Senior Full Stack Developer

Averian is an AI and custom solutions company building real-world systems deployed in mission-critical, production environments. We design and deliver advanced platforms and solutions that help enterprises build cutting-edge applications that improve quality, reliability, and operational efficiency. Our work goes beyond prototypes. Our software is used in live environments where accuracy, stability, and performance truly matter.

Working with global technology partners across North America and Europe, we operate as a focused, senior team where engineers and product leaders have meaningful ownership, direct access to customers, and a strong influence on technical and architectural decisions.

If you enjoy solving complex technical problems, working closely with real customers, and seeing your work deployed in production, we want to hear from you!

Averian offers a high-impact environment where your contributions genuinely matter.

We are seeking an experienced and self-driven Senior Full Stack Developer to lead the technical implementation of a cutting-edge platform.

The ideal candidate is independent, hands-on, and technically versatile, capable of driving full-cycle system implementation from architecture and design to deployment. You will be responsible for architecting and building solutions from MVPs to fully featured products, from the ground up, ensuring robust foundations for scale and AI integration. You will work across the full stack (e.g. React/Next.js/Node.js, .NET, Postgre

SQL, Mongo

DB to name a few) and ensure platforms are secure and perform to specification.

• Design and build the full stack of the platform using frameworks such as (examples) React.js / Next.js (Frontend) and .Net or Node.js, Postgre
  
  SQL (Backend).
• Architect complex data models to handle multi-entity hierarchical structures and historical data.
• Implement secure, multi-tenant architecture on cloud (AWS/Azure) with a focus on enterprise security standards (Encryption, Access Control, Audit Logs, and Logic Isolation).
• Develop modular “Logic Containers” for complex business calculations and validation rules.

• Translate mock-ups, designs and requirements into responsive, interactive user interfaces (Data grids, Complex Data Visualizers).
• Build high performance service oriented back-end solutions with horizontal scalability in mind.
• Ensure codebases are “AI-Ready” by maintaining strict data structures that will support future AI agent integration.
• Participate in architecture reviews, code reviews, and creation of technical documentation.
• Work directly with the Product Owner and leadership to refine requirements and prioritize features.
• Mentor junior developers and foster adherence to technical standards and best practices.

• 7+ years of professional experience in software development, including system design and backend architecture.
• Strong expertise in Modern Frontend Frameworks (React, Next.js, Type Script) and building complex, interactive UIs.
• Experience building high performance back-ends using .Net core or Node.js.
• Strong understanding of Relational Databases (i.e. Postgre
  
  SQL) and modeling complex, hierarchical data structures.
• Experience with AWS (ECS, VPC, S3) and/or Azure, and secure cloud architecture.
• Experience building SOC 2 compliant or high-security applications (handling sensitive PII or business-critical data) is highly preferred.
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field.
• Ability to independently plan, execute and deliver custom projects from requirements to deployment.

• Experience with “Infrastructure as Code” (Terraform/CDK).
• Familiarity with data visualization libraries (for charts and tree diagrams).
• Experience preparing systems for future AI/LLM integration.
• Experience with fine-tuning LLMs or building RAG pipelines is a plus.

This role is 100% work from office. It is based in Ottawa, Ontario, Canada. Relocation of candidates will not be considered or provided.

• Opportunity to lead and shape the engineering vision of next-gen solutions.
• Collaborative and fast-paced work environment.
• A chance to work on cutting-edge technology and make a real business impact.
• A chance to work with customers on the cutting edge of technology development and adoption.

If you are passionate about building robust, scalable platforms and have the expertise to deliver high-quality software, we’d love to hear from you!
