3Pillar is an AI transformation partner on a mission to help enterprises build the AI-native products and intelligent agents that will define the next era of business. With teams across North America, Europe, Latin America, and Asia, we work with the most ambitious companies in financial services, healthcare, media, and technology — helping them move faster, modernize boldly, and compete on their own terms. Our HelixAI platform and Helix Pods delivery model put our engineers at the center of real agentic transformation — doing work that is open, portable, and built to last. We are building the future of enterprise AI.

Step into the architect's seat on some of the most consequential product development work at 3Pillar! We invite you to join our team and set the technical direction for a platform modernization.

At 3Pillar, our focus is on crafting cutting-edge technologies that revolutionize industries.

Responsibilities:

• Own the end-to-end architecture, from target-state design and decision records to a successful launch, balancing performance, scalability, security, testability, and cost.
• Lead the modernization of legacy platforms into the new architecture, defining the migration boundary, cutover strategy, and parity checks so delivery continues throughout.
• Set and uphold engineering standards across the team: design patterns, shared components, code review practice, test strategy, and quality gates that protect critical customer behavior.

Qualifications:

• 13+ years of software engineering experience, including at least 4 years as a solution or technical architect on systems of medium-to-large scope and complexity.
• Full Stack Architect with experience in Angular 20, Node, Express, Postgresql.
• Expert-level design proficiency following UML / C4 / ArchiMate, with a record of architecture decisions that held up in production.
• Deep expertise across the stack: Angular on the front end and Node.js with Express on the back end, with the judgment to guide others and not only build.
• Mastery of relational databases and SQL (PostgreSQL), including multi-tenant data isolation with row-level security, migrations, and performance tuning.
• Experience with cloud-native delivery: AWS, containers, Kubernetes and Helm, CI/CD pipelines, and release and recovery practice (smoke tests, rollback, restore).
• Demonstrated leadership of Agile teams and clear communication with executives and clients.
• Proficiency in the English language.

At 3Pillar, we offer a world of opportunity:

• Imagine a flexible work environment – whether it's the office, your home, or a blend of both. From interviews to onboarding, we embody a remote-first approach.
• You will be part of a global team, learning from top talent around the world and across cultures, speaking English everyday. Our global workforce enables our team to leverage global resources to accomplish our work in efficient and effective teams.
• We’re big on your well-being – as a company, we spend a whole trimester in our annual cycle focused on wellbeing.

• Our professional services model enables us to accelerate career growth and development opportunities - across projects, offerings, and industries.
• We are an equal opportunity employer. It goes without saying that we live by values like Intrinsic Dignity and Open Collaboration to create cutting-edge technology AND reinforce our commitment to diversity - globally and locally.
