Transmission Planning Software Engineer - Pitch Aeronautics

Shape how WireWeather integrates with power flow. You will sit at the intersection of transmission planning practice and software development: defining the methodologies we implement, writing the code that implements them, and engaging directly with RTO/ISO and utility planners to make sure what we ship actually fits how they do their jobs.

Description

This is a hands-on engineering role. You will own the planning side of the product, and provide expertise on what studies we can run, what assumptions are defensible, what reports we produce, and how our outputs hold up to scrutiny from a senior planner or interconnection engineer.

We expect the strongest candidates to be deep on transmission planning first and to either write code already or be eager to grow that skill alongside a strong software team. We are also interested in strong engineers from the software side with real interconnection-study exposure.

Why we need your help

Pitch Aero builds WireWeather, a Dynamic Line Rating (DLR) forecast product for the bulk electric system. We turn high-resolution weather forecasts into hourly ratings for transmission lines, and we are increasingly embedding those ratings inside the power flow workflows that planners and operators use to make decisions like interconnection studies, N-1 contingency analysis, and capacity assessments.

Our software stack today includes a Sienna power flow service, Python analysis pipelines, and a Flutter web dashboard for planners.

Responsibilities

• Decide how line ratings are applied in DC and AC power flow studies, contingency analysis (N-1, and N-1-1 / N-2 where applicable) , PTDF/LODF sensitivity work, and generator interconnection (GI) capacity calculations.
• Contribute Python analysis scripts and Sienna power flow service code. Build new study types, improve solver and contingency handling, and integrate our forecast data into the planning workflow.
• Lead non-curtailment interconnection studies and similar engagements end to end: case ingestion (PSS/E .raw/.rawx, PSLF .epc), base-case validation, contingency screening, rating application, and report production.
• Engage RTO/ISO transmission planners, utility planning engineers, and IPPs to understand what they need, what's defensible in their process, and what would actually move the needle on their interconnection queues and reliability assessments.
• Bring your planning experience to product decisions. Guide our team with an understanding of what features matter, what reports they expect, what edge cases will break trust the first time a planner pressure-tests our output.
• Review study results and reports from other engineers for physical plausibility, methodology soundness, and presentation quality.
