Freelance Full Stack Developer React Python Jobs in Goleta, CA

Pearly is a B2B SaaS and payments company with deep product-market fit, a hyper-modern stack, and over 2,500 dental offices on the platform. We're scaling rapidly, and continuously shipping capabilities that impact millions of users.

This is a hands-on Senior Software Engineer role weighted toward the backend and data — services, APIs, and the Postgres layer — with React frontend work as a secondary part of the job. You'll write production-grade TypeScript and SQL, owning features and initiatives end-to-end across our product domains, and use AI heavily in your day-to-day workflow.

If you're a tenacious builder who thrives on ownership, sets the bar through your own work, and is ready to help define the playbook during the excitement of the LLM era — this is your role.

Strict TypeScript, Cloud PostgreSQL, Serverless Functions, Terraform, React, GraphQL, Docker, Bun, and GitHub Actions. Strong test coverage across unit, integration, and E2E.

Each engineer works with the latest AI tools — Claude Code, Cursor, MCP, Bugbot — and we stay realistic about what LLMs can and can't do. Humans drive the specs, author collaboratively with AI, and review every layer before code hits production.

• Build backend services, APIs, and the data layer that power all of our product domains — outreach automation, payments, reporting, and analytics — with reliability and correctness as first-class concerns in a payments-critical domain.

• Own data modeling, ETL, and vendor SDK integrations across EHRs, payment processors, and external vendors.

• Contribute to the React frontend and internal tooling where your work spans the full stack.

• Raise the bar through your own example and through rigorous, constructive code review.

• Write code and documentation that guides both human engineers and AI agents toward excellence.

• Partner with Product from ideation through production release to turn business goals into clear engineering requirements.

• Author the technical specs for the initiatives you lead — thinking about scale, edge cases, and long-horizon maintainability.

• Contribute to CI/CD, GitHub Actions, Terraform, and development infrastructure as needed, including improvements to the tooling and check systems the team relies on.

• Computer Science or similar quantitative / technical / engineering degree, or equivalent practical experience.

• 5+ years deploying to production, with direct responsibility for high-scale platforms (100M+ records) in an accuracy-sensitive domain like healthcare or fintech.

• Deep experience building backend and data systems (services, pipelines, APIs) in a general-purpose language and SQL, with strong relational data modeling fundamentals.

• Extensive experience in TypeScript or a strongly typed language; comfortable in React, though frontend is the smaller part of this role. You think natively in terms of type safety and test coverage.

• Familiarity with a major cloud provider (GCP, AWS, or Azure).

• Understanding of security and compliance requirements for PHI, PII, and financial data.

• Based in New York, NY; Santa Barbara, CA; or Atlanta, GA.

• Relentless executor: You drive projects to completion with urgency and long-horizon accountability. You handle initiatives end-to-end, know your blind spots, and know when to pull in the right people.

• Architectural thinker: You see the patterns behind the problems — designing systems and abstractions that hold up at scale and over time. You seek out simplicity and elegance.

• Revenue-aware: Reliability, accuracy, and scale aren't abstract goals — they're the product.

• Competitive salary, equity, and healthcare benefits

• Meeting-light culture

• Work with high-talent, high-integrity people who genuinely enjoy the art of building and competing

• Flexible vacation / time-off policy
