Senior Full-Stack Engineer

Senior Full-Stack Engineer (React/Node) - Fully Remote (must be located in Costa Rica)

Location: 100% Remote (Costa Rica) 🇨🇷

Schedule: US Pacific Time (PST)

Type: Full-time

About the Role

Are you the kind of engineer who loves building things from the ground up and actually cares about how well they work under the hood?

We are partnering with a fast-growing US startup to find a Senior Software Engineer based in Costa Rica. This isn't just a "ticket-taking" role. We need a tech partner, someone who can design scalable architecture, write beautiful, bulletproof code, and own the cloud environment. If you thrive in fast-paced startup environments and believe that "quality engineering" is a mindset, not just a phase, we want you on our team!

The "In-House" Difference: We are looking for true product builders. We have a strong preference for candidates who have held direct, in-house roles with companies rather than working in a consulting or agency capacity.

What You’ll Do

• Design and architect scalable and reusable software
• Document decisions and designs in a clear way
• Develop software using software engineering best practices
• Thoroughly test individual pieces of code and the system as a whole
• Build and manage the cloud computing environments

Qualifications

• 7+ years of software engineering experience in fast-paced, startup environments. (Note: Must have a strong track record of direct in-house roles; heavy consulting/agency backgrounds are not a fit for this team).
• Experience with all elements of our tech stack:
• PostgreSQL
• GraphQL
• TypeScript
• React
• Express
• Experience with Cloud Services and Architecture (GCP and AWS)
• Ability to work US Pacific Time (PST) hours
• Strong English Proficiency is a must, as you'll be collaborating directly with the US team without translators.

Please only apply if:

• You are currently physically located in Costa Rica.
• Your primary, day-to-day backend ecosystem is Node.js/Express and TypeScript (Profiles primarily focused on .NET, Java, Python, or PHP will not be considered).
• You enjoy owning the cloud infrastructure and writing your own automated tests.
