Senior Full Stack Engineer, Web & Mobile

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.

What You'll Do

• 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.

Do you have experience in System architecture design?, * 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.

People Who Thrive Here

• Senior individual contributors who enjoy ownership without needing a management title
• Full stack engineers whose strongest instincts are frontend, mobile, and user experience
• Builders excited by AI and modern engineering workflows
• Product-minded engineers who think beyond the ticket
• Team players with low ego and high standards
• Engineers who can move across the stack without treating user experience as an afterthought

Bonus Skills

• 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.
• Experience with mobile-first design, design systems, component libraries, or reusable frontend patterns.
• Familiarity with Docker, AWS, CI/CD pipelines, automated testing, authentication, permissions, or role-based access control.
• Experience building AI-powered product features or internal AI developer workflows.

Newman Ministry is an equal opportunity employer. All qualified applicants will receive consideration for employment.

Our platform helps ministry leaders know their people, build stronger community, and foster deeper discipleship throughout the week, not just on Sundays. Most churches serve hundreds, if not thousands, of people. Yet very few people in these communities feel truly known. People often drift away not because they reject belief, but because nobody notices they disappeared. 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 believe modern engineers should be dramatically amplified by AI. Our team actively uses AI-assisted workflows for development, debugging, prototyping, testing, documentation, automation, and rapid product iteration. We care far more about builders who can move fast, learn quickly, and solve problems than developers obsessed with rigid specialization. We value: * Ownership over bureaucracy * Shipping over perfectionism * Curiosity over ego * Product thinking over ticket completion * Mission and craftsmanship equally
