Seasonal Full Stack Developer information

Are full-stack devs still in demand?

Full-stack developers remain in high demand due to their versatility in handling both front-end and back-end development, especially with skills in frameworks like React, Angular, and Node.js. Companies value their ability to work across the entire technology stack, making them essential in many software development projects and startups.

What is a Seasonal Full Stack Developer?

A Seasonal Full Stack Developer is a software engineer hired on a temporary or contract basis, typically during peak periods, to work on both front-end and back-end development tasks. They are proficient in a range of programming languages and frameworks, allowing them to handle the complete development process of web applications. These roles are often found in companies with cyclical workloads or special projects that require additional resources for a limited time. Seasonal Full Stack Developers collaborate with other team members to ensure that applications are built efficiently and meet the company's needs during busy seasons.

What is a seasoned full stack developer?

A seasoned full stack developer is an experienced software professional skilled in both front-end and back-end development, often with several years of work in technologies like JavaScript, HTML, CSS, and server-side languages. They are proficient in frameworks, version control, and deployment processes, and can handle all aspects of software development lifecycle. Such developers are valued for their versatility, problem-solving abilities, and ability to work across different parts of a project.

What are the key skills and qualifications needed to thrive as a Seasonal Full Stack Developer, and why are they important?

To thrive as a Seasonal Full Stack Developer, you need proficiency in both front-end and back-end programming languages (such as JavaScript, HTML/CSS, and Python), along with a relevant degree or equivalent experience. Familiarity with frameworks like React or Angular, backend systems like Node.js or Django, and version control tools such as Git are typically required. Strong problem-solving, time management, and collaboration skills help you adapt quickly to short-term projects and dynamic team environments. These skills ensure that you can deliver quality software solutions efficiently during peak demand periods.

Will Fullstack be replaced by AI?

Full Stack Developers perform complex tasks that involve designing, coding, and maintaining both frontend and backend systems, which currently require human judgment and problem-solving skills. While AI tools can assist with coding and automation, they are unlikely to fully replace Full Stack Developers in the near future, as the role relies on creativity, understanding user needs, and integrating diverse technologies. Continuous learning and adapting to new tools are important for Full Stack Developers to stay relevant in a changing tech landscape.

What are some common challenges faced by Seasonal Full Stack Developers, and how can they prepare for them?

Seasonal Full Stack Developers often face the challenge of quickly adapting to new codebases and workflows within a short timeframe. Since these roles typically support high-demand periods, developers must rapidly familiarize themselves with the team's tech stack and project requirements. Effective communication and proactive learning are key to overcoming these challenges. Collaborating closely with permanent team members and utilizing onboarding resources can help ensure a smooth integration and maximize contributions during the contract period.

Is 6 months enough for a full stack developer?

For a full stack developer, six months can provide a foundational understanding of key skills such as front-end and back-end development, but it is typically insufficient to achieve proficiency or handle complex projects independently. Success depends on prior experience, learning pace, and the complexity of tasks involved, with many developers requiring longer to become fully proficient.

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.
