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)
