About the role
Valsnapp is looking for an experienced, independent full-stack engineer to help us improve and support a live proptech/fintech application. This is a long-term independent contractor engagement, not an employee position.
What you’ll do
- Triage and fix bugs across our application and marketing site
- Take well-scoped tickets from investigation through deployment
- Debug production issues, third-party APIs, and failed background jobs
- Maintain dependencies, address security advisories, and keep CI green
- Improve automated test coverage, including end-to-end testing
- Work directly with our technical lead through GitHub and Linear

You should be comfortable working independently in a fractional environment. We’ll provide clear priorities and technical review, but we expect you to investigate problems, communicate clearly, and move work forward without continuous supervision. This is a good fit for an experienced engineer who wants a stable, ongoing US startup client alongside other independent work. Please apply as an individual contractor, not through an agency.

- Experience deploying and debugging applications on Vercel
- Comfortable with Git, short-lived feature branches, pull requests, and feature flags
- Able to diagnose third-party API integrations, including retries, failures, and rate limits
- Writes and maintains unit/component tests and fixes failing tests rather than skipping them
- Able to reproduce user-reported bugs, identify root causes, and ship focused fixes
- Productive with AI coding tools such as Claude Code or Cursor, while critically reviewing their output
- Strong written English and ability to work independently
Strongly preferred
- Stripe subscriptions and webhooks
