Senior Full-Stack Engineer (Python / SvelteKit / Kotlin Multiplatform)

Palantis seeks a Senior Full-Stack Engineer for a remote full-time role. Salary: $3,000–$5,000/month. Build Python/FastAPI backend, SvelteKit frontend, and Kotlin Multiplatform mobile app; 5+ years experience required.

Develop features across the stack: backend on FastAPI, frontend on SvelteKit. Build a mobile app on Kotlin Multiplatform: a native shell around the web frontend with a typed JS-native bridge, Microsoft SSO and biometric auth, and platform integrations. Design async APIs, data models, migrations, and background tasks (recurring schedules, activity feeds, notifications). Create MCP tools that make the product available to AI agents. Keep the codebase strict: end-to-end typing, tests, and small reviewable MRs.

5+ years of production application development. Confident in both Python and TypeScript, and solid in Kotlin. Able to own a feature independently: backend, frontend, tests, deployment. Working English for code reviews and documentation. Deep immersion in LLM work expected: experience building agents, skills, harnesses. Nice to have: MCP / LLM-agent integrations in production; Swift / iOS as the iOS target grows in the KMP app; Web push, WYSIWYG, and rich-text editors.

Remote work format. Full-time employment. Salary: $3,000–$5,000 per month.
