Job description

Note: By applying to the Senior / Lead Software Engineer - Full Stack posting, recruiters and hiring managers across the organization hiring software engineers will review your resume. Our goal is for you to apply once and have your resume reviewed by multiple hiring teams.

About the Product Team

As a Software Engineer on the Product Team, you’ll turn ambiguous product problems into high-quality shipped software - partnering closely with product and design to define what we build, how we build it, and how we measure success. You’ll work on the core workflows that matter most to customers, from the UI they touch every day to the backend services and data models that power them. You’ll also help us translate emerging AI capabilities into practical, reliable product experiences. That means choosing the right techniques for the job, designing clear interfaces between AI components and the rest of the system, and ensuring the resulting features are observable, testable, and maintainable. If you enjoy moving from concept to implementation quickly - and iterating based on real usage - this role is built for that.

What You’ll Do

• Ship full-stack product features end-to-end across frontend, backend, and data
• Build AI-powered experiences using LLMs, embeddings, and related techniques where they create real user value
• Own delivery from scope/design through launch, monitoring, and iteration
• Solve ambiguous, technically challenging problems with pragmatic, scalable solutions
• Partner closely with product, design, and engineering to shape requirements and roadmap
• Improve performance, reliability, and overall product quality at enterprise scale
• Contribute to strong engineering culture through code review, tooling, and process improvements

Who You Are

• Experience: 5+ years of experience in professional software development
• Proven experience shipping production full-stack web applications
• Hands-on experience applying AI/ML in product (LLMs, embeddings, or similar)
• Comfortable operating in ambiguity and driving work forward independently
• Product-minded: you care about UX and customer outcomes, not just implementation
• Strong communicator and collaborator across functions
• Ownership mindset and bias for action
• Experience with modern web frameworks (Rails/React/Postgres/AWS is a plus; adaptability matters most)
• Curious and continuously learning

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
• Startup experience and rapid shipping

Why Us?

• Build real product with real impact: Ship customer-facing features that directly improve pipeline generation and the day-to-day workflows of go-to-market teams at major enterprises.
• Work across the full stack: Own meaningful slices of the product across frontend, backend, and data - optimizing for speed, quality, and maintainability.
• AI as a core product surface: Help turn new AI capabilities into dependable experiences that customers trust, with strong engineering around evaluation, observability, and iteration.
• High bar, low bureaucracy: Work with a team that values craft and decisive execution, where strong ideas win and shipping is the default.
• Room to grow: Take on larger technical and product scope over time - leading projects, influencing architecture, and leveling up quickly.
