Mid-Level Software Engineer (Full-Stack - Flutter + TypeScript + Applied AI)

The role

You'll be a hands-on engineer working across our whole product: the Flutter consumer app, the AI coach and publishing platform, and the Supabase backend they share. You'll own features end to end - scoping, building, testing, shipping, and monitoring them - with a high degree of autonomy and trust.

We're hiring at mid level, deliberately: as the business grows, we want this person to grow into a senior technical leader on the product. You'll get increasing ownership of architecture decisions, internal tooling, and engineering practices as you demonstrate you can carry them.
 

What you'll actually work on

• Consumer features in the Flutter app (iOS, Android, web): the coach chat experience, the audio player, onboarding and subscription flows.
• The AI lifestyle coach - our flagship AI feature, and real agentic engineering: an LLM coach with selectable personas, long-term memory (it extracts and recalls what matters to each reader across sessions), and a toolbox of actions - recommending books, pulling chapter content, saving daily intentions and takeaways, tracking goals — with safety guardrails and context management (compaction, resumable sessions) built in. 
• The AI publishing pipeline — the machine that turns a raw book PDF into a polished, multi-language product: parsing → LLM summarization → translation → AI cover generation → ElevenLabs text-to-speech with audio stitching, orchestrated as durable, crash-safe workflows
• Backend work in Supabase: Postgres schema and migrations, Deno edge functions (payments webhooks, notifications, the coach backend).
• Internal tooling: publishing scripts, the LLM eval harness, developer-experience improvements. If a manual process annoys you, you're empowered to automate it.
• CI/CD: we run GitHub Actions, Codemagic mobile builds, and migration-validation pipelines — you'll help keep releases boring and frequent, and raise the bar on testing and deployment practice.
• AI-assisted development is how we work: we use AI coding tools (Claude Code and similar) as a core part of feature development, and we expect you to use them well — including knowing when not to trust them.
   

What we're looking for

These are our must have requirements. If you meet most of them, please apply.

• 4+ years of professional software engineering experience, including features you've shipped to production and supported afterwards.
• Strong in our two main stacks - Flutter/Dart and TypeScript/React
• Production experience with a relational database (we use Postgres via Supabase).
• Able to work independently in a remote team: you can take a loosely-defined feature, scope it, ask the right questions in writing, and drive it to done.
• Working proficiency in English (our working language).
• Degree in a STEM subject
   

Nice to have (genuinely optional)

• Supabase, or Next.js App Router experience
• Building LLM-powered features (prompting, evals, AI SDK / LangChain-style tooling)
• Mobile release experience (App Store / Play Store, Codemagic or fastlane)
• Payments and subscriptions (Stripe, Adapty/RevenueCat)
