Staff Software Engineer, Modeling Platform

CaptivateIQ is transforming how companies plan, manage, and optimize sales performance through its incentive compensation and sales planning platform. The Staff Software Engineer will own the technical direction and multi-year strategy of the Modeling Platform, including its framework, SDK, APIs, frontend components, and AI-native interfaces, while driving cross-team alignment and mentoring engineers.

Responsibilities:

• Own the technical direction of the modeling platform's framework and SDK layer, partnering closely with the SmartGrid team on the underlying computation engine
• Own and evolve the platform's framework, SDK, and interfaces — including agentic/tool-based interfaces for AI consumers — turning today's API surface into a self-service framework with the extensibility points that let internal teams build modeling products fast
• Make the platform-level tradeoffs that shape it: what belongs in the framework vs. a product team's responsibility, build vs. buy, refactor vs. patch, flexibility vs. opinionated speed
• Operate with high ownership and autonomy — drive ambiguous or contested decisions forward by pulling in the right stakeholders early rather than letting them stall, and own the outcomes months later, good or bad
• Set the multi-year technical strategy for the modeling platform, in partnership with your EM, PM, Design, and senior EPD leadership
• Drive technical alignment across teams — build the credibility and relationships that align consuming product teams around the platform's roadmap
• Stay hands-on as a backend-primary fullstack engineer — the platform spans backend APIs, SDKs, and the frontend components product teams extend and build modeling experiences on top of
• Grow and develop engineers on the team — coach toward senior and staff-level impact, set the technical bar through design leadership and review standards, and provide architectural guidance that scales beyond your own output
• Participate in an on-call rotation to provide after-hours support, ensuring timely resolution of critical issues and maintaining system uptime

Requirements:

• 8+ years of professional software engineering experience with progression into staff-level technical leadership
• Strong Python fundamentals with production experience in Django or similar Python web frameworks
• Demonstrated experience owning a platform or framework layer — not just a service — that multiple internal teams built on top of
• Strong backend engineering foundation with hands-on experience building frontend components that other engineering teams consume, extend, and build on top of
• Track record of setting multi-year technical strategy for a platform or major system, with evidence of the strategy shipping and delivering impact
• Track record of growing engineers to the next level — mentoring, coaching, and leading their technical development toward senior and staff-level impact
• Familiarity with Go, for collaboration with the SmartGrid computation engine team
• Experience designing interfaces for AI agent consumption — tool-use schemas, MCP-style protocols, structured function-calling interfaces
• Familiarity with columnar data formats (Apache Arrow, Parquet) and OLAP storage engines (ClickHouse, DuckDB, or similar)
• Working knowledge of DAG-based or dependency-graph-driven computation systems
• Experience designing SDKs or self-service developer platforms consumed by multiple internal teams
• Experience at a B2B SaaS company during periods of significant growth or platform expansion
• Familiarity with sales performance management, incentive compensation, or adjacent enterprise domains
