Mobile Engineering Team Lead

About Rethink First

Rethink First is a leading behavioral health technology company working to make mental wellness, education, and support accessible and scalable. Through our suite of cloud‑based platforms—including Rethink Ed, Rethink Care, and RethinkBH—we serve educators, employers, and providers with tools that deliver measurable, inclusive outcomes. We're on a mission to make behavioral health more effective, equitable, and human.

We are hiring a Mobile Engineering Team Lead to own the technical direction, delivery, and quality of our native and cross‑platform mobile applications across iOS and Android. This is a hands‑on leadership role: you will write code, review code, set standards, mentor engineers, and be directly accountable for shipping. You will operate as an AI‑first engineer, leveraging Cursor, Claude Code, or equivalent tooling as a core part of your daily workflow—not as a novelty.

This is not a people‑manager‑only role. If you have not shipped production mobile code in the last 12 months, this is not for you.

• Lead a team of iOS and Android engineers through the full delivery lifecycle: scoping, estimation, architecture, implementation, testing, release, and post‑release monitoring.
• Own the mobile technical roadmap, including platform strategy, dependency management, CI/CD pipelines, release cadence, and store submission processes for both Apple App Store and Google Play.
• Set and enforce engineering standards: code review discipline, automated testing coverage (unit, integration, UI/E2E), crash‑free session targets, performance budgets, and accessibility compliance.
• Drive a test‑first culture. You are responsible for defining what “done” means and ensuring the team meets it. Expect to defend coverage thresholds and reject work that does not.
• Operate as an AI‑first engineer and require the same of your team. Use Cursor, Claude Code, Git Hub Copilot, or equivalent for code generation, refactoring, test scaffolding, and review. Establish team norms for prompt patterns, model selection, review of AI‑generated output, and where AI tooling should and should not be trusted.
• Partner with product, design, backend, QA, and Dev Ops to translate ambiguous requirements into concrete, shippable work.
• Coach and grow engineers through 1:1s, pairing, structured feedback, and performance reviews. Hire when needed.
• Be the escalation point for production incidents affecting mobile clients.

• 7+ years of professional software engineering experience, with at least 5 years building production mobile applications.
• 2+ years in a tech lead, staff, or engineering management role with direct responsibility for delivery outcomes.
• Strong, demonstrable expertise in iOS development:
  Swift, SwiftUI and/or UIKit, Combine or async/await, Xcode toolchain, App Store submission, Test Flight, code signing, and provisioning.
• Strong, demonstrable expertise in Android development:
  Kotlin, Jetpack Compose and/or the traditional View system, Coroutines/Flow, Android Studio, Gradle, Play Console, and Play Store submission.
• Deep understanding of mobile delivery: branching strategies, CI/CD (Git Hub Actions, or equivalent), staged rollouts, feature flagging, OTA configuration, and crash/analytics tooling (Crashlytics, Sentry, Firebase, Datadog, or comparable).
• Deep understanding of mobile testing strategy: XCTest, XCUITest, Espresso, JUnit, snapshot testing, contract testing, and device‑farm or cloud‑device testing (Browser Stack, Firebase Test Lab, AWS Device Farm).
• Active, daily use of AI‑assisted development tooling (Cursor, Claude Code, Copilot, Windsurf, or equivalent) with an opinion on where it accelerates work and where it introduces risk.
• Excellent written and verbal communication. You can write a clear technical design doc, run a productive standup, give direct feedback without theatrics, and explain trade‑offs to non‑engineers.

• Production experience with cross‑platforms such as Flutter (Dart, state management patterns such as Riverpod/Bloc, platform channels, plugin authoring), React Native or Ionic. Candidates who have led a native‑to‑Flutter…
