Full-Stack Developer (Junior) Role

Role Overview

As a Junior Full-Stack Developer, you'll build and iterate on customer-facing features for LeadUp's AI platform, directly impacting user adoption and sales pipelines. Your code will power tools used by thousands of teams, giving you visible business contributions in a remote setup spanning US and Latin America time zones. This role suits rising juniors or seniors ready for production-level coding without years of experience.

Detailed Responsibilities

• Develop responsive front-end interfaces using React for lead dashboards and analytics views.
• Build secure back-end APIs with Node.js to handle AI model inferences and data pipelines.
• Integrate third-party services like Salesforce and HubSpot for seamless data syncing.
• Collaborate on database optimizations using PostgreSQL to support high-volume lead scoring.
• Write unit and integration tests to ensure 99% uptime on core features.
• Participate in code reviews and deploy updates via CI/CD pipelines.
• Assist in troubleshooting production issues and monitoring with tools like Sentry.

Day-to-Day Workflow

Your day starts with a quick async standup in Slack, reviewing overnight metrics from lead conversion experiments. Mornings involve pair-programming sessions on new features, like tweaking a React component for better mobile UX, followed by lunch in your time zone. Afternoons shift to back-end tasks, such as optimizing Node.js endpoints for faster AI queries, with time blocked for learning via internal docs or mentor check-ins.

Expect 4-6 hours of focused coding, interspersed with pull request reviews and bi-weekly demos to the product team. Ends with logging progress in Jira, prepping for the next sprint—flexible to accommodate US/LatAm schedules.

Tools and Technologies

• Front-end: React, TypeScript, Tailwind CSS
• Back-end: Node.js, Express, Python for AI scripts
• Database: PostgreSQL, Redis for caching
• DevOps: Docker, AWS (EC2, Lambda), GitHub Actions
• Collaboration: Slack, Jira, Figma for UI mocks
• AI/ML: TensorFlow.js, OpenAI API integrations

Skills and Requirements

Technical Skills

LeadUp AI expects proficiency in JavaScript/TypeScript and React for front-end, plus Node.js for back-end services. Familiarity with RESTful APIs, SQL databases, and Git is essential; bonus for Docker and basic AWS. No deep ML knowledge needed—focus on integrating pre-built AI models into web apps.

Soft Skills

Strong problem-solving shines in debugging live issues, while clear async communication via Slack keeps remote teams aligned. Teamwork matters in code reviews, and adaptability helps navigate fast sprints across time zones. Initiative, like proposing UX tweaks, sets juniors apart.

Experience Expectations

Prioritize a GitHub portfolio with 2-3 full-stack projects, such as a MERN app or AI chatbot demo—no enterprise experience required. GPA above 3.2 helps but isn't mandatory; personal projects trumping academics. Open to US/LatAm students in CS or related fields, targeting upcoming season interns.

Salary and Benefits

For the upcoming season, expect $25-$35/hour for US-based interns or $2,500-$4,000/month equivalent in Latin America, scaling to $80K-$100K for full-time conversions. Competitive with Bay Area startups but adjusted for remote locations.

• Full remote setup with $1,000 home office stipend.
• $500 annual learning budget for Udemy or conferences.
• Unlimited PTO and wellness days.
• Mentorship from senior devs, with 70% conversion to full-time roles.

Application Timeline

Apply now for upcoming season starts in June-July; process wraps in 2-3 weeks. Peak applications hit in April-May, so early birds get priority. Rolling admissions favor quick responders.

Screening Methods

Lever ATS scans for keywords like "React", "Node.js", and "full-stack projects". Portfolio must include live demos; cover letters referencing LeadUp Predict score high. No LeetCode upfront—focus on practical builds.

Interview Preparation

Example Interview Questions

• "Walk us through building a React component that fetches and displays AI-generated leads from a Node API."
• "How would you optimize a slow PostgreSQL query for 10K daily lead scores?"
• "Describe a project where you integrated a third-party API—challenges and fixes?"
• "Explain async/await vs promises in a real-world full-stack scenario."

How to Answer

Use the STAR method: Situation, Task, Action, Result. For technicals, think aloud—sketch code on Excalidraw, explain trade-offs like state management in React. Practice with a mock API to demo live.

Back answers with your portfolio: "In my lead tracker app, I used Redux for state, reducing re-renders by 40%—here's the GitHub."

What Recruiters Evaluate

Core criteria: clean, functional code over perfection; ability to learn fast; cultural fit via ownership stories. They value LatAm time zone flexibility and enthusiasm for AI sales tools. Metrics like assignment completion time (under 4 hours) signal productivity.

How to Get Selected

Practical Tips

• Tailor your resume with LeadUp-specific keywords from their job post.
• Build a mini-project mimicking LeadUp Predict—deploy to Vercel/Netlify.

How to Stand Out

Submit a customized take-home with LeadUp integrations, like HubSpot API hooks. Network on LinkedIn—comment on company posts, DM alums for coffee chats. Contribute to open-source AI repos; mention in app. For LatAm candidates, highlight bilingual skills for cross-region features.
