Calamba, Philippines Heard Collective Pty Ltd Full time

About Heard Heard is a trauma-informed recovery app for survivors of abuse. We provide a private, compassionate space to journal, track boundaries, and receive gentle reflections. Four of nine core features integrate OpenAI. We’re an Australian startup with a clear mission: build technology that is safe, respectful, and genuinely helpful. Content note: The work may involve exposure to sensitive topics (domestic/sexual abuse). We provide guidance and a trauma-informed culture. The Opportunity We’re hiring an experienced Flutter full-stack developer to own urgent fixes and ongoing polish on an app that’s already in market-ready shape. You’ll work directly with the founder as a right hand, ship critical improvements fast, and help set the technical tone. If it’s a great fit, there’s potential for equity participation . Engagement: Part-time to Full-time (min. 3 months) Location: Remote, Philippines (with 4+ hours overlap with AEST) Compensation: Salary (to be discussed with shortlisted candidates) What You’ll Do Triage and fix high-priority issues across Flutter (Dart) codebase (UI/UX, state mgmt, navigation, performance). Implement/repair subscription gating & free-trial flows (iOS/Android in-app purchase, entitlements). Stabilize data persistence (timelines, journaling, boundary tracker) and error handling. Integrate and harden OpenAI API features (prompting, safety rails, rate limits, retries). Ensure privacy & security best practices (PII handling, secure storage, crash/analytics config). Manage store readiness : versioning, signing, release builds (AAB/IPA), App Store/Play Console submissions. Set up/maintain lightweight CI/CD (e.g., Codemagic/GitHub Actions), QA checklists, and release notes. Communicate clearly in short daily standups; document decisions and changes. Must-Have Skills 3–5+ years professional experience; 2+ years in Flutter/Dart shipping production apps. Strong grasp of state management (Provider, Riverpod, Bloc, etc.), navigation, and responsive UI. Experience with OpenAI (or similar LLM) API integration and server-side orchestration. Android/iOS release experience: signing, provisioning, TestFlight/internal testing, store policies. Payments: In-App Purchases / Billing (trials, subscriptions, entitlements). Backend proficiency (any of: Firebase/Firestore , Supabase, Node/Express, or similar). Excellent Git hygiene, PR reviews, and issue tracking. Clear written/spoken English; proactive, reliable communication. Nice to Have Firebase suite (Auth, Functions, Remote Config, Crashlytics, Analytics). App security hardening (obfuscation, certificate pinning basics, secure storage). Experience with privacy-by-design and trauma-informed UX. Monitoring/observability (Sentry, LogRocket, Analytics funnels). Basic design sense (Figma handoff, component systems). What To Include in Your Application CV + GitHub/portfolio (Flutter apps you’ve shipped). 3–5 bullet points on relevant Flutter + IAP + OpenAI work you’ve done. A short note on availability (hours/week) and timezone overlap with AEST. #J-18808-Ljbffr
