About Babs
Babs is building the smart operating system for modern families. Most AI tools are designed for work life, but managing home life is its own full-time job filled with coordination, communication, and constant context switching. Babs acts as a second brain that brings order to everyday life by connecting calendars, tasks, and messages into one intelligent system.  Babs is current in alpha testing, with an ambitious roadmap and vision for its public release.
Our edge is in our ability to make complex systems feel simple. Our strength is our team — driven, thoughtful builders united by a mission to bring order to everyday life and give people the clarity of an organized mind.
Our mission is to give people the power to live organized lives and organized minds that frees up the space to build joyful, connected communities. That begins with creating systems and workflows that help people feel more present and effective in their daily lives. When households run smoothly, they have more capacity to connect, contribute, and strengthen their communities.
The role
We're looking for a Platform Engineer (Backend Focus) to build and scale the systems that currently power Babs. You'll own the core platform layer that connects data, events, and AI orchestration to the user experience. The work blends deep systems design with pragmatic execution and plays a central role in making Babs reliable, secure, and trustworthy. You'll help architect a platform built for scale and designed for real-world reliability and privacy protection. Your work will transform unstructured information — messages, events, and daily logistics — into structured insight that keeps families organized and connected while safeguarding their data and personal information. You'll work across both infrastructure and product layers — designing event pipelines, real-time data flows, and automation frameworks while supporting the user-facing features that make the product feel seamless. As Babs grows, you'll help us scale to thousands of households and beyond, ensuring that performance, security, and trust remain core to how we build.
What you'll do
  • Build for performance, reliability, security, and real-time responsiveness at scale
  • Design and implement platform services such as identity, permissions, event pipelines, and data synchronization
  • Build and maintain APIs and microservices using modern backend technologies
  • Develop reliable data flows that support context-aware automation and AI agents
  • Implement and uphold best practices in security, privacy, and data protection across all layers of the stack
  • Design, build, and operate production systems end to end, from architecture to observability
  • Collaborate with product engineers and designers to ensure the platform supports elegant, intuitive user experiences
  • Improve developer experience through clear abstractions, documentation, and platform tooling
  • Help shape early engineering culture and set high standards for quality, security, and performance

  • Our ideal candidate has
  • 4 or more years of backend or platform experience in high-quality consumer or AI-powered products
  • A systems mindset and a deep understanding of how data, events, and services connect
  • Strong fundamentals in data modeling, API design, and distributed systems
  • The ability to balance startup speed with long-term production quality
  • A respect for reliability, security, and thoughtful abstractions
  • A genuine care for building technology that quietly improves people's lives

  • Bonus points for
  • Experience working with large language models or AI prompting
  • Experience implementing or auditing application security and privacy controls
  • Familiarity with designing or evaluating AI workflows and Evals
  • Exposure to distributed tracing or observability systems (such as OTEL or Datadog)
  • Experience building production-grade applications across web or mobile (such as GCP, Firebase, or React Native)
  • Understanding of modern backend frameworks and event-driven systems
  • Experience designing scalable data models or real-time data flows
  • Contributions to open-source projects or developer communities

  • Compensation & benefits
  • Competitive compensation package including equity
  • Comprehensive medical, vision, and dental insurance for you and your benefits
  • Unlimited PTO and flexible hours — we encourage everyone to take time off as needed

  • Final offer amounts are determined by multiple factors, including but not limited to experience and expertise in the requirements listed above.
    If you're excited by the idea of building foundational systems that make real life run more smoothly, we'd love to meet you — even if you don't check every box. We care about curiosity, integrity, and a shared belief in what we're building.
