and large volumes of data points.

• Build custom solutions where off-the-shelf configuration falls short: data collectors, transformation pipelines, mapping tools, and automation that bridge client source systems and our platform.

• Write Python and API scripts to extract, transform, and load operational data - bulk provisioning tools, tag-mapping utilities, backfill and reconciliation scripts, and integrations against REST APIs and platform endpoints.

• Integrate with field data sources - SCADA historians, OT/IoT data platforms, SFTP feeds, and third-party APIs - learning to diagnose pipeline failures and resolve data-quality issuesalong the way.

• Map and model assets at scale, translating raw point lists and naming conventions 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, set expectations, and coordinate with client engineering teams and external integration partners.

• Document repeatable processes — onboarding checklists, integration runbooks, and how-to guides - so that delivery scales beyond any single engineer.

• Partner with internalDataOps, product, and support teams to surface platform gaps, feed real-world field learnings back into the product, and improve the onboarding playbook over time.

Requirements

What we are looking for:

• Solid programming ability in Python — you can write, debug, andmaintainscripts that move and transform data, andyou’recomfortable picking up a messy point list and a loose spec and producing working code.

• Familiarity with APIs — a working understanding of how to consume and build against REST APIs (authentication, requests/responses, handling errors), with eagerness to deepen this in production.

• Foundational SQL skills — comfortable querying relational databases to extract andvalidatedata.

• A genuine builder’s instinct — you reach for an automated, repeatable solution rather than a manual one, andyou’reexcited to create tooling thatdoesn’texist yet.

• Strong communicationskills — able to explain technicaldetailsclearly and work well with both teammates and clients.

• Ownership and problem-solving drive — you stay with a hard problem, ask good questions, and push to resolution.

• A bachelor’s degree in a technical field (computer science, engineering, data, or similar)orequivalent practical experience.

Nice to have:

• Exposure to the solar, renewable energy, or broader power/utilities sector — a small amount of domain experience is a real plus, but the right engineer canlearnthe domain.
• Familiarity with SCADA / historian systems (e.g., Ignition, OSIsoft/AVEVA PI, or similar) and industrial/OT data.
• Understandingofutility-scale solar or BESS operations — inverters, trackers, meters, met stations, and the data they produce.
• Experience with time-series data at scale, including aggregation, interpolation, and backfill considerations.
• Familiarity with APM, EAM, or asset monitoring platforms, or related performance/availability reporting concepts.
• Exposure to energy-market or grid data feeds and the access mechanics that come with them.
• Experience with version control, scripting for automation, and lightweight ETL.

Benefits

In addition to joining a fast-growing international company that promotes a stimulating atmosphere in a highly motivated group of people, 3E offers a unique opportunity to further develop yourself in a company with an ambitious growth plan, delivering innovative services.

In this role, you’llwork on real assets producing real power, with the autonomy to design the technical solution and the visibility of owning the outcome. Every onboarding is a fresh integration puzzle, and the tooling you build compounds — making the next deployment faster and the platform stronger.If you want to be the technical engine behind how clients actually get live, this is that seat.
