Senior Full-Stack Engineer

Tetra Digital Group is Canada's leading institutional digital asset infrastructure provider, and right now, we're at an inflection point five years in the making.

As Canada's first and only regulated digital asset custodian, we've built the institutional foundation the market now demands. We're backed by Urbana Corporation, National Bank, ATB Financial, Wealthsimple, Purpose Unlimited, Shakepay, Shopify, and Coinbase Ventures — some of the most consequential names in Canadian finance and fintech.

We operate two interconnected businesses:
Tetra Trust
, our regulated custody arm and CADD
, a compliant on-chain payment rail backed 1:1 by Canadian dollars.

In May 2026, we launched CADD — Canada's first CAD-backed stablecoin issued by a regulated financial institution — following approval from Alberta Treasury Board and Finance. It's live on Base, Ethereum, and Tempo today, with Solana next. Coin Desk and BNN Bloomberg covered it as the arrival of Canada's first regulated digital dollar.

Here's the problem we're actually solving:
Canada clears roughly $424 billion every business day
, and much of the retail payment infrastructure underneath it was designed in the 1980s. Batch windows. Cut-off times. Weekends off. We're the team replacing that with rails that settle continuously, programmatically, and under real regulatory oversight.

We're a team of under 30. The infrastructure we've built punches well above that number, and so does the opportunity ahead.

You’ll build the surfaces institutions actually touch.

That means the APIs a bank integrates against, the console our operations team uses to move real client assets, the mint-and-redeem flows behind CADD, and the reconciliation views that let a client's finance team prove their numbers to their own auditors. Less "growth dashboard," more "this endpoint is load-bearing."

Here's the part we'd rather say out loud than have you discover in week three:
there is no undo button. A bad deploy at a social app means a bad afternoon. A bad deploy here means a client's assets moved when they shouldn't have, or didn’t move when they should have — and the list of crypto companies that learned this lesson publicly is long, permanent, and easy to Google.

We're not telling you that to scare you off. We're telling you because the engineers who find that interesting rather than exhausting are exactly who we want. If you've ever cared more about a correct ledger than a clever abstraction, keep reading.

You’ll report to [Head of Engineering / CTO] and work alongside a small, senior team where nobody's work is hidden behind three layers of process.

• Client-facing APIs and integrations. The interfaces banks, brokerages, asset managers, and payment companies build against. Designed once, versioned carefully, broken never.
• Internal operations tooling. The least glamorous, highest-stakes software in the building. Our ops team uses it to authorize movements of real money. It needs to make the right action easy and the catastrophic action nearly impossible.
• CADD product surface. Mint, redeem, attestation reporting, and the partner-facing tooling around Canada's first bank-issued CAD stablecoin.
• Correctness as a feature. Ledger integrity, idempotency, reconciliation, replay safety. You’ll write the tests that let all of us sleep.
• Audit-ready by default. Institutional clients and provincial regulators ask hard questions about how things work. You’ll build systems that answer those questions without an archaeology project.
• On-call, shared. You’ll be in the rotation with everyone else who touches production. We keep it humane and we staff it properly — see the note on fit.

• 5+ years shipping production software you were accountable for after launch —…
