Principal Software Engineer

Technical Vision & Architecture — Guide the end-to-end architecture for the planning-to-payout lifecycle. Define the modular core primitives and the contract-driven, composable architecture that enables the edge, balancing long-term extensibility with near-term delivery. Set the engineering standards, design patterns, and technical principles for the team. Drive quality, reliability, security, performance, and cost-efficiency across services, and raise the technical bar through design reviews and architectural guidance. Represent SPCI in companywide cadences. AI-Native & Agentic Systems — Architect intelligent, agentic capabilities into the platform. Identify where AI can reduce manual toil, increase accuracy, and unlock new experiences across the planning-to-payout lifecycle. Hands-on Technical Leadership — Prototype hard problems, lead the most critical designs, and unblock the team. Mentor and grow engineers, acting as a force multiplier across the organization. Cross-Functional Influence — Partner with product management, engineering leaders, data science, design, sales operations, and finance to align technical direction with business goals. Influence without authority and unify partners around a clear technical vision and plan. Communication & Data-Informed Decisions — Communicate architecture, technical strategy, tradeoffs, and risk to executives with clarity and data-driven narratives. Define and monitor the technical health metrics — reliability, latency, quality, and engineering velocity — that prove the system is winning. Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. - Experience designing, shipping, and operating large-scale distributed systems in production, with ownership of reliability, availability, observability, data consistency, performance, and safe evolution of live services. - 8+ years of experience defining technical architecture and leading cross-team engineering initiatives. - Experience with architectural judgment in ambiguous, multi-year platform investments: decomposing complex domains into durable primitives and contracts, making trade-offs, and sequencing modernization without disrupting critical business operations. - Experience leading technical decisions across independently owned services and teams, establishing clear API and data contracts, ownership boundaries, and compatibility and migration strategies. - Communication and analytical skills, using data to build persuasive technical narratives, guide decisions, and influence leaders. - Experience to distinguishing where probabilistic AI adds value from where deterministic systems, controls, and human approval must remain authoritative. - Experience designing event-driven and workflow-oriented systems that support high-volume, business-critical processing, auditability, replay/recovery, and deterministic outcomes where financial or operational correctness matters. - Experience in cloud-native architecture (e.g., Azure), distributed systems, and data platforms. - Experience in commercial systems, including incentives, marketplaces, sales planning, financial systems, or other domains with high correctness and auditability requirements. - Experience raising architectural quality through hands-on design leadership: identifying systemic risks early, simplifying overly coupled systems, and translating design principles into adopted engineering practices.
