Mobile Software Engineer Jobs in Boulder, CO (NOW HIRING)

You'll be embedded in a product engineering team building one of LINQ's core products for parents/guardians and districts, which helps families manage student accounts - payments, balances, transaction history, and family/student management - across a React Native mobile app (your primary focus in this role), a companion web application, and a backend API.

Beyond your home product, you'll be the company's senior-most technical voice for mobile engineering. LINQ's ecosystem includes a number of native mobile applications across different products, and at a high level, you'll be the person other teams and leadership turn to when a mobile architecture, tooling, or platform decision needs to be made anywhere in that ecosystem.

As a Staff Mobile Software Engineer, you will be the primary technical owner and lead of our flagship React Native mobile application (iOS + Android), while also serving as LINQ's de facto mobile engineering lead across the broader ecosystem of native apps the company maintains. You'll set technical direction and standards for mobile development company-wide, and provide hands-on technical leadership to teams of contractors working in mobile codebases - without formal people-management responsibility, but with real authority over architecture, code quality, and technical direction.

This is a mobile-first role: your primary responsibility and the majority of your time will be spent in that flagship mobile app. As capacity and need allow, you'll also contribute to and interface with its companion web application and backend API, giving you the full-stack context to make sound mobile architecture decisions and collaborate effectively with web and backend engineers.

• Mobile Technical Leadership: Own the architecture, technical direction, and quality bar for our flagship React Native mobile application. Be the final technical voice on non-trivial mobile design decisions.
• Company-Wide Mobile Authority: Act as LINQ's go-to mobile expert across the company's ecosystem of native apps - establishing and evangelizing shared mobile engineering standards, patterns, and best practices wherever mobile development happens.
• Contractor Technical Leadership: Provide day-to-day technical leadership to contractor engineers working in mobile codebases - setting direction, reviewing code, unblocking technical problems, and ensuring their work meets LINQ's engineering bar. (This is a technical leadership role, not a people-management role.)
• Cross-Stack Collaboration: Bring mobile-informed perspective to the broader product stack, contributing to web and backend work as needed to ship end-to-end features and keep the mobile, web, and backend experiences coherent.

• Design and build robust, scalable, secure features in our flagship mobile app (React Native, iOS + Android), owning the hardest and most ambiguous mobile technical problems.
• Set and maintain mobile engineering standards company-wide: architecture patterns, code quality practices, testing strategy, CI/CD, release/versioning process, app store submission and compliance, and crash/performance monitoring.
• Provide technical leadership to contractor engineers working on mobile: reviewing designs and code, mentoring on React Native and native iOS/Android practices, and making sure contractor work aligns with LINQ's architecture and standards.
• Diagnose and resolve the most complex mobile issues - performance, stability, native module, and platform-specific (iOS/Android) problems that require deep native expertise.
• Own production health for the mobile app: monitoring, crash triage, release quality, and app store standing.
• Contribute to the companion web application and backend API as needed - enough to ship cross-stack features and represent mobile constraints/needs in web and backend design discussions.
• Influence LINQ's broader technical roadmap and strategy as it relates to mobile, partnering with engineering leadership, product, and other technical leads.
• Actively participate in agile scrum ceremonies - sprint planning, reviews, retrospectives - and help the team continuously improve its process and delivery.
• Mentor engineers at all levels on mobile development, fostering a culture of technical excellence and continuous learning.

• 10+ years of professional software development experience, with substantial depth in mobile application development.
• Bachelor's degree in Computer Science, or equivalent working experience.
• Proven, production-grade experience building and shipping React Native applications (iOS + Android) at scale.
• Real, hands-on native mobile development experience - Swift/Xcode for iOS and/or Kotlin/Android Studio for Android - not just cross-platform (React Native) experience.
• Strong proficiency in TypeScript for cross-platform mobile development.
• Demonstrated ability to lead technically - setting architecture and direction, reviewing others' work, and raising the bar for a team - including experience guiding contractors or engineers you don't formally manage.
• Experience owning mobile CI/CD, release processes, and app store submission/compliance (Apple App Store and Google Play).
• Strong understanding of mobile app performance, stability, and production monitoring (crash reporting, analytics, remote config/feature flagging).
• Experience with Git for version control and working in an Agile/Scrum environment.
• Excellent written and verbal communication skills, with the ability to communicate effectively with engineers, contractors, and leadership.
• Ability to describe, present, and influence architectural decisions across teams.

• Experience contributing to Angular-based web applications.
• Familiarity with C#/.NET, or general comfort navigating and contributing to backend/API codebases.
• Experience with common mobile SDKs used in production consumer apps: feature flagging, crash/analytics monitoring, authentication providers, and in-app support/engagement tools.
• Experience with localization/internationalization in a mobile app serving a multilingual user base.
• Experience in fintech, payments, or another domain with strong security and compliance requirements.
• Prior experience as a technical lead for distributed teams that include contractors, including cross-timezone collaboration.
