Transmission Planning Software Engineer

Pitch Aeronautics is a rapidly growing startup creating innovative solutions for the utility industry. The Transmission Planning Software Engineer will integrate transmission planning practices with software development, defining methodologies, writing code, and collaborating with utility planners to ensure effective product delivery.

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

Requirements:

• 4-6 years in transmission planning at an RTO/ISO or transmission utility
• You can open a base case, identify problems, run a contingency screen, and explain what the result means to a non-planner
• Comfort with AC and DC power flow, PTDF, LODF, and ATC concepts
• You have led studies (system impact, facilities, cluster, affected-system, ERIS/NRIS deliverability, or similar) and have shipped reports that other engineers signed off on
• Python proficiency
• Strong writing and presentation skills
• Experience with any of: PSS/E, PSLF, PowerWorld, TARA, PROMOD, GridView, PowerSystems.jl / Sienna
• Familiarity with IEEE 738 thermal rating calculations
• Familiarity with FERC Order 881 / AAR adoption, or active DLR programs at a utility
• Experience with LGIA, cluster studies, or affected-system studies in a WECC or MISO context
• Julia experience or willingness to learn (our power flow service is in Julia/Sienna)
• Exposure to Flutter, React, or other frontend frameworks not required, but useful for shaping how planners interact with our outputs
• Reporting / visualization experience (Plotly, HTML reports, dashboards)
• Familiarity with NERC TPL-001, MOD-032, FAC standards
