Principal Software Engineer (PMTS), Full Stack

About the role

The Role

As a Principal Engineer on the Product Team, you’ll set technical direction for broad, business-critical areas of the product and drive execution across multiple teams and stakeholders.

You’ll take the most ambiguous, highest-leverage problems—where the right approach is not obvious—and turn them into durable systems, scalable architectures, and repeatable delivery patterns.

You’ll partner with product and design leadership to shape strategy and roadmap, and you’ll translate goals into clear technical plans, milestones, and success metrics.

You’ll also help us translate emerging AI capabilities into practical, reliable product experiences—choosing the right techniques for the job, designing clean interfaces between AI components and the rest of the system, and ensuring the resulting features are observable, testable, and maintainable.

Responsibilities

• Define and drive technical strategy for major product areas, ensuring long-term scalability, reliability, and developer velocity
• Lead large, cross-team initiatives from concept through launch and iteration (including sequencing, dependency management, and stakeholder alignment)
• Architect and evolve complex systems spanning frontend, backend services, and data models; make pragmatic tradeoffs that optimize for customer outcomes and operational excellence
• Establish and evolve engineering standards (architecture patterns, testing strategy, performance budgets, reliability/observability practices) that scale across teams
• Build AI-powered experiences using LLMs, embeddings, and related techniques where they create real user value, with strong engineering around evaluation, observability, and iteration
• Proactively identify and eliminate systemic risks: reliability gaps, performance bottlenecks, scaling constraints, and operational toil
• Mentor and develop engineers across levels; amplify impact by coaching technical leaders and raising the bar for design and execution
• Communicate clearly and influence effectively across engineering, product, design, and leadership—especially during high-ambiguity decisions

Requirements

• Deep experience shipping and operating production full-stack web applications at scale
• Demonstrated ability to set technical direction and drive alignment across multiple teams or workstreams
• Strong track record delivering large, complex initiatives with meaningful dependencies and cross-functional stakeholders
• Strong systems thinking: you can reason about architecture, performance, reliability, and developer experience as a cohesive whole
• Hands-on experience applying AI/ML in product (LLMs, embeddings, or similar), with strong judgment about evaluation, safety/reliability, and user trust
• Comfortable operating in ambiguity and creating clarity: framing problems, defining approaches, and making decisions that stick
• Strong communicator: you can write and speak clearly to different audiences and drive decisions through influence
• Product-minded: you care about UX and customer outcomes, not just implementation
• Ownership mindset and bias for action
• Experience with modern web frameworks (Rails/React/Postgres/AWS is a plus; adaptability matters most)

Qualifications

• Nice to Have: Experience with enterprise SaaS (especially B2B marketing or sales tech), experience with real-time systems (chat, messaging, event-driven), familiarity with Salesforce/CRM integrations, experience building agentic systems or autonomous tool-using workflows, experience defining reliability practices (SLIs/SLOs), incident response improvements, or observability standards, Startup experience and rapid shipping

Skills

• Experience with modern web frameworks (Rails/React/Postgres/AWS is a plus; adaptability matters most)
