Join us in building the future of digital trust. TransCrypts is building the infrastructure layer for trust in the age of AI. As automation and AI reshape the global economy, verifying identity, employment, and financial information securely becomes mission-critical. Our platform powers automated verification and compliance workflows for some of the largest enterprises in the world.

TransCrypts has raised over $20M in funding, serves hundreds of enterprise customers, and is expanding rapidly across new product categories. Our work has been featured in Forbes, Bloomberg, and The Globe and Mail.

We are assembling a small, elite engineering team focused on solving some of the hardest problems in data integrity, AI automation, and enterprise infrastructure. If you enjoy building ambitious systems that operate at scale and have real-world impact, we’d love to meet you.

About the Role

We are looking for a Senior Full Stack Engineer with a strong backend focus who thrives in a fast-moving product environment.

This role is fully in-office, five days per week, at our Toronto headquarters located at 160 Front Street W. We believe working closely together accelerates problem solving, product iteration, and engineering excellence.

You will design and build the backend systems that power our AI-driven verification platform while collaborating closely with frontend and mobile engineers to deliver complete product experiences.

This role combines:

• Distributed backend systems
• TypeScript-based backend services and APIs
• AI integrations and LLM infrastructure
• Modern cloud databases and serverless functions
• Mobile and frontend collaboration

You will take ownership of critical systems end-to-end — from architectural design through deployment, monitoring, and iteration. We value engineers who are product-minded, pragmatic, and comfortable turning ambiguous ideas into reliable systems.

What You’ll Do

Backend Systems

• Design and build scalable backend services using TypeScript and modern cloud infrastructure.
• Develop secure, well-structured REST APIs used by enterprise customers, internal services, and mobile applications.
• Build and maintain Supabase Edge Functions (TypeScript / Deno runtime) with strong production reliability including retries, timeouts, idempotency, logging, and monitoring.
• Design and evolve Postgres schemas, SQL migrations, and data models optimized for performance and security.
• Implement authentication and authorization systems using Supabase Auth and Postgres Row Level Security (RLS).

AI Infrastructure

Integrate and operate production AI systems using providers such as:

• OpenAI
• Anthropic Claude
• Google Gemini

Build backend services that support:

• multi-provider routing and failover
• structured outputs and tool calling
• streaming responses
• cost and latency optimization
• caching and rate limiting

Full Stack Collaboration

Collaborate closely with frontend and mobile engineers to deliver reliable product experiences across platforms.

Design clean, stable TypeScript-based API contracts optimized for web and mobile clients. Work closely with iOS engineers to support backend requirements for mobile features. Occasionally contribute to frontend or integration work when needed.

Technical Leadership

• Lead technically complex features from design through production.
• Mentor engineers through architecture discussions, code reviews, and technical guidance.
• Improve system reliability, developer productivity, and observability.
• Help define long-term architectural decisions as the platform scales.

The Kind of Engineer Who Thrives Here

Engineers at TransCrypts take Ownership and are builders first. We move quickly, but we care about building systems that last. We value engineers who take ownership, communicate clearly, and push projects to completion.

You’ll succeed here if you:

• Think deeply about product outcomes and user experience
• Enjoy solving complex systems problems
• Are comfortable working with
