Principal Software Engineer

Responsibilities

-

Own the multi-year technical strategy and architectural direction for the Platform, spanning the Modeling Layer, Orchestration Layer, Trust and Compliance Layer (Identity + State Management), AI Layer, and FEDS (Frontend & Design Systems).

-

Make technology choices with org-wide impact where the right answer is ambiguous or contested — and build alignment across engineering with clear rationale and technical vision.

-

Drive architectural coherence across 7+ Platform teams, ensuring that independently-built systems compose into a unified platform with consistent contracts, APIs, and quality standards — and a developer experience that makes adoption easy for product teams. Serve as a technical leader with influence across the wider engineering organization.

-

Lead the delivery of the Platform's most impactful projects as a hands-on technical leader, with equal attention to end-customer experience and internal developer ergonomics.

-

Partner with senior EPD leadership to connect platform investments to business outcomes — tying architectural choices to customer time-to-value, product velocity, and enterprise readiness.

-

Invest deeply in coaching Staff and Senior engineers toward greater strategic scope and organizational impact.

Requirements

-

Deep expertise in platform engineering and distributed systems at scale — you've built foundational infrastructure consumed by multiple product teams and driven its evolution over years.

-

You've set and driven technical strategy at the org or company level — connecting technical choices to customer outcomes and business value across multiple teams and multi-year time horizons.

-

You lead by influence across organizational boundaries — driving alignment between teams with competing priorities without direct authority.

-

Strong written and verbal communication — you use architecture docs, strategy memos, decision records, and RFCs as everyday tools.

-

You write code, lead delivery, and stay credibly technical — hands-on excellence is non-negotiable.

Strongly Preferred

-

Experience with enterprise-scale computation or modeling platforms (spreadsheet engines, formula evaluation, financial modeling, OLAP systems).

-

Experience with state management abstractions at platform level (branching, versioning, diff/review/approve, audit).

-

Deep expertise in data orchestration: ETL pipelines, workflow engines, event-driven architectures, CDC systems.

-

Experience building and evolving complex platform architectures: API/SDK design, cross-cutting infrastructure, or developer platforms.

-

Experience designing platform capabilities with developer experience as a first-class concern — APIs, SDKs, and integration patterns where adoption is earned through usability, not mandated.

Nice to Have

• -
• Experience building AI/agent platforms, integrating AI into enterprise products, or designing API-first/MCP-compatible surfaces for agent-accessible tooling.
• -
• Experience at a B2B SaaS company during periods of significant growth or platform transformation.
• -
• Familiarity with sales performance management, incentive compensation, EPM, or adjacent enterprise domains.
• -
• Experience navigating the security, compliance, and architectural requirements necessary to build products for highly regulated industries (especially SOX and HIPAA).
