Remote / Prague · Laravel 13 + Inertia + React
Who we are
We build APIs and tools for businesses working with creators. We're profitable, growing 30% month over month, and our founders have sold three businesses for seven figures or more.
We're expanding into a single API for multiple creator and social platforms. Customers should be able to integrate once and get consistent responses, webhooks and SDKs.
The work
Some platforms have undocumented APIs, bot detection and changes that arrive without notice. We need someone who can understand how those integrations work and keep them reliable when the platform, traffic or data changes.
We're hiring a senior full-stack engineer to keep production reliable and customer data correct. You'll plan for a workload of 50 million jobs a day, including bursts, slow upstream services and retries. You'll also build integrations and customer-facing features in Laravel 13, Inertia and React.
What you'll do
- Investigate production problems using logs, metrics and the actual request and job flow. Identify who is affected, contain the problem and verify the fix.
- Keep queues and webhook delivery reliable. Handle retries, duplicate events, rate limits and worker failures without losing data or letting one account hold up everyone else.
- Reverse engineer undocumented APIs and maintain integrations for authentication, posting, messaging, media and analytics.
- Make different platforms work through a consistent API. Keep documentation, SDKs and MCP tools aligned with the behaviour customers receive.
- Build useful dashboards and internal tools in Laravel 13, Inertia and React. Make the data accurate and the interface clear.
- Improve database queries, worker capacity and scheduling based on measurements. Add tests for the failures we cannot afford to repeat.
- Protect our APIs against abuse and check integrations when upstream behaviour changes.
- Challenge a decision when you think we're solving the wrong problem. Explain the alternative and its tradeoffs.
Production incidents and incorrect customer data take priority. We agree with the team which integration and product work comes next.
What we need from you
- You've shipped and maintained Laravel applications with real users, and you're comfortable building in React. Inertia experience helps, but is not required.
- You have operated queue or worker systems in production at substantial volume. You understand concurrency, retries, duplicate execution, backpressure and how databases and external services limit throughput.
