About Just Badge Worldwide

Just Badge Worldwide is building ELITE—the global skills verification platform that transforms how professionals prove capability through real-time behavioral data, not resumes. We've proven the concept, validated our acquisition model, and we're finishing the final 20% of ecosystem development. We're pre-revenue, founder-funded, and preparing for public launch. Join now to help us build the foundation, onboard our first subscribers, and position ourselves for scale.

The Role

This is a high-impact technical role for a highly-experienced full-stack developer who thrives on shipping fast, solving complex problems, and leveraging AI development tools to accelerate execution. You'll build the core features of ELITE—a professional social network with behavioral skill tracking, community infrastructure, session booking marketplace, and gamification systems;all while maintaining clean architecture and cost-conscious technical decisions.

You'll work in a fast-paced, AI-assisted development environment where we use tools like Cursor, GitHub Copilot, and traditional software development tools to move quickly without sacrificing quality. This role requires both technical depth and startup pragmatism: knowing when to build from scratch, when to fork open-source projects, and when to integrate third-party solutions.

What Success Looks Like

• Month 1-3: Ship 3-5 high-priority features (social network core, authentication, profiles, activity feeds). Integrate with existing codebase and establish development workflows.

• Month 4-6: Complete session booking marketplace, payment processing, and email automation. Launch beta with core feature set ready for user testing.

• Month 7-9: Build gamification systems, behavioral tracking integrations, and AI-powered skill categorization. Optimize performance, cost, and user experience based on beta feedback.

Development Methodology

We work in 6-week sprints with a focus on shipping MVPs quickly:

• MoSCoW prioritization: Must Have, Should Have, Could Have, Won't Have

• Minimum Viable Feature (MVF) approach: Ship core functionality first, iterate based on feedback

• AI-assisted development: Use AI tools for scaffolding, testing, and documentation

• Weekly progress reviews: Feature prioritization and risk mitigation planning

• 12-20 week timeline to production beta: Fast-paced execution with clear milestones

&

&

Mindset Values

• Ship fast, iterate faster: You prioritize delivering working features over perfect architecture, then refine based on real user feedback.

• AI-native developer: You embrace AI tools as productivity multipliers and know how to use them effectively.

• Problem solver: You find creative solutions to technical challenges, especially when balancing cost, performance, and speed.

• Self-directed: You take ownership of features end-to-end and don't need hand-holding.

• User-focused: You care about building intuitive, performant experiences that users love.

• Mission-aligned: You believe in the vision of verified professional capability and understand how your code enables that future.

&

Compensation Equity

• Competitive base salary upon funding: $120K-$160K (depending on experience and location)

• Equity: 0.25%-0.75% in stock options (4-year vesting with 1-year cliff)

• Performance bonus: Tied to feature delivery milestones and platform launch success

Start Before Funding (Preferred Candidates)

For exceptional developers who want to start contributing immediately:

• Part-time or full-time on an equity-only basis with vesting beginning after the trial period

• Equity grant remains the same (0.25%-0.75%)&

• Contractor to start and transition to full salary + benefits package upon funding close + signing bonus (backpay)

• Early vesting credit for pre-funding contributions

This option is ideal for developers who believe in the mission and want to shape the platform from the earliest stage while accelerating their equity position.

Timeline

This role will be hired upon funding close, anticipated in the coming weeks. However, we're open to bringing on the right candidate earlier on an equity-only basis to begin vesting immediately.

Why This Role Matters

You're not just writing code—you're building the infrastructure that enables professionals to prove their capabilities and unlock opportunities based on verified skills, not resumes. Every feature you ship helps people connect, grow, and earn in ways that weren't possible before.

This is a founding engineering role where your technical decisions shape the platform's scalability, user experience, and long-term success. If you're a builder who thrives on fast execution, AI-assisted development, and mission-driven work, this is your opportunity to create something that matters.
