Senior Full-Stack Developer (WealthTech) — Montreal (Hybrid)

About Sofistic.AI

Sofistic.AI is the AI-native intelligence platform for wealth management. Powered by Sofi, our intelligence layer, we give advisors a persistent, 360° view of each client’s full financial picture and surface the right insight at the right moment — turning 4 client touchpoints a year into 50+. And because client data never leaves the advisor’s secure environment, no general-purpose AI can replicate what we do. We’re SOC 2 Type II, already trusted by major financial institutions and family offices, and scaling from Canada into the US and beyond.

The role

We’re looking for a senior full‑stack developer who ships. You’ll own features end‑to‑end — frontend to backend to production — on a small team where your work reaches customers in days, not weeks. This isn’t a role where you wait for tickets. You’ll shape technical decisions, break big problems into small reversible releases, and use AI as a daily force multiplier. If you want real ownership at the core of a product that’s scaling, this is it.

What you’ll do

• Own features across the stack — design, build, test, deploy, and operate them in production.
• Ship small, incremental, reversible changes to production daily using trunk‑based development.
• Make pragmatic architectural calls: modular services, scalable by design, cost‑conscious.
• Write well‑tested code and lean on automation for testing, deployment, and operations.
• Integrate AI into your own workflow and the product where it creates customer value.
• Review peers’ work, raise the engineering bar, and mentor where it helps the team move faster.
• Tie technical decisions to customer and business impact — and push back when something doesn’t.

What we’re looking for

• 5+ years building and shipping production web applications, full‑stack.
• Strong React and TypeScript; solid backend experience (Node.js or similar).
• Comfortable owning the full lifecycle: API design, data modeling, testing, CI/CD, deployment, monitoring.
• Experience with cloud infrastructure (AWS preferred) and modern deployment practices.
• A track record of frequent, low‑risk releases — you think in increments, not big‑bang launches.
• Strong ownership instinct and sound judgment under ambiguity; you make the good‑enough call and adjust.
• A clear communicator who collaborates well with product, design, and other engineers.

Bonus

• Fintech / wealth / financial‑data experience.
• AI/ML integration experience (LLMs, RAG, agentic workflows).
• Serverless judgment — including knowing when not to use it.
• Experience in a regulated, compliance‑driven environment (SOC 2, privacy).
• Bilingual (English / French).

How we engineer

We optimize for speed without breaking quality.

• Trunk‑based development, short‑lived branches, frequent merges into main.
• Multiple safe production deploys per day; small, reversible increments.
• AI‑first — we continuously adopt tools that measurably improve how we work.
• Metrics‑driven, automation‑first, cost‑conscious by design.
• Fast decisions: aim for good‑enough and adapt, time‑box research, 80% agreement but 100% alignment.

Why join

• Ground floor of a well‑backed, fast‑scaling company — experienced leadership and a seasoned board behind it.
• Real ownership: your code reaches customers in days, and you help shape both the product and the engineering culture.
• A bright office right on the water in Old Montreal — just off the bike path, with plenty of bike parking. Walk, bike, or run in.
• Breakfast and lunch on us, and Thursday 5‑to‑7s.
• Hybrid flexibility — 3 days in office, 2 remote.
• A flexible personal allocation you can put toward wellness or your RRSP.
• Time off that’s actually meant to be taken.
• A team that takes the work seriously without taking itself too seriously.
