About The Position

At Called, we’re building the relational operating system for churches and ministries. Our platform helps ministry leaders know their people, build stronger community, and foster deeper discipleship throughout the week, not just on Sundays. We’re a small, high-trust team building meaningful software with modern tools, AI-assisted workflows, and a strong sense of mission. We move fast, care deeply about quality, and believe technology should strengthen human relationships, not replace them. If you want to help rebuild community in a disconnected world through thoughtful software, we’d love to meet you. We are looking for a Senior Full Stack Engineer, Web & Mobile to build polished, reliable experiences across the Called platform. This is a full stack engineering role with a strong emphasis on frontend development, responsive web, mobile usability, React, TypeScript, Capacitor, release quality, and user-facing craft. You should be comfortable working across the stack, but your strongest instincts should be around the user experience: how the interface behaves, how it feels on mobile, how users move through workflows, and how to ship features that are useful, reliable, and easy to use. A major part of this role will be owning the quality of our web and mobile experiences. That includes building responsive interfaces, testing mobile workflows, documenting mobile-specific issues, validating fixes, understanding app store requirements, and helping manage release workflows where applicable. We are especially excited about engineers who are AI-forward and use modern tools to move faster, prototype quickly, debug effectively, improve quality, and reduce repetitive work. This is a senior individual contributor role, not a people-management role or formal technical lead role.

Requirements

5+ years of software engineering experience, or equivalent experience building and shipping meaningful production software.
Strong experience with React, TypeScript, JavaScript, HTML, CSS, and responsive design.
Experience building high-quality interfaces for desktop, tablet, and mobile users.
Strong understanding of frontend architecture, component design, state management, data fetching, browser behavior, performance, and accessibility.
Experience testing and debugging responsive or mobile experiences across devices, browsers, and screen sizes.
Experience with mobile release workflows, app store deployment, mobile QA, hybrid mobile apps, or app-like web experiences.
Experience working with APIs and contributing across the stack, ideally with Python, Django, REST APIs, PostgreSQL, or similar technologies.
Experience using Git in a collaborative development environment.
Experience using AI-assisted development tools or agentic workflows for coding, debugging, documentation, automation, testing, or productivity.
Strong attention to detail, clear communication, and a willingness to own quality before release.
A passion for building technology that supports a mission-driven organization.

Nice To Haves

Experience with Capacitor and hybrid mobile app workflows, including testing, builds, app store submissions, and mobile release management.
Experience with React Native, Expo, Ionic, Progressive Web Apps, or similar hybrid mobile workflows.

Familiarity with Docker, AWS, CI/CD pipelines, automated testing, authentication, permissions, or role-based access control.

Responsibilities

Build and improve features using React, TypeScript, React Query, CSS Modules, Python, Django, PostgreSQL, and related tools.
Create responsive, accessible interfaces that work well across desktop, tablet, and mobile devices.
Own frontend-heavy features from planning through implementation, QA, release, and iteration.
Work with backend APIs to fetch, update, validate, and manage application data.
Contribute to backend services, APIs, data models, and integrations when needed.
Test mobile and responsive workflows across devices, browsers, screen sizes, and app environments.
Own QA for mobile issues, including reproduction, documentation, fix verification, and regression prevention.
Help manage mobile release readiness, including build validation, release checklists, app store awareness, versioning, and post-release validation.
Improve frontend architecture, component patterns, state management, data fetching, performance, accessibility, and maintainability.
Use AI-assisted tools for development, debugging, prototyping, documentation, testing, and product iteration.
Participate in code reviews, technical discussions, testing, and team knowledge-sharing.
