Top 3 Reasons To Join Us Profitable startup from Year 1! High pay, MacBook Pro, $1000 annual development Work with top talent on product changing industry The Job About the Opportunity We are looking for an elite Internal Tools Builder to act as the engine behind our company's operations. As we evolve into a full-funnel marketing platform serving over 600k+ verified users, our internal operations, ERP, and tooling need to scale just as fast. In this role, you will work directly with company leadership to identify operational bottlenecks and build custom internal systems from the ground up. You will not be handed a perfect ticket; you will be handed a business problem. We need a highly autonomous Fullstack Engineer with a relentless "builder mindset" who can lead the topic, architect the system, and collaborate with other engineers to get it across the finish line. What You Will Do You will not just "write code." You will own internal products end-to-end. Your core challenges will include: Build the Engine: Architect and build robust internal tools, ERP modules, and operational systems across the entire stack (Database -> API -> UI) to make our internal teams wildly efficient. Direct Collaboration with Leadership: You will work directly with leadership/the boss. You must be comfortable hopping on a call, translating a vague business problem into a technical roadmap, and executing it. Lead the Topic: You are the technical owner. You will drive the architecture, make the hard technical trade-offs, and push back when necessary to ensure we are building the right thing. Mentorship & Collaboration: You won't be doing it entirely alone. You will pair with and mentor a junior engineer—delegating tasks effectively, doing code reviews, and helping them level up their full-stack skills. Performance & Architecture: Balance speed with stability. Know when an internal tool just needs a quick MVP to save the team 10 hours a week, and when a system needs to be highly scalable to handle massive data throughput. Your Skills and Experience What You Need to Be Successful We hire for mindset first, technology second. 1. The Builder Mindset Idea to Reality: You thrive on ambiguity. You can take a vague request ("We are losing track of customer billing edge-cases") and independently architect the database, build the API, and craft the UI to solve it. Internal Systems Expertise: You have experience building internal tools, ERPs, CRMs, or admin dashboards. You know how to stitch together third-party APIs, webhooks, and internal databases. 2. Engineering Skills Deep Experience (5+ Years): You have a strong foundation in building complex, production-ready web applications. Fullstack Fluency: You are completely comfortable jumping between backend logic (API design, complex SQL/Database modeling) and the frontend (React, state management) without skipping a beat. 3. Communication & Leadership Exceptional Communicator: Because you work directly with leadership, your written and spoken English must be excellent. You can explain complex technical trade-offs to non-technical stakeholders clearly and confidently. Force Multiplier: You have the patience and communication skills to mentor a junior engineer, breaking down complex architectures into actionable tasks for them. Why You'll Love Working Here Impact: The tools you build will instantly become the backbone of how our company operates daily. Culture: We are a lean, fast-growing team that values Good Design, Trust, and Empowerment. We invest in our people and give them the autonomy to do their best work. Perks: Highly competitive salary + 13th-month bonus. Stock options for high contributors. Professional development package of up to $1,000/year. Modern office with top-notch equipment (MacBook Pro). Comprehensive healthcare package (Annual health check, Premium Health Insurance). Flexible working hours with a standard 5-day workweek
