Job Summary: We are looking for a Senior Backend Developer with strong experience in Python and Django to design, build, and scale core services while making architectural decisions in an agile, high-velocity environment. Key Highlights: 1. Real participation in architecture and product decisions 2. Asynchronous work environment with a results-oriented culture 3. Opportunity to grow within a SaaS platform expanding across Latin America We are a leading cloud-based SaaS platform for audit management in Latin America. We help internal and external auditors structure, implement, and document their work in real time, complying with international standards such as ISA, NOGAI 2024, and NIGC1\. We are experiencing rapid growth and seeking someone who wants to build software that truly matters. **The Role** We are looking for a **Senior Backend Developer** with strong experience in Python and the Django ecosystem to join our product team. You will be responsible for designing, building, and scaling the core services of our platform, ensuring performance, security, and quality in every line of code. This is not a maintenance role: here, you will make architectural decisions, have a voice in the technical roadmap, and collaborate directly with the product team in an agile, high-velocity environment. **Your Responsibilities** Design and implement robust, well-documented REST APIs using Django / Django REST Framework Model and optimize PostgreSQL schemas for complex domains (multi\-tenant, audits, approval workflows) Implement and maintain asynchronous tasks and job queues using Celery \+ Redis Write unit and integration tests as a natural part of development—not as an afterthought Collaborate on architectural decisions, code reviews, and defining the team’s technical standards Actively participate in the full cycle: refinement, development, QA, and deployment **What We Require (Non-Negotiables):** **5\+ years** of professional backend development experience in fields such as systems engineering, computer science, or related disciplines Deep expertise in **Python** and **Django** (including ORM, signals, middleware, custom management commands) Solid experience with **Django REST Framework** and scalable API design Advanced proficiency in **PostgreSQL**: indexing, complex queries, optimization, production migrations Real-world experience with **Celery** \+ **Redis** in production environments (not just tutorials) Strong culture of **automated testing**: unit, integration, mocking—with pytest or equivalent Clear understanding of SaaS application architecture: multi\-tenancy, security, separation of concerns Ability to read, write, and communicate effectively in technical English (documentation, PRs, issues) **Bonus Points (Desirable)** Knowledge of **AWS**: EC2, RDS, S3, SQS, ECS, or Lambda Experience with **Next.js / React**—not the focus of this role, but versatility is valued Familiarity with **Docker** and containerized deployments Experience with applications involving complex workflows (approvals, states, audits, compliance) Knowledge of security standards for financial or regulated applications **Your Profile** You think fast, execute fast, and iterate quickly when you make mistakes. You possess your own technical judgment and aren’t afraid to defend your decisions with sound reasoning. Technical debt bothers you as much as it does us. You enjoy teamwork but are fully autonomous when needed. You’ve been doing this for over 5 years—and it shows: in your code, in your PRs, in how you articulate trade\-offs. **What We Offer** Hybrid work from Colombia Birthday day off Small, focused, and technically discerning engineering team Real participation in architecture and product decisions Asynchronous work environment with a results-oriented culture Opportunity to grow within a SaaS platform expanding across Latin America Highly competitive salary for the right candidate.
