Full Stack Developer

About JARK Technologies

JARK Technologies builds AI and IoT products. We are a small, senior team, and you will have direct access to our founders and our CTO.

What we are building:We are building a physician-led AI wellness companion. Members talk to an AI companion about their health goals, move through a guided onboarding and a personal journey, and are matched with partner clinics for consultations and follow-up. The platform has a member mobile app, a web portal for partner clinics, and the AI chat and integration services behind them. We are taking it from a validated prototype to a production launch in a HIPAA-regulated setting.

This job is currently remote with a planned in-office transition to Pune, Maharashtra.

About the job

The role:You will build the product's member app and the Python services behind it, end to end: onboarding and sign-in, profile, journey and appointment booking, from the screen to the database, to production quality on iOS and Android.

• What you will own: App, onboarding: sign-in, OTP entry with autofill, consent flows, account deletion and permission prompts (notifications, location, Apple Health or Health Connect), with every state built: loading, empty, error and offline.
• App, chat and journey: The chat interface (streaming replies, message states, quick-reply chips, rich cards, conversation history and resume), plus the journey timeline, profile, goals, care team and connected devices.
• App, booking: Slot picker, review, confirmation, cancel and reschedule, and add to calendar.
• App, release engineering: Expo builds, TestFlight and Play internal testing, store submissions with privacy labels and data-safety forms, staged rollouts and feature flags, crash monitoring and analytics events.
• Backend, identity and access: OTP login, session and token lifecycle, authorization on every endpoint, account recovery and account deletion.
• Backend, data: PostgreSQL schemas and migrations for members, onboarding state, profile, journey events, consent records, appointments and notifications, with encryption and audit logging for sensitive actions.
• Backend, booking and integrations: Scheduling services and connectors to partner clinic systems, with idempotent workflows, webhooks with a polling fallback, and rate-limit handling.
• Quality: Unit, integration and end-to-end tests, CI gates, documented APIs, and close work with the QA engineer and the designers.
• Clinic portal: React screens and API support as the portal moves to production.

What we are looking for:

• 3+ years of engineering, including 2+ years in React Native with TypeScript and 2+ years building Python backends (not scripting).
• Apps shipped to both the App Store and Google Play, with Expo and native modules, navigation, state management and data fetching.
• Network resilience: streaming (server-sent events or WebSockets), retries and offline queues.
• Authentication and authorization design: sessions, tokens, OAuth2 or JWT, and safe handling of secrets and personal data.
• Solid PostgreSQL design and migration experience.
• Workflows that are idempotent and safe to retry, such as bookings and payments.
• Accessibility basics: Dynamic Type, VoiceOver and TalkBack.
• A habit of testing at several levels and shipping behind CI.

Nice to have:

• HealthKit, Health Connect and wearable SDKs.
• Health or other regulated data, HIPAA awareness, and store privacy requirements.
• React on the web, and building or maintaining a design system.
• Third-party scheduling, EMR or payment API integrations, with FHIR or HL7 a plus.
• SMS and OTP providers.
• Animation with Reanimated, Lottie or Skia.

How we work:

Weekly sprints, architecture set with the CTO, designs approved before build, small pull requests with review, demos of the real build, and a QA engineer working beside you from the first week.

What success looks like:

• Onboarding that works end to end on every supported device, from OTP to the first conversation, with every state handled.
• Authentication and data handling that pass an external security review.
• A predictable release cadence to TestFlight and Play internal testing.

Job description

Build useful integrations across application APIs, AI tools, workflow systems and user interfaces. You will combine TypeScript/Node.js and React development with MCP, tool-using agents and low-code workflows that include custom code.

You will work with a backend lead, an Android automation engineer and a browser automation engineer. The role includes improving existing interfaces, connecting reliable data to dashboards, and turning routine operational tasks into maintainable, observable workflows. Company-provided AI coding tools support development.

Responsibilities

- Build and improve TypeScript APIs, React interfaces and integrations with existing services.

- Maintain existing Python/FastAPI APIs and background jobs, with support from the backend lead on architecture and database changes.

- Implement MCP tools and agent workflows with defined inputs, permissions, failure handling and useful evaluation cases.

- Connect low-code workflows to APIs using webhooks, authentication and custom JavaScript or Python.

- Make workflows reliable through idempotency, retries, execution logs and clear recovery behaviour.

- Build curated analytics feeds and dashboards, checking that displayed results agree with source data.

- Improve selected slow or broken frontend journeys using profiling, tests and user-facing acceptance criteria.

- Document plans before implementation and attach verification evidence to completed tasks.

Required skills and experience

- Production TypeScript/JavaScript, Node.js, React and API integration experience.

- Working Python/FastAPI skills sufficient to diagnose, change and test existing APIs and asynchronous jobs.

- Hands-on experience shipping tool-calling AI features or MCP integrations, with the ability to explain authorisation and failure cases.

- SQL/database fundamentals, authentication, webhooks and asynchronous processing.

- Practical testing, Git review, debugging and safe handling of credentials and sensitive data.

- Clear written English for specifications, prompts, task updates and review responses.

- Evidence of maintaining an integration after release and correcting problems based on feedback.

Experience with BI dashboards, incremental data feeds and agent evaluation is useful. You should be able to explain how a result was checked and when the system should report uncertainty or request human input.
