Job Summary: We are seeking a Senior Backend Developer with strong experience in Python and Django to join an agile product team, designing and scaling core services of a leading SaaS platform for audit management. Key Highlights: 1. You will make architectural decisions and have a voice in the technical roadmap. 2. Collaborate on architectural decisions and definition of technical standards. 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 seek someone who wants to build software that truly matters. **The Role** We are looking for a **Senior Backend Developer** with solid 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 position: here, you will make architectural decisions, have a voice in the technical roadmap, and work directly with the product team in an agile, high-velocity environment. **What You’ll Do** 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 with Celery \+ Redis Write unit and integration tests as a natural part of development—not as an afterthought Collaborate on architectural decisions, code reviews, and definition of the team’s technical standards Actively participate in the full cycle: refinement, development, QA, and deployment **What We Need (Non-Negotiable Requirements):** **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 design of scalable APIs Advanced proficiency with **PostgreSQL**: indexes, complex queries, optimization, production migrations Real-world experience with **Celery** \+ **Redis** in production environments (not just tutorials) Culture of **automated testing**: unit, integration, mocking — using pytest or equivalent Clear understanding of SaaS application architecture: multi\-tenancy, security, separation of concerns Ability to read, write, and communicate 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 featuring 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 independent technical judgment and aren’t afraid to defend your decisions with sound reasoning. Technical debt bothers you as much as it bothers 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, and in how you communicate trade\-offs. **What We Offer** Hybrid work from Colombia Birthday day off Small, focused, and technically discerning engineering team Real participation in architectural 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.
