About the job

A NauWork client is seeking a Senior Software Engineer to join their team. The position may be on-site or hybrid in Seattle, Washington , or fully remote with travel to Seattle at least once per month.

This early-stage technology company is creating a new category of flexible, on-demand childcare and household management. Its platform connects families with vetted caregivers through intuitive experiences across web, mobile, and text, making support easier to arrange while helping caregivers build meaningful careers. AI agents, large language models, and thoughtfully designed software power the complex marketplace behind that simple experience. With an established presence in Seattle and plans to expand into new cities, the company offers an opportunity to help shape a high-impact product from the ground up.

This is a rare opportunity to work as a full-stack builder, product thinker, and AI researcher in one role. The Senior Software Engineer will own core product interfaces and AI infrastructure, take features from prototype through production, and influence foundational decisions about architecture, tooling, and engineering culture. Working closely with the founding team, this person will balance rapid experimentation with the security, scalability, and reliability that families and caregivers depend on. As the company grows, they will also help build and lead the engineering team while establishing the technical foundation for an intelligent care platform.

Responsibilities:

Build the core product: Own AI infrastructure and feature development end-to-end, from prototypes to production-ready systems that customers rely on. Pay close attention to the data and user feedback to know what to build.

Shape technical direction: Make foundational decisions on architecture, infrastructure, and tooling.

Move fast: Ship experiments, iterate on feedback, and balance speed with maintainability.

Collaborate closely: Work hand-in-hand with the founding team across product, design, and growth.

Ensure reliability: Build secure, scalable systems that families can trust with their most important needs.

Lay the foundation for scale: Establish engineering best practices, documentation, and culture. Eventually help build and lead the engineering team.

Required Experience:

5+ years of professional full-stack and AI engineering experience (backend + frontend).

Proven experience building production systems with modern frameworks.

Hands-on experience building AI-powered product features—LLM and agentic workflows, prompt engineering, retrieval, and evals—alongside databases, APIs, and third-party integrations in high-availability production systems.

Ability to work full-time, on-site/hybrid in Seattle, WA. If remote, you’re able to travel at least once per month.

Strong product sense where you care deeply about user experience and balance user needs with technical constraints to ship simple, magical products.

Demonstrated ability to execute quickly in ambiguous environments.

Experience with React/Next.js, TypeScript, Postgres, OpenAI/Anthropic, Inngest, Evals, and Agentic AI.

A builder at heart: You thrive on taking ideas from 0 to 1, wearing many hats, and turning vision into reality.

Obsessed with growth: You set the bar unreasonably high and push far past “good enough” to deliver exceptional results.

Driven by outcomes: You’re not looking to clock out of work. You’re willing to flex, adapt, and put in the work required to build and grow the company.

Courageous: You run at resistance and find energy where others hear “no.” Obstacles motivate you.

Execution-first: You believe trust is earned by shipping beautiful, functional, and reliable products.

Fast-moving: You thrive in speed and ambiguity, creating clarity instead of waiting for it. You learn, adapt, and improve quickly.

Creative and daring: You challenge conventions, reimagine what’s possible, and infuse delight into the everyday.

Ruthlessly focused: You know how to cut through noise and relentlessly prioritize the one thing that truly moves the needle.

Preferred Experience:

iOS or cross-platform mobile app development experience via React and Expo.

Knowledge of security best practices in consumer applications.

Prior startup or 0-to-1 product experience. Former or future founders preferred!

Experience working with LLMs and AI-driven products in a production environment, including self-hosting and tuning models and running evals.

You love building consumer or family-related products.

You’re a parent or have been a nanny/caregiver!
