About HiWox

HiWox is a HealthTech and personalized wellness intelligence company building a Healthcare Operating System (HOS) that integrates health data, analytics, evidence-based recommendations, and expert-validated wellness programs.

Our platform focuses on nine dimensions of wellness: Physical Fitness, Nutrition & Metabolic Wellness, Mental & Emotional Wellness, Sleep & Recovery, Reproductive & Hormonal Wellness, Financial Wellness, Digital Wellness, Occupational, Social & Relationship Wellness, and Spiritual Wellness.

We aim to build an explainable, data-driven wellness ecosystem that collects information from users, smartphones, wearables, healthcare devices, clinical assessments, and lifestyle inputs to generate personalised insights, recommendations, rituals, reminders, and progress dashboards.

We are looking for a Full-Stack App Developer who can take ownership of mobile and backend development, build scalable application infrastructure, and help transform the HiWox vision into a reliable, user-friendly product.

Key Roles & Responsibilities1. Mobile Application Development

Develop and maintain the HiWox mobile application, primarily using React Native or an appropriate cross-platform framework.
Build responsive, intuitive interfaces for onboarding, wellness assessments, data entry, dashboards, recommendations, rituals, reminders, and progress tracking.
Optimise app performance, accessibility, usability, and compatibility across Android devices.

2. Backend & API Development

Design, develop, and maintain backend services, REST APIs, business logic, and application integrations.
Build secure systems for user accounts, health profiles, assessments, wellness plans, notifications, and progress records.
Implement reliable authentication, authorisation, error handling, and API documentation.

3. Database & Data Architecture

Design and maintain scalable database structures for user profiles, wellness parameters, historical records, assessments, and recommendation outputs.
Establish data validation, consistency, versioning, and efficient retrieval mechanisms.
Collaborate with data scientists and healthcare experts to structure data across HiWox’s nine wellness dimensions.

4. Wellness Intelligence & Algorithm Integration

Implement rule-based algorithms and recommendation workflows developed with domain experts.
Convert structured user inputs and validated rules into explainable wellness insights, recommendations, reminders, and personalised programs.
Build interfaces and backend services that allow algorithms to evolve without requiring major application redevelopment.

5. Wearable, Device & Third-Party Integrations

Explore and implement integrations with smartphone sensors, wearables, rings, health platforms, and supported healthcare devices.
Integrate external APIs and data sources where access, technical compatibility, and user permissions allow.
Build data ingestion and validation workflows to handle missing, inconsistent, or delayed data.

6. Web Dashboards & Operational Tools

Develop web-based dashboards and administrative interfaces for wellness assessments, user progress, partner operations, and program monitoring.
Support the HiWox Captain workflow for onboarding, follow-ups, evidence collection, and coordination with consultants.
Build appropriate access controls for users, internal teams, consultants, and partners.

7. Security, Privacy & Reliability

Implement appropriate safeguards for sensitive health-related information, including access controls, secure transmission, and data protection practices.
Follow secure coding principles, maintain technical documentation, and support consent-based data access.
Conduct testing, resolve bugs, monitor application performance, and improve system reliability.

8. Product Development & Technical Ownership

Collaborate with the founder, product team, data scientists, and healthcare experts to translate requirements into working features.
Participate in architecture decisions, sprint planning, code reviews, deployment, and release management.
Help establish a maintainable codebase, reusable design systems, automated testing, and a roadmap for future scalability.

Familiarity with Git, debugging, testing, deployment workflows, and software development best practices.
Ability to independently own features from requirement analysis through development, testing, deployment, and maintenance.
Strong problem-solving, communication, and cross-functional collaboration skills.

Preferred Qualifications

Experience building HealthTech, wellness, fitness, healthcare, or data-driven consumer applications.
Familiarity with cloud infrastructure, CI/CD pipelines, analytics, push notifications, and background processing.
Experience integrating wearables, smartphone sensors, healthcare APIs, or third-party platforms.
Knowledge of secure handling of sensitive personal and health-related data.
Experience building dashboards, configurable rule engines, or personalised recommendation systems.
Comfort working in an early-stage startup where requirements evolve and engineers contribute to product decisions.

Engagement & Equity Structure

Equity-based role: No fixed salary is available at the current stage.
Commitment: Approximately 20–25 hours per week.
Work mode: Remote/hybrid, with coordination as required.
Equity participation: To be discussed based on technical expertise, responsibilities, contribution, and long-term commitment.

What You Will Build at HiWox

You will help build the technology foundation of a personalised wellness intelligence platform—not merely a standalone mobile application. Your work will connect mobile experiences, backend infrastructure, structured wellness data, explainable algorithms, device integrations, and operational dashboards into one integrated ecosystem.

We are looking for a technically strong, product-minded developer who is comfortable taking ownership, solving complex problems, and contributing to HiWox’s long-term vision as a founding team member.
