Job Description & Responsibilities

We Make Remote Work Remarkable • TopTalent from LatAm

Hello! We are GoFasti, a Talent-as-a-Service. GoFasti bridges the gap between world-class developers and designers from LatAm and first-class companies around the globe.

We need an English-proficient Mid Level Fullstack Engineer, based in LatAm, available to work remotely.

We are looking for someone with exceptional communication and relationship-building skills, who embraces changes while maintaining strong attention to detail. An interested and proactive person, who's constantly learning and improving their skills.

Are you the one we are looking for?

Responsibilities:

  • Build an internal operational hub to capture client requests and manage projects

  • Build a client portal giving clients visibility into estimates, revision requests, and project status without relying on email

  • Build an internal dashboard for owners to monitor team productivity and project management standards

  • Design and develop client intake forms and workflows to replace spreadsheet-based processes

  • Develop desktop and mobile-friendly experiences for field staff connectivity (responsive web first, with native mobile via React Native as the product matures)

  • Own system architecture, design, and scalability decisions for internal tools

  • Build clean, intuitive interfaces and user flows across internal platforms, leveraging modern component libraries and design systems

  • Collaborate initially with an external development group managing the company's database, with the expectation of eventually taking full ownership

  • Contribute to the development roadmap and help leadership prioritize technical work for current and future products

  • Partner directly with leadership to translate business needs into technical solutions

Requirements:

  • Mid-to-senior level full-stack engineering experience

  • Strong background in system architecture, design, and scalability

  • Strong product sense and an eye for clean, usable interfaces

  • Experience shaping customer/user flows, not just building to spec

  • Comfortable working across both desktop and mobile

  • Fluent English (written and spoken)

  • Entrepreneurial mindset — comfortable with ambiguity and working closely with leadership without needing extensive direction

  • Self-starter capable of long-term, high-autonomy ownership of internal systems

It's a plus:

  • Supabase: compatible with the existing setup; quick to pick up for any strong PostgreSQL + Node.js engineer

  • Frontend tooling: Next.js specifically, Tailwind CSS

  • Mobile: React Native (for the future native mobile phase)

  • API: GraphQL

  • Auth & Hosting: Supabase Auth or Auth0; Vercel/Netlify (frontend); Railway/Render/Supabase (backend)

  • CI/CD: GitHub Actions or equivalent

  • Other: familiarity with Lovable.dev a plus

Compensation:

  • The salary range offered for this position varies from (USD) $3,000 - $5,000 per month, depending on seniority and skillset.

  • This is a 30 days trial requiring 40 hours per week.

  • This position is for a full time contract, through a payroll platform.

  • The talent will work remotely allocated at our client.

Here are the steps for this process:

Application review/approval > Screening interview with GoFasti's team > We build and send your profile to our client > Profile review/approval by client > Interview with the client > Hiring and onboarding.

Once you apply for the job, our team will review your resume. If it meets the requirements, we will contact you and move forward in the process.

Note for Candidates Approached Directly:
If you were contacted directly by a member of our team and are interested in this opportunity, please do not apply through this link. Instead, reach out to the person who contacted you to coordinate a meeting.

Thank you!
