As we continue to grow our teams, we urge you to be cautious of fraudulent job postings or recruitment activities that misuse our company name and information. Please protect your personal information during any recruitment process. While Monks may contact potential candidates via LinkedIn, all applications must be submitted through our official website (monks.com/careers).

We’re looking for a Senior Full Stack Engineer to join our team. Whether you’re ready to embed with an established squad or help bootstrap a brand-new one, this is an opportunity to build impactful features across the stack with modern tools and a smart, collaborative team. You’ll report to an Engineering Manager and work on real, high-impact initiatives.

Responsibilities:

Own end-to-end feature delivery—from UI/UX to API and database design.
Build and maintain scalable React interfaces
Architect and implement APIs using NestJS and Postgres
Manage integrations with external services using internal credential/token management systems
Design and implement secure OAuth 2.0 flows and SSO (Google, Microsoft, etc.)
Contribute to and maintain our Docker/Kubernetes/Helm-based infrastructure
Collaborate with designers, product managers, and engineers across the organization
Write clean, maintainable, and well-documented code across the stack

About You

The essentials:

5+ years of full stack development experience
Strong proficiency with TypeScript, React, NestJS, and Postgres
Comfortable shipping across the entire stack—UI to DB.
Experience with monorepo tooling (pnpm, turborepo, nx)
Solid understanding of API authentication, credential management, and secure integrations with third-party services
In-depth knowledge of OAuth 2.0, including implementation of valid auth flows and SSO
Experience working with Docker, Kubernetes, and Helm in production environments
Familiarity with domain-driven design or clean architecture patterns

Not a must, but a plus:

Experience with infrastructure as code (we use Terraform)
Prior work in high-compliance environments (HIPAA, SOC2, etc.)
Experience bootstrapping new squads or systems from scratch.
AI/ML familiarity—especially implementing tools like LangChain or working with embeddings and RAG pipelines

Location Requirement:

This is a remote role, but applicants must be based in Brazil and legally eligible to work in the country.
