Location: Surat / Ahmedabad (On-site)

Employment Type: Full-time

About the Company

We are an AI-driven nutrition platform built to make healthier eating and living effortless. We translate ingredients and dishes into reliable nutrition profiles, then personalize recommendations based on goals, context, and preferences—across home cooking, daily routines, and restaurant ordering.

Our technology includes Flutter mobile apps, a Python/Django API, real-time data services, and machine learning models for tagging, ranking, and predictions. We’re building a delightful, safe, and scalable experience that helps users choose better meals and track progress—with strong standards for privacy, quality, and performance.

Role Summary

As the Tech Team Lead, you will lead a cross-functional engineering squad (Flutter, Backend, QA, and occasionally Data) to deliver secure, scalable product features on predictable timelines. This role combines hands-on architecture and coding with team leadership, agile execution, and quality ownership.

You’ll mentor engineers, improve engineering practices, and collaborate closely with Product and Design teams to ship impactful, user-centric experiences.

Key Responsibilities

• Own squad roadmap delivery — break down epics into milestones, estimate efforts, prioritize, and ensure timely releases.
• Provide technical leadership — define architecture, enforce coding standards, and guide trade-offs between performance, cost, and complexity.
• Contribute 30–50% hands-on coding — review critical PRs, pair program, and work on key modules.
• Ensure quality and reliability through robust testing (unit/integration/E2E), CI/CD gates, observability, and incident management.
• Mentor and manage 4–8 engineers — conduct 1:1s, set goals, and drive performance and career growth.
• Maintain security and compliance — apply secure development best practices (AuthN/AuthZ, PII handling, secret management).
• Collaborate with Product/Design on scope and acceptance criteria; communicate status, risks, and dependencies effectively.
• Keep technical documentation up to date — architecture decisions, system diagrams, runbooks, and release notes.

Required Qualifications

• 6–9+ years of software engineering experience, with at least 2–3 years in team/squad leadership.
• Strong backend expertise in Python, Django/DRF, REST API design, caching, queues, and WebSockets.
• Working knowledge of Flutter/Dart architecture and state management to lead cross-stack initiatives.
• Experience with CI/CD (GitHub Actions, Fastlane, Codemagic), containers (Docker), and AWS (EC2/ECS/ECR, S3, CloudFront, CloudWatch).
• Strong testing culture using PyTest, Flutter Test, and observability tools (logs, metrics, tracing, alerts).
• Excellent estimation, prioritization, and communication skills, with the ability to challenge scope when necessary.

Preferred (Nice to Have)

• Experience releasing and managing mobile apps (Play Console, App Store Connect, TestFlight).
• Exposure to Data/ML pipelines (batch vs. real-time inference, model versioning).
• Familiarity with security practices — OWASP, IAM, secret management, VPCs.
• Domain experience in health-tech or food-tech, or other privacy-sensitive industries.

Tech Stack You’ll Work With

• Mobile/Web: Flutter (Dart), React (optional)
• Backend: Python, Django/DRF, Celery, Redis, WebSockets
• Data/Storage: PostgreSQL/MySQL, MongoDB
• Infra/DevOps: AWS (EC2/ECS/ECR/S3/CloudFront/CloudWatch), Docker, Nginx, GitHub Actions, Fastlane, Codemagic
• Quality/Observability: PyTest, Flutter Test, Playwright/Cypress, Sentry, Crashlytics, OpenTelemetry (optional)
