About our hiring partner

Our hiring partner is modernizing end-of-life services with compassion, transparency, and simplicity. They help families make cremation arrangements online or over the phone—providing a kinder, clearer alternative to the traditional funeral home experience. They\'re growing quickly, now serving families in over 15+ markets across 10 US states, and backed by top-tier investors.

The Role

Our hiring partner is hiring a Senior Software Engineer to drive product and growth initiatives across their customer-facing web experiences. You\'ll work closely with their Head of Product and Chief Revenue Officer to design, build, and optimize flows that help families discover, choose, and manage their at-need and pre-need arrangements—think onboarding, quotes, checkout, account management, referrals, retention, lifecycle touchpoints and more.

You\'ll be a hands-on full-stack builder who enjoys collaborating across teams, iterating quickly, and shaping impactful experiences that drive measurable growth.

What You\'ll Do

• Design, build, and ship full-stack features in their customer web app and growth surfaces.
• Collaborate with product and revenue leadership to ideate, run, and analyze experiments (funnels, pricing/packaging, referral loops, lifecycle nudges, onboarding, and conversion optimizations).
• Build and refine product flows that help families make confident, informed decisions.
• Instrument analytics and event tracking to ensure clear, causal measurement of impact.
• Contribute to a fast feedback loop: quick prototypes → data-informed iteration → polished releases.
• Uphold reliability, accessibility, performance, and security across the stack.

What We\'re Looking For

• 5+ years as a full-stack product engineer in startup or growth-oriented environments.
• Strong proficiency with React, TypeScript, and Node.js.
• Proficiency with AI-assisted software development practices (e.g., Cursor, Copilot, CLI tooling, or other AI development accelerators).
• Experience or strong interest in building AI-powered or agentic product functionality.
• Product intuition—you care about why we\'re building something, not just how.
• Ability to translate product goals and user insights into elegant, pragmatic technical solutions.
• Comfortable working autonomously, owning projects end-to-end, and partnering cross-functionally.

Bonus (but not required)

• Experience with Firestore/Firebase, PostgreSQL, Elasticsearch, Pub/Sub or event-driven architectures, Google Cloud, BigQuery, or Redis.
• Familiarity with growth tooling and experimentation frameworks (e.g., PostHog).
• Background in consumer web apps with complex flows, payments, or subscriptions.

Why Join

Meaningful mission—your work directly supports families during one of life\'s hardest moments.

High impact and ownership—tight collaboration with leadership on product & growth strategy.

A small, talented team that moves quickly, values craftsmanship, and avoids unnecessary process.
