Full Job Description
Description
Full Stack Developer (AI-Native)

What we value

- Urgency and initiative: moving things forward without waiting to be told

- Ownership and commitment: you treat this like it's yours, because it is

- Humility and ego-free collaboration: strong opinions, loosely held; quick to be wrong; quicker to learn

- Hard work in service of clear, measurable goals: output, not theatre

- Genuine curiosity about what's now possible with AI: paired with the discipline to know when AI output is wrong and push back on it

- Care for security, privacy, and boundaries: our customers trust us with sensitive financial data, and that trust is non-negotiable

- Transparency and honesty in how we work and what we ship

- Driving and enabling value for clients, prospects, and teammates

- Relationship building and follow-through, both internally and with customers

- Relentless attention to improvement

The Opportunity

You'll take ownership of meaningful slices of the product end-to-end. You'll design, develop, and ship secure, scalable web applications on AWS, and you'll do it using the best AI-assisted tooling available.

This role suits someone who

- Has shipped real production code in real systems with real consequences

- Is already using Claude Code or similar tools in their daily workflow, not just experimenting on weekends

- Knows when to trust AI output and when to validate, push back, and iterate

- Cares about how the product feels for the user, not just whether it works

- Treats security as a feature, not a checkbox

- Doesn't need a six-person team and a three-week estimation cycle to get moving

Your Responsibilities
Backend Development

- Design and build robust server-side applications, business logic, and data processing pipelines

- Write efficient, scalable, secure code

- Optimize database queries and application performance

- Implement RESTful APIs and integrate with third-party services

Frontend Development

- Build responsive, intuitive interfaces using modern frameworks (React preferred)

- Translate designs into interactive pages with strong usability and UX

- Ensure cross-browser compatibility and adherence to web standards

Database Management

- Design, optimize, and maintain relational databases (MySQL in our current stack)

- Implement schemas, indexes, and relationships that protect data integrity and performance

- Perform migrations, backups, and data migration tasks as required

AWS Cloud Infrastructure

- Deploy, configure, and operate applications and services on AWS (EC2, RDS, S3, Lambda, ALB, and others)

- Build scalable, fault-tolerant architecture using ELB, Auto Scaling, Route 53

- Monitor and optimize performance, scalability, and cost-efficiency

- Apply IAM and AWS security best practices in everything you ship

AI-Native Development

- Use Claude Code (or equivalent agentic tools) as a core part of your workflow, not as a novelty

- Parallelize work across multiple AI workstreams where it genuinely accelerates output

- Develop the judgment to validate AI-generated code, recognize when it's wrong, and iterate to a correct result

- Share patterns, prompts, and learnings with the team, as we are all levelling up together

Security and Boundaries

- Apply web security best practices throughout development: input validation, authn/authz, secrets management, dependency hygiene

- Be thoughtful about blast radius: changes can ripple across clients with different configurations and workflows

- Recognize when an AI tool is about to cross a privacy or security line and act accordingly

- Treat customer data with the seriousness it deserves

Collaboration and Communication

- Work closely with our Engineering Lead and the rest of the engineering team

- Participate in code reviews, technical discussions, and knowledge sharing

- Communicate progress, blockers, and recommendations clearly and early

Requirements

Required

- 5+ years of professional Full Stack Development experience in production systems

- Hands-on AWS experience deploying, operating, and scaling real workloads. This is non-negotiable; our entire platform runs on AWS.

- Strong proficiency in a modern backend language and a relational database

- Experience with React (or a comparable modern frontend framework), plus solid HTML / CSS / JavaScript fundamentals

- Active, recent experience using AI-assisted development tools (Claude Code, Cursor, Copilot, agentic workflows) in real day-to-day work, not just dabbling

- Solid grasp of web security best practices

- A demonstrably curious, builder-oriented mindset; you should be able to point to something you've built or shipped recently outside of your day job

- Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent demonstrated experience

Preferred

- Experience with PHP and MySQL. This matches our current platform and will help you ramp faster, but isn't a hard requirement if your AWS and modern-stack experience is strong.

- Prior experience on a small, high-velocity team

- Multi-tenant SaaS experience

How we'll evaluate

A traditional interview loop won't surface the right person. Expect a process that looks more like:

- A short conversation about what you're building with AI right now, in your own time

- A practical exercise where you'll work on a real-shaped problem using your own AI-assisted workflow; we want to see how you actually work, not how you perform

- A working session with our Engineering Lead and the engineering team

If your instinct is to ask for a detailed spec before starting, this probably isn't the right fit. If your instinct is to come back with something better than we asked for, it almost certainly is.

Your Benefits

- Meaningful stock options: this is a small team and the equity reflects it. We expect ownership, and we share the upside.

- Excellent medical, dental, and vision plans

- Base salary: $120K-$140K CAD

- Real autonomy and real accountability

- Career growth in an early-stage company doing genuinely novel work

- New MacBook and accessories

Location

We're looking for candidates based in Vancouver, BC or Calgary AB.

Compensation

$0.00 - $0.00 per year
