Senior Full-Stack/Software Developer at Factored in Colombia, Colombia

Fully remote | Complete engagement job

Founded in Palo Alto by Dr. Andrew Ng and Israel Niezen, Factored helps U.S. companies build and scale world-class AI, ML, and Data teams, powered by the top 1% of LATAM talent, with a defining purpose: To empower brilliant humans, unleash their potential, and amplify their impact in the world.

At Factored, you’ll be part of a community that values learning, ownership, and authenticity, where your growth is personal and your ideas matter. We’re transparent, curious, and collaborative. We strive for excellence, celebrate diversity, encourage curiosity, and build an environment where you can truly thrive.

As a Senior Software Developer in Business Transformation & Intelligence (BTI), you'll design a clean, scalable architecture for our core platform, the shared software foundation that enables internal teams to ship and maintain their own tools without duplicating effort or re-buying capabilities. You'll work closely with internal departments in a high-ownership, foundational role, building real, in-house software that turns everyone's innovation and creativity into sustainable impact.

---

Functional Responsibilities:

• High Autonomy / High Impact: This is the first purely software-focused position in BTI. You will have significant influence over the engineering culture and technical trajectory of the department.
• Foundation & Architecture: Architect a modular and maintainable full-stack application that serves as the "Factored OS" and sets the engineering standards (testing, documentation, code style) for all future BTI software projects.
• Technical Strategy & Selection: Lead the evaluation and selection of the programming languages, frameworks, and infrastructure components (e.g., databases, hosting) that will form the backbone of the Factored OS, ensuring they align with BTI's goals for performance, security, and developer productivity.
• Technical Mentorship: Directly mentor and pair with a full-time junior engineer on the team, reviewing code, setting technical direction on day-to-day work, and building their ability to independently own well-scoped pieces of the platform.
• Security & Access Control: Design and implement a granular Role-Based Access Control (RBAC) system to ensure that sensitive engineer and candidate data is only accessible to authorized personnel based on their specific functional responsibilities within Factored.
• Documentation & Onboarding: Own and maintain architecture, tech stack, and infrastructure documentation, and build a clear onboarding path (dev environment setup, conventions, runbooks) so new contributors can ramp up quickly.
• CI/CD & Guardrails: Build and maintain CI/CD pipelines with automated testing, linting, and deployment guardrails that enforce quality bars for anyone contributing to the platform.
• Remote & Agile: We operate in a fast-paced, remote-first environment where "shipping to learn" is valued over perfect, delayed specifications.
• Operational Integration: Design and implement bi-directional API integrations with Greenhouse (ATS), HiBob (HRIS), and Jira
• Product Discovery & Shaping: Partner with a Product Manager to translate vague business needs into technical specifications, helping "discover" the product through rapid prototyping and iteration.
• Performance & Scale: Develop a high-performance search and discovery engine for the talent pool (Engineer 360) that remains responsive and accurate as the volume of engineers and data points scales.

Qualifications:

• Senior Engineer (8+ Years): Proven track record of building, deploying, and maintaining full-stack, scalable applications and their underlying infrastructure.
• Startup-Native Mindset: Experience in early-stage environments where you had to build from "zero to one" rather than just maintaining features in a large, pre-existing corporate codebase.
• Leadership: Experience mentoring or directly supervising a junior/mid-level engineer's day-to-day work (not just informal advice).
• Security Fundamentals: Practical experience building modern authentication and authorization patterns (e.g., OAuth2, JWT, RBAC) and experience building applications that handle sensitive PII (Personally Identifiable Information) securely.
• Strong data foundations: Deep understanding of both SQL and NoSQL database architectures, with the ability to justify specific choices based on consistency, latency, and scalability trade-offs.
• System Design: Expertise in designing modular architectures that support future growth without becoming "spaghetti code."
• Modern backend framework proficiency (Node.js/TypeScript, Python/FastAPI, or equivalent) with REST API design
• Modern frontend framework (React/Next.js or equivalent) with component-driven architecture
• Authentication & authorization — OAuth2, JWT, and production RBAC implementation
• Cloud hosting & deployment (AWS/GCP/Azure) with CI/CD pipelines
• Event-driven architectures (queues, pub/sub, webhooks at scale)

Skills & Abilities:

• Architectural Decision Making: The ability to evaluate third-party pay-to-use tools vs. custom-built solutions and select a tech stack that balances price and speed-to-market with long-term maintainability.
• High-Stakes Communication: Ability to translate complex technical plans into clear roadmaps for non-technical stakeholders (PMs, Designers, Sales Leads) and argue for specific technical directions.
• Incremental Delivery: Proficiency in breaking down large, ambiguous product goals into small, prioritized technical tasks that deliver value incrementally.
• Bi-directional Integration: Skill in working with APIs and handling the complexities of state synchronization across multiple external systems.

While it’s not required, it’s an added plus if you also have:

• Greenhouse, HiBob, and Jira API experience (or comparable ATS/HRIS/PM integrations)
• LLM/AI integration via APIs (OpenAI, Anthropic, etc.) for features like summarization and smart matching
• Search engine implementation (Elasticsearch, OpenSearch, Algolia, Meilisearch, or pgvector) for high-performance discovery
• Infrastructure as Code (Terraform, CDK or CF)
• UI/UX sensibility — able to partner deeply with designers and prototype independently
• Performance optimization at scale (caching strategies, query tuning, pagination patterns)

Our Benefits:

• Ownership through equity participation.
• Annual company retreat.
• Education bonus for continuous learning.
• Company-wide winter break.
• Paid time off.
• Optional in-person events and meetups.
• Tailored career roadmaps.
• High-performance culture.

At Factored, we believe that passionate, smart people expect honesty and transparency, as well as the freedom to do the best work of their lives while learning and growing as much as possible. Great people enjoy working with other passionate, smart people, so we believe in hiring right, and are very selective about who joins our team. Once we hire you, we will invest in you and support your career and professional growth in many meaningful ways. We hire people who are supremely intelligent and talented, but we recognize that intelligence is not enough. Perhaps more importantly, we look for those who are also passionate about our mission and are honest, diligent, collaborative, kind to others, and fun to be around. Life is too short to work with people who don’t inspire you.

We are a transparent workplace, where EVERYBODY has a voice in building OUR company, and where learning and growth are available to everyone based on their merits, not just on stamps on their resume. As impressive as some of the stamps on our resumes are, we recognize that human talent and passion exist everywhere, and come from many backgrounds, so stamps matter much less than results. All of us are dedicated doers and are highly energetic, focusing vehemently on execution because we know that the best learning happens by doing. We recognize that we are creating OUR COMPANY TOGETHER, which is not only a high-performing fast-growing business but is changing the way the world perceives the quality of technical talent in Latin America. We are fueled by the great positive impact we are making in the places where we do business and are committed to accelerating careers and investing in hundreds (and hopefully thousands) of highly talented data science engineers and data analysts.

In short, our business is about people, so we hire the best people and invest as much as possible in making them fall in love with their work, their learning, and their mission. When not nerding out on data science, we love to make music together, play sports, play games, dance salsa, cook delicious food, brew the best coffee, throw the best parties, and generally have a great time with each other.
