Company Description

Frontier R&D is seeking to glorify Christ and build his kingdom through translation software. Check out https://frontierrnd.com for more information.

Role Description

We are seeking a senior backend developer to shape and implement the core architecture of LangQuest, an offline-first, open-source app that enables language data collection with AI-assisted features for low-resource Bible translation.

You'll partner directly with our lead developer to pressure-test and build large-scale designs: sync streams and partial replication (PowerSync), configurable project and process template systems, and CRDT-based approaches (Yjs/Automerge) to editing published content offline.

Qualifications

Candidates should have deep PostgreSQL experience (RLS, triggers, queues, logical replication), strong TypeScript, and real-world experience with offline-first or distributed-sync architectures — plus a research & development mindset and a passion for Bible translation and language preservation. Experience with Supabase, PowerSync (or similar sync engines), and CRDTs is a big plus. Contract cycle follows the calendar year (full-time preferred), competitive pay DOE, fully remote. To apply, email resume and cover letter to admin@frontierrnd.com.
