Founding Product Engineer Scottsdale, AZ (In Person Preferred) | Full-Time | $10,000/month Help Build the Future of Real Estate Real estate is one of the largest industries in the world, yet most brokerages still rely on disconnected software, spreadsheets, manual processes, and inconsistent coaching to develop their agents. We're changing that. PCx is building the operating system for real estate organizations: a single platform that brings together onboarding, training, coaching, performance management, business planning, accountability, AI, and leadership into one modern experience. Our mission is simple: Help brokerages develop better agents, faster, at scale. We've already invested heavily into building the platform and have an experienced overseas development team. We're now looking for a Founding Product Engineer to become our technical leader in Arizona, someone who can own the product, move quickly, make smart technical decisions, and help build a world-class software company. This isn't a corporate engineering job. This is an opportunity to help build something meaningful from the ground up. About the Role You'll work directly with the founder to translate product vision into exceptional software. You'll be expected to think like both an engineer and a product leader, understanding the business, improving the product, writing production code, reviewing architecture, and helping lead development across our engineering team. We're looking for someone who enjoys solving hard problems, moving fast, and taking ownership. Responsibilities * Lead development of our SaaS platform alongside an existing engineering team * Write high-quality production code across the full stack * Design scalable architecture and technical solutions * Review code and maintain engineering standards * Translate product ideas into technical implementation plans * Collaborate directly with the founder on product strategy and roadmap * Improve user experience through thoughtful product decisions * Build and integrate AI-powered features using modern LLM technologies * Help hire, mentor, and grow the engineering team over time * Continuously improve platform performance, scalability, and reliability Ideal Experience * Strong experience building modern SaaS applications * Expert with React, TypeScript, Node.js, and PostgreSQL * Experience designing scalable software architecture * Experience working with cloud infrastructure (AWS preferred) * Familiarity with AI technologies, OpenAI APIs, and LLM-powered applications * Startup experience or a desire to build in a fast-moving environment * Strong communication skills with the ability to explain technical decisions clearly * Willing to work from or relocate to Scottsdale, Arizona What Success Looks Like Within your first year, you'll become the technical leader behind a platform with the potential to transform how thousands of real estate professionals learn, grow, and build their businesses. As the company grows, this role's salary will grow proportionally, and quickly. If you're looking to move fast and make a meaningful change in both the real estate industry, and eventually other sales industries, lets talk.

I am a licensed therapist building a web app that helps therapists and clients be more connected with homework throughout the week. The app was built using Lovable (an AI app builder) and I need an experienced healthcare developer to review what was built, clean it up, fix any security gaps, and confirm it meets HIPAA technical requirements. This is a startup-stage project. I am the sole founder. I need someone who can communicate clearly with a non-technical person and explain what they find and why it matters. What I Need You To Do: Review all code generated by Lovable and identify security vulnerabilities Confirm or fix data encryption at rest and in transit Review every third-party service or vendor the app connects to and flag any that would require a Business Associate Agreement (BAA) Confirm that client-entered content (homework reflections) cannot be accessed by any unauthorized party Ensure the therapist and client login system is secure and roles are properly separated Confirm that the permanent crisis support button on all client-facing screens cannot be removed, bypassed, or overridden Provide a short written summary of what you found, what you fixed, and what still needs attention What This App Does NOT Do: No billing or insurance No video or scheduling No AI responding to client content No users under 18 What I'm Looking For in You: Demonstrated experience building or auditing HIPAA-compliant SaaS applications Familiarity with BAA requirements and which vendors (cloud hosts, email services, AI APIs) typically require them Experience with web apps built on modern frameworks (React, Next.js, or similar) Ability to explain technical findings in plain English Bonus: experience with mental health, therapy, or healthcare technology specifically To Apply, Please Answer These Three Questions: 1. Describe a HIPAA-compliant project you have worked on. What was the app, what did you build or audit, and what vendors required BAAs? 2. What is your process for reviewing code built by an AI tool like Lovable or Bolt? 3. What is one common HIPAA technical safeguard that early-stage health app developers frequently miss? Applications that do not answer all three questions will not be considered. This app handles real therapy client data. I take privacy and safety seriously and I am looking for someone who does too, not just someone who can write compliant-sounding documentation. Please only apply if you have genuine healthcare tech experience.

I need a React Native developer to help complete and stabilize my social media app, QueFlic, before QA and beta launch. This is not a full rebuild. The app is already built, but it needs missing flows completed, smoother user experience, error handling, and final pre-QA fixes. The app is a social media platform with photo posts, video posts, Live Photo posts, music/location/tag overlays, WordBox polls/Q&A/reactions, comments, messaging, and sharing. Main work needed: 1. Error management Add clear signup/login errors for username already taken, email already used, wrong password, failed login, and network errors. Add upload and post creation error messages. If upload fails, user should see a retry option. If publishing fails, app should not create ghost posts. Permission errors for camera, photos, location, and music should show clear messages instead of crashing or silently failing. 2. Landing pages / overlay destinations Create or complete a music/sound page where users can see posts using the same song or sound. Create or complete a location page where users can see posts tagged at the same location. Make tagged users open their profile. Make WordBox open the correct poll, Q&A, or reaction page. Each page needs clean back navigation. 3. Smooth post creation flow User should be able to upload media, edit, add overlays, preview, publish, and return to the feed/timeline. User should not get stuck in editing screens. New posts should appear correctly after publishing. Basic delete post option should work for the post owner. 4. Live Photo flow Smooth the Live Photo feature so users can add photos into a video timeline, preview the final Live Photo, pause/play, go back to edit, and publish without freezing or getting stuck. 5. QF logo / watermark playback controls Tap QF logo once to pause video or Live Photo. Tap QF logo again to resume/play. Double tap QF logo to restart the video or Live Photo from the beginning. 6. Basic social actions Delete post. Comment on posts. Message option if already built. Share post using the phone’s native share sheet so users can share to Instagram, TikTok, YouTube, text message, or copy link. I want this handled as a fixed-price, milestone-based sprint. First milestone should be a code/app review and written fix plan. After that, we can move into implementation. Budget is $1,000–$1,500 depending on what can realistically be completed. I am looking for someone experienced with React Native, Firebase, media uploads, social app flows, iOS/TestFlight, and Android/Google Play testing. No full upfront payment.

I’m building Elevyn, a platform designed to help people better understand themselves through connected data, intentional reflection, and AI-generated insights. This is not a social media platform. This is not a productivity app. This is not just another trading journal. Elevyn is an operating system for self-mastery, with trading serving as the first environment where personal growth becomes measurable. Most apps collect data. Elevyn is designed to observe. The goal is to connect information across different areas of a person’s life and uncover meaningful patterns that help them improve their decision-making, habits, discipline, and overall performance. The Vision Users will log information such as: • Sleep • Mood • Daily reflections • Workouts • Morning routines • Trading activity • Goals • Habits • Personal notes Instead of simply displaying this data, Elevyn will analyze relationships between it and surface meaningful insights. Examples include: • “You slept less than 5 hours before 7 of your last 10 losing trades.” • “Your win rate increases after completing your morning routine.” • “You tend to become more impulsive after multiple winning days.” • “Your consistency improves when workouts and journaling happen on the same day.” The long-term vision is an intelligent system that continuously helps users become more self-aware. Current Stage I already have: • Brand identity • Vision and philosophy • User flows • Interactive prototype • Core feature planning • Long-term roadmap I’m now looking for a developer or small team (2-3 people) to build the first production version. What I’m Looking For I’m looking for someone who can think beyond simply building screens. I want someone who can: • Build scalable architecture • Recommend the best technologies • Think through user experience • Ask thoughtful questions • Help solve technical challenges • Build for future AI integrations • Create clean, maintainable code Experience with AI, analytics, mobile applications, and scalable backend systems is a significant advantage. Technology (Open to Recommendations) I’m open to your recommendations, but I’m considering: • Flutter or React Native • Node.js or Python backend • PostgreSQL • Firebase/Supabase • AWS • AI integrations (OpenAI or similar) • Secure authentication and cloud infrastructure Long-Term Vision Trading is only the beginning. The underlying engine should eventually support entrepreneurs, athletes, creators, students, and anyone pursuing mastery in a specific area of life. The core idea remains the same: Help people understand themselves by connecting patterns across their behaviors, decisions, and outcomes. Who I’m Looking For I’m looking for someone who believes in building meaningful products—not just completing tasks. If you’re excited about creating a platform that combines psychology, data, AI, and personal development into something people genuinely use to improve their lives, I’d love to hear from you. Please include examples of similar work, your recommended tech stack, and how you would approach building a scalable MVP that can grow over time.
