What is a Freelance Full Stack Developer job?

A Freelance Full Stack Developer is a self-employed professional who builds both the front-end and back-end of websites or applications. They work with various technologies, including databases, servers, APIs, and client-side interfaces, to create fully functional digital products. Unlike full-time employees, freelancers work on a project basis for multiple clients, offering flexibility in workload and schedule. Their responsibilities often include coding, debugging, deployment, and sometimes design.

What types of projects and clients can Freelance Full Stack Developers typically expect to work with?

Freelance Full Stack Developers often engage with a diverse range of projects, including website and web application development, e-commerce platforms, mobile app backends, and API integrations. Clients can range from startups and small businesses to established companies and entrepreneurs seeking bespoke digital solutions. The variety in clients and project scopes allows developers to constantly expand their skills and work experience, but it also means adapting quickly to new industries and client expectations. Freelancers typically manage their own workflow, communicate directly with clients, and are responsible for project timelines, making this role ideal for self-motivated technology professionals.

What are the key skills and qualifications needed to thrive in the Freelance Full Stack Developer position, and why are they important?

To thrive as a Freelance Full Stack Developer, you need a solid grasp of both front-end and back-end programming languages (such as JavaScript, HTML/CSS, Node.js, Python, or similar) and a strong portfolio showcasing completed projects. Familiarity with frameworks like React or Angular, version control systems like Git, cloud services, and sometimes relevant certifications (such as AWS Certified Developer) are highly valued. Excellent communication, problem-solving abilities, time management, and client relationship skills help set freelancers apart. These competencies are crucial for effectively delivering end-to-end solutions, managing multiple projects, and building a reliable client base.

Job description


Position
Full Stack Developer
Location
Toronto, ON (100% onsite)
Employment Type
New, Full-Time Permanent position
Salary 
$110,000 - $125,000 (depending on experience) plus incentive compensation 
Hamilton ETFs is building a SaaS platform—a suite of applications designed to power every aspect of our business, including sales, marketing, data intelligence, compliance, reporting, and AI-assisted workflows. Purpose-built for the unique needs of a Canadian asset manager, this platform will be the foundation for how we operate and innovate.
Are you a builder who can take a business problem from concept to execution—breaking it down, designing workflows, and delivering well-tested, scalable solutions?
We’re looking for someone with a strong product engineering mindset who thinks beyond code, balancing user experience, security, scalability, and long-term maintainability while moving quickly and building clean architecture.
You’ll help develop a SaaS platform that powers the real-world needs of a Canadian asset manager across sales, marketing, analytics, and compliance. If this sounds like you, we’d love to hear from you!
Hamilton ETFs offers:
  • A competitive compensation package including comprehensive health and wellness benefits;
  • The chance to shape the product architecture from the ground up;
  • Close collaboration with technology leadership on a platform central to the business;
  • We value collaboration, open-mindedness and service focused mindsets;
  • Diverse and inspiring colleagues and approachable leaders;
  • Opportunity to evolve in a growing firm.
Here’s a bit about Hamilton ETFs:
Hamilton ETFs is one of Canada’s fastest growing exchange traded fund (“ETF”) providers. Based in Toronto’s financial district and with ~$17 billion in ETF assets under management, we are seeking a motivated individual to join our entrepreneurial team of experienced and talented professionals.
Here’s what you will do as Full Stack Developer:
The Full Stack Developer builds production-grade software across the front end, back end, APIs, and integrations for a SaaS platform supporting Hamilton ETFs' sales, marketing, analytics, and compliance teams. The platform includes workflow automation, reporting dashboards, communication tools, and emerging AI-assisted capabilities, with HubSpot as the commercial source of truth.
 
  • Build and maintain the core web application across front end and back end.
  • Develop secure, scalable APIs for CRM workflows, campaign activity, call records, email engagement, user permissions, reporting, and client portals.
  • Create modern interfaces for internal teams and external clients.
  • Build workflow tools for campaign management, contact management, task queues, compliance review, reporting, and operational dashboards.
  • Integrate with third-party systems: HubSpot, email platforms, telephony providers, authentication providers, storage, and analytics tools.
  • Develop AI-assisted features including call summarization, lead scoring, email drafting support, anomaly detection, and natural-language search powered by LLMs and structured data.
  • Work with the Data Platform Engineer to ensure clean data access patterns, performance, security, and auditability.
  • Implement role-based access control, secure authentication, logging, and error handling across the platform's apps.
  • Build reusable components and services that support future products, with clean, testable, documented code.
  • Participate in product planning and help translate business workflows into technical features.
  • Other work or special projects assigned for the overall benefit of Hamilton ETFs.
Here’s what you’ll need to be successful:
  • Strong product engineering mindset with ability to translate business workflows into scalable software systems.
  • Comfortable working in a platform environment where application and data layers are co-designed.
  • Ability to think in terms of systems, user experience, and data flow—not just features.
  • Strong collaboration with data and platform engineering counterparts as well as other Hamilton team members.

Minimum Education, Experience and Skill
  • Post secondary diploma in computer science, computer engineering or similar degree; Masters degree an asset.
  • 4+ years of full stack development experience.
  • Strong experience with modern front-end frameworks (React preferred, or Next.js/Vue).
  • Strong back-end experience in one or more modern languages (Node.js or Python preferred).
  • Experience building REST or GraphQL APIs and service-based architectures and working with relational databases (PostgreSQL preferred).
  • Working knowledge of authentication, authorization, role-based permissions, and secure application design.
  • Hands-on experience building SaaS, CRM, workflow, analytics, or dashboard-heavy applications as well as APIs and data models for multi-tenant SaaS applications.
  • Comfortable with Git, CI/CD, cloud hosting, testing, and production deployment.
  • Strong problem-solving skills and the ability to work independently in a small team.
Preferred Education, Experience and Skills
  • LLM integrations using Anthropic, OpenAI, Azure OpenAI, local models, or similar.
  • Agentic workflows, prompt orchestration, RAG, embeddings, vector search, or AI automation.
  • Telephony platforms such as Twilio, Plivo, or similar, and voice recording or transcription pipelines.
  • Email systems, Microsoft 365, Google Workspace, SMTP, webhooks, or marketing automation.
  • HubSpot or comparable CRM integration.
  • Financial services, asset management, wealth management, or regulated products.
  • Observability, logging, monitoring, background jobs, queues, and event-driven systems.
  • Docker, Kubernetes, serverless, or cloud-native deployment.
  • Security practices: SOC 2 readiness, audit logs, encryption, least-privilege access, and secure SDLC.
