The Mission Tonomo is revolutionizing e-commerce with an intelligent, autonomous platform powered by IoT and AI. We are in the Beta phase, rapidly iterating based on user feedback. We need an "Unblocker"—a senior engineer who owns the mobile experience but can dive into the Python backend to build the endpoints they need to move fast.

The Engineering Culture We believe in AI-Augmented Engineering. We expect you to use tools like Cursor, Copilot, Gemini, GPT-4 and alike, to handle boilerplate code, allowing you to focus on complex native bridges, system architecture, and "on-the-spot" bug resolution.

Core Responsibilities

• Flutter Mastery: Lead the development of our cross-platform Beta app (Android, iOS, and Web) using Flutter.
• Backend Independence: Build and modify REST APIs and microservices in Python (FastAPI) to unblock frontend features.
• AI coding: tools like Cursor, Copilot, Gemini, GPT-4 and alike
• Agile Troubleshooting: Fix critical UI and logical bugs "on the spot" as reported by users. Experience with UI/UX best practices.
• Performance & Debugging: Proactively monitor app health, experienced with Sentry, Firebase Crashlytics, and Flutter DevTools
• IoT & Integration: Work with IoT telemetry protocols (MQTT) and integrate third-party services for payments (Stripe) and Firebase.
• Native Depth: Develop custom plugins and MethodChannels to bridge Flutter with native iOS/Android functionalities.
• Dashboard Ownership: Own dashboards end-to-end. Design and build internal dashboards for: Business Intelligence. System health and operational metrics. IoT and backend activity insights.
• Frontend Development Build modern, responsive web dashboards using React (or similar). Implement advanced data visualizations. Focus on clarity, performance, and usability for non-technical stakeholders.
• BI & Data Integration: Integrate dashboards with: Backend APIs (Python / FastAPI). Databases (PostgreSQL). Analytics / metrics sources (Grafana, Prometheus, or BI tools). Work with product & ops to define what should be measured.
• Monitoring & Insights: Build visual views on top of monitoring data (Grafana or embedded views). Help translate raw metrics into actionable insights. Support ad-hoc analysis and investigation workflows.
• Execution & Iteration: Move fast in a startup environment: iterate dashboards based on real feedback. Improve data quality, consistency, and trust over time.

Technical Requirements

• Mobile Experience: 7+ years in mobile development with at least 5 highly distributed apps published.
• The Stack: * Frontend: Expert Flutter/Dart skills
• Backend: Proficient Python developer with experience in FastAPI, SQLAlchemy, and PostgreSQL.
• Data & Backend Awareness: Comfortable consuming REST APIs and working with structured data.
• Ability to collaborate on schema design and API contracts.
• BI / Analytics (Nice to Have): Experience with BI tools or platforms (Grafana, Metabase, Superset, Looker, etc.).
• Understanding of KPIs, funnels, and business metrics.
• Experience embedding dashboards or analytics into web apps.
• Architecture: Mastery of design patterns for both mobile (MVVM/MVC) and backend microservices.
• Infrastructure: Experience with Google Cloud Platform and IoT telemetry (mandatory).
• Execution: Proactive attitude toward learning and the ability to "own" a feature from DB schema to UI implementation.
• Experience with Atlassian Jira

Soft skills:

·      Self-Directed Ownership: flags blockers early and suggests improvements without being asked. You are well experienced professional... You don't wait for a Jira ticket to be perfect; you ask the right questions and move the needle forward

·      Transparency: Extreme honesty about timelines—if a task is more complex than estimated, you communicate it immediately, not at the deadline.

·      Clear communicator with engineers and non-technical stakeholders.

The Deal

• Part-time Retainer: 100 hours per month.
• Rate: $15 – $18 USD per hour (Performance-based).
• Impact: Direct partnership with the founding team in a fast-paced, AI-driven startup.
• Location: We value the stability and focus of Tier-2 rockstars Kochi, Indore, Jaipur, or Ahmedabad and alike.
