Our partner is looking for a Software Engineer, Trust & Safety based in Canada. Join a fully remote engineering team building reliable email infrastructure for millions of developers worldwide. As a Software Engineer specializing in Trust & Safety, you will design and develop sophisticated anti-abuse systems that protect legitimate senders while preventing spam, phishing, fraud, and account compromise.

You will build real-time enforcement mechanisms, scalable detection pipelines, and automated workflows that turn security signals into effective action within milliseconds. Working across backend services, infrastructure, databases, and machine learning, you will help strengthen platform security without compromising the experience of legitimate users. You will have significant ownership over technical decisions, from initial discovery through production deployment.

This role offers the opportunity to solve complex engineering challenges in a quality-focused, collaborative, and globally distributed workplace. Design scalable detection pipelines that transform signals from email sending, receiving, and account activity into decisions and automated actions. Develop, maintain, and improve detection rules and enforcement policies, ensuring they can be updated safely and evaluated consistently.

Detect and contain account takeovers and leaked API keys by identifying suspicious behavioral changes and limiting potential damage while avoiding unnecessary account lockouts. Build, evaluate, and deploy machine learning classifiers for spam and phishing detection, validating their precision before enabling automated enforcement. Contribute across the full technology stack, including frontend interfaces, backend services, databases, queues, and supporting infrastructure.

Collaborate with engineering colleagues and developers using the platform to understand real-world needs and deliver effective, dependable solutions.



Take ownership of projects from discovery and technical design through implementation, production deployment, and continuous improvement. At least five years of professional software engineering experience.

Strong written and spoken English communication skills. Deep hands-on experience with Node.js, TypeScript, and React, ideally including frameworks such as Hono and Next.js. Solid infrastructure and reliability engineering skills, including experience with AWS, AWS CDK, and Datadog.

Strong observability practices, including metrics, logging, distributed tracing, error handling, and production monitoring. Ability to take ownership across the stack, from frontend applications to backend services, databases, and messaging infrastructure. Proven experience working with PostgreSQL and Redis.

Previous experience in trust and safety engineering, fraud prevention, cybersecurity, or abuse detection.

Experience building real-time enforcement systems, such as rate limiting, or rules engines using policy languages such as CEL.

Experience deploying machine learning or large language model-based detection systems in production, including measuring precision and recall. Knowledge of email security and deliverability concepts, including SPF, DKIM, DMARC, bounces, complaints, and phishing campaigns.

Experience with PostgreSQL and Redis performance tuning. Fully remote working arrangement for candidates based in the Americas or European time zones, subject to role eligibility. Opportunity to influence technical architecture and engineering decisions.

Ownership of projects from discovery through production deployment. Close collaboration with developers who use the platform and benefit directly from the systems you build. A strong focus on software quality, infrastructure reliability, and excellent developer experience.

Opportunities to attend team offsites, conferences, meetups, and other professional gatherings, with some travel expected. #
