About Human Agency
We're scaling rapidly and have a growing pipeline of opportunities that demand exceptional talent across disciplines. Our mission is to bring on individuals, from creative producers to technical experts to entrepreneurial leaders, who can help us realize this next chapter of growth.
We are a company of doers. Leaders roll up their sleeves, teams work flat, and everyone contributes to what ships. Titles don't insulate us from feedback or basics. We invite critique, learn quickly, and keep raising the bar. The best ideas win here, no matter where they come from, because clients trust us to deliver the strongest outcomes every time.
Our clients' missions, products, and bottom lines are sacred. We immerse ourselves in their world, becoming stewards of their goals and partners in solving big problems. Every product, strategy, or asset we create must be both beautiful and functional; practical, usable, and designed for real-world impact.
Humans are our most valuable resource, and we only grow by hiring people who push us forward. Across strategy, engineering, design, data, and operations, we seek out teammates who raise the bar and make us better. Always hire up, never down.
We partner with organizations of all sizes to explore, design, and implement AI strategies that are secure, scalable, and human-centered. We believe AI should amplify human potential, not replace it and we build with that conviction in every engagement. From advisory and tooling to implementation and education, we meet clients where they are at and help them integrate AI in ways that align with their mission and values. Our goal is to empower teams to work smarter, move faster, and unlock new possibilities through thoughtful, responsible innovation.
And through it all, we lead with purpose, love, and adventure. We do meaningful work with people we care about, and we make the ride an adventure worth taking. Because at Human Agency, who we are and how we work are one and the same.
The Opportunity
At Human Agency, we are shaping the future by combining cutting-edge AI solutions with intuitive software development. We specialize in building scalable and secure SaaS applications that empower enterprise clients to solve complex problems efficiently. As part of our team, you'll work on high-impact projects at the intersection of AI, machine learning, and secure software engineering.
We're seeking a Senior Full-Stack Engineer to join our growing team. In this role, you'll lead development initiatives, contribute to our SaaS products, and tackle exciting challenges in backend architecture, frontend design, and AI/ML integrations with a particular focus on generative AI technologies.
Responsibilities
SaaS Application Development
  • Detection:
    • Develop backend algorithms to process articles, chunk content, and integrate with LLMs for predictive text generation.
    • Build APIs and services to manage and scale the application's content workflow.
  • Protection:
    • Create secure PDF upload workflows with encryption to ensure compatibility with Adobe Acrobat.
    • Integrate authentication mechanisms like Okta for enterprise customer admin management.
    • Enable data recovery, auditing capabilities, and enterprise-grade administrative tools.
AI/ML and Algorithm Development
  • Collaborate with AI/ML teams to operationalize models such as OCR (Optical Character Recognition) and generative AI-based solutions (e.g., GPT models).
  • Implement RAG (Retrieval-Augmented Generation) use cases using vector databases and data embedding techniques to enhance application functionality.
  • Design workflows for large-scale data processing that enable efficient AI integrations and create dynamic AI-first features, such as custom GPTs tailored to enterprise needs.
DevOps & Operationalization
  • Establish CI/CD pipelines and formal release structures for software delivery.
  • Conduct security evaluations to identify vulnerabilities and optimize performance across AI-driven SaaS applications.
  • Manage infrastructure and workflows for custom AI solutions, including tools like Snowflake and LangChain.
Future-Focused Development
  • Build integrations and proof-of-concept applications leveraging company-specific datasets and AI technologies.
  • Evaluate and implement tools for classification, indexing, and secure data management that incorporate the latest in generative AI advancements.
  • Support the development of enterprise-grade AI solutions, including internal AI models and custom LLMs.
Requirements
Core Technical Skills
  • Proficiency in Python and Ruby on Rails, with significant backend experience.
  • Experience in designing secure systems, including encryption workflows and document protection mechanisms.
  • Hands-on expertise in integrating generative AI tools, such as OpenAI APIs, LangChain, or Hugging Face frameworks, into SaaS applications.
  • Strong knowledge of RAG techniques, vector databases (e.g. Pinecone, Weaviate), and embedding pipelines.
  • Ability to operationalize AI/ML models and build workflows for enterprise clients.
  • Frontend development experience in modern frameworks (e.g, React, Vue), with the ability to assess and recommend appropriate tech stacks.
Nice-to-Have Skills
  • Computer vision and OCR expertise, especially for processing and indexing complex document workflows.
  • Experience with authentication systems (e.g., Okta) and enterprise administrative tools.
  • Experience in DevOps, CI/CD pipelines, and secure release management.
  • Background in security evaluations, vulnerability assessments, and tool integrations.
Other Requirements
  • Strong testing background with experience in automated and manual testing.
  • Ability to manage data recovery, audits, and compliance workflows.
  • Strong problem-solving and analytical skills, with attention to detail in complex environments.
  • Excellent communication skills and the ability to work collaboratively across teams.
Why Join Us?
  • Be part of a cutting-edge team solving complex problems in AI and SaaS development.
  • Work on impactful projects with enterprise clients and cutting-edge technologies.
  • Grow your career in a collaborative, innovative, and supportive environment.

If you're excited about working on secure, scalable systems while integrating advanced AI and ML capabilities, we'd love to hear from you.
Equal Opportunity Commitment
