The Opportunity

Join a fast-growing AI marketing agency at a pivotal moment. We're not just using AI—we're building proprietary platforms that transform how brands approach marketing. As our Principal/Lead Engineer, you'll architect and build the technical foundation that powers innovative AI-driven marketing solutions for global clients.

This isn't a typical engineering role. You'll have the unique opportunity to:

• Shape the technical vision of a growing AI company from the earliest stages

• Work with cutting-edge AI technologies (GraphRAG, LLMs, generative AI pipelines) in production

• Balance hands-on development (65% coding) with strategic architecture decisions (35%)

• Partner directly with enterprise clients—including Fortune 500 companies—as their technical counterpart

• Build and mentor a world-class engineering team as we scale

What You'll Do

Strategic Architecture (35% of time)

• Design scalable, secure cloud architectures for AI-powered marketing platforms across AWS/Azure/GCP

• Partner with enterprise clients as the technical counterpart to their Solution Architects and IT leadership teams

• Make critical technology decisions, balancing rapid MVP delivery with long-term scalability

• Evaluate AI tools and infrastructure—build vs. buy decisions for AI models, commercial APIs vs. open-source solutions

• Plan for compliance and security—prepare for ISO 27001, GDPR, and CCPA certifications

• Own the technical roadmap aligned with business objectives and market needs

Hands-On Development & Technical Leadership (65% of time)

• Build core platform components using Python (FastAPI/Flask), designing and implementing production-ready APIs

• Architect end-to-end data pipelines—from ingestion through processing to AI model integration

• Lead infrastructure setup—establish CI/CD pipelines, infrastructure-as-code (Terraform), containerization (Docker/Kubernetes)

• Develop AI/ML solutions—implement GraphRAG pipelines, RAG architectures, and integrate LLM APIs into production systems

• Code review and mentor engineers while maintaining high code quality standards

• Drive engineering excellence—establish development workflows, testing practices, and modern Agile/Lean methodologies

Team Building & Culture

• Lead by example through hands-on contributions and code reviews

• Establish engineering best practices and quality standards that scale

• Build and mentor the engineering team as we grow

What We're Looking For

Must-Have Experience

• 7+ years of software engineering experience with increasing technical leadership

• Fluent English & Spanish (written and spoken)—you'll engage daily in complex technical discussions with international clients and stakeholders

• Strong Python expertise with modern frameworks (FastAPI, Flask) and API design (REST, GraphQL)

• Production cloud experience designing and deploying scalable systems on AWS, Azure, or GCP

• DevOps & Infrastructure mastery—Docker, Kubernetes, CI/CD, infrastructure-as-code (Terraform)

• Data architecture experience—designing data pipelines, ETL processes, and working with both SQL and NoSQL databases

• Track record of building 0-to-1 products or leading technical initiatives in startup/scale-up environments

Highly Desired (What Makes You Stand Out)

• AI/ML production experience—especially with LLMs, RAG architectures, GraphRAG, or generative AI pipelines

• Experience as a technical liaison to enterprise clients or as Solution Architect on large-scale projects

• Vector databases (FAISS, Weaviate, Qdrant) or graph databases (Neo4j) experience

• Background in marketing tech, adtech, or SaaS platforms

• Security & compliance knowledge—ISO 27001, SOC 2, GDPR, or similar frameworks

• Open-source contributions or technical writing/speaking experience

Personal Attributes

• Entrepreneurial mindset—comfortable with ambiguity and excited about building from scratch

• Hands-on builder who can balance strategic thinking with getting into the code

• Excellent communicator—able to explain complex technical concepts to both technical and non-technical audiences

• Quality-driven with strong opinions about best practices but pragmatic about trade-offs

• Natural mentor who enjoys helping others grow technically

• Curious about AI and passionate about its practical applications in business
