Job description

Tetra Trust Company is Canada’s first qualified custodian for digital assets and is on a mission to unlock the digital asset industry for institutional investors. Founded in 2019 to meet the growing need for institutional custody in Canada, Tetra’s vision is to grow into a full-service financial platform and infrastructure provider for the digital asset space.

Tetra provides a solution to one of the last remaining problems preventing institutional adoption of the digital asset industry - custody. Tetra is a rapidly growing, well-funded company. You’ll be afforded all the benefits of joining a larger company with the flexibility and independence to grow Tetra into a world class company.

Tetra Trust is looking for a seasoned Senior Full Stack Developer who is ready to roll up their sleeves, lead by example, and grow into a pivotal leadership role within our technology team. This position starts as a hands-on development and technical lead role, and for the right person, it will evolve into working closely with the CTO to shape our technical direction, architecture, and team growth.

You will lead our current team of developers, providing mentorship, guidance, and clear direction. If you love building great products, mentoring others, and want a leadership path without stepping away from code, this is your opportunity.

This role is based in Toronto with a structured hybrid work model of at least 3 days in the office per week. This role requires a full-time office work model during the first month for training.

Key Responsibilities

• Take ownership of critical features and systems across the stack (frontend, backend, infrastructure)
• Lead our existing team of developers and provide day-to-day technical oversight
• Collaborate directly with the CTO to design and deliver scalable, performant solutions
• Mentor other developers and promote engineering excellence and knowledge sharing
• Contribute to architectural decisions and long-term technical strategy
• Establish and maintain coding best practices, development standards, and technical documentation
• Help drive hiring, onboarding, and the evolution of our engineering team
• Leverage AI tools and techniques to automate tasks, enhance efficiency, and optimize development processes
• Gradually step into a broader leadership role as trust, experience, and team size grow

Our Current Tech Stack

(This stack will continue to evolve — your input will help shape it)

• Frameworks & Languages: React 18, TypeScript, Go (Golang)
• Bundler & Dev Tools: Vite, SWC, Jest, ESLint, Prettier
• Routing & State: React Router, React Hooks
• Styling: Sass, CSS Modules, Vite SVGR for SVG components
• Database: PostgreSQL using Kysely (type-safe SQL query builder)
• Infrastructure: AWS

What we are looking for

• 5+ years of full stack development experience with strong proficiency in modern JavaScript/TypeScript and backend development
• Hands-on experience with blockchain technologies and decentralized systems
• Experience leading small teams or acting as a tech lead on complex projects
• Strong understanding of scalable architecture, clean code practices, and CI/CD workflows
• Confident in making architectural and technical decisions and explaining trade-offs
• Clear communicator who thrives in collaborative environments
• Self-driven and eager to take ownership, but comfortable asking for help when needed
• Excited about growing into a technical leadership role
• Comfortable exploring and working with new languages and paradigms like Go (Golang)

Nice to have

• Experience working in fintech, Web3, or regulated environments
• Exposure to secure application design and infrastructure practices
• Prior startup or fast-growth company experience
• Familiarity with design systems or building reusable component libraries

Why choose Tetra

• Exciting Industry: Be part of a rapidly growing company at the forefront of financial innovation.
• Hands-on Role: You will have a direct impact on the company’s growth by leading sales efforts and developing new client relationships.
• Career Growth: As a key member of the team, you’ll have the opportunity to grow your career within a fast-paced, expanding company.
• Competitive Compensation: We offer a competitive salary, performance-based incentives, equity options, and a comprehensive benefits package.
