Top Tech Jobs & Startup Jobs in Toronto

Own Alexandria’s provider pipeline from sourcing and cold outreach through negotiation, signed agreements, onboarding, and live catalog listings. Identify high-value data, content, research, government, and other sources; structure licensing, pricing, revenue share, attribution, and usage terms; collaborate with legal and engineering; develop a self-serve contributor program; and feed provider insights into product strategy. Requires experience closing data, content, or API marketplace deals and technical fluency with APIs and MCP.

Designs and operates public, automated benchmarks for data providers. Owns datasets, ground truth, scoring methodology, reproducible evaluation harnesses, weekly releases, public leaderboards, and integration of benchmark results into Alexandria’s provider-selection system. Measures accuracy, coverage, freshness, speed, and cost while communicating findings to engineers, marketers, and vendors.

Research and reverse-engineer web anti-automation systems, including browser detection, challenge flows, fingerprinting, and obfuscated JavaScript. Build and deploy browser automation, diagnostic, and monitoring infrastructure that improves scraping reliability across a large crawling fleet. Measure scrape success, investigate regressions, and ship production fixes quickly while collaborating with platform engineers.

Own enterprise security and deployment requirements from discovery through shipped platform capabilities. Build reusable cloud and on-premises infrastructure supporting key management, tenant isolation, compliance integrations, and hybrid or multi-cloud deployment. Partner with sales, founders, and platform engineers, communicate designs to enterprise security teams, and directly implement solutions in TypeScript and Node.js.

Build and own Firecrawl’s Marketplace Exchange, turning signed data partnerships into live, permissioned, metered, and billable API integrations. Responsibilities include provider catalog development, routing partner data through the API, feed ingestion, access gating, usage metering, billing and payout reporting, and creating reusable integration patterns. The role requires strong product sense, developer experience focus, end-to-end ownership, and the ability to work effectively on ambiguous problems in a fast-paced onsite environment.

Build and ship developer-facing document-parsing products from concept through production. Own parsed-output reliability across PDFs, Word documents, spreadsheets, scanned files, and mixed formats. Solve layout detection, table structure, reading order, and OCR-routing challenges while creating intuitive APIs. Collaborate on roadmap decisions, use the product, monitor developer feedback, and rapidly iterate based on real customer needs.

Build and operate GCP and on-premises infrastructure supporting high-throughput crawling, search, queues, databases, and ML workloads. Manage Kubernetes clusters, CI/CD, infrastructure as code, observability, enterprise security controls, reliability targets, cost optimization, and incident response. Partner with product and search engineering teams to productionize services and own infrastructure from design through operation.

Build and ship developer-facing API features end-to-end for a web-to-LLM data platform. Own reliability and developer experience, design clean APIs, dogfood the product, collaborate on roadmap tradeoffs, and iterate quickly based on real developer feedback. Requires prior experience shipping developer-facing products.

Build and maintain infrastructure for reliable, large-scale web data collection. Improve success rates against sites with aggressive defenses, own proxy layer health/rotation/cost, push throughput under spiky load, and debug intermittent failures. Own systems end-to-end in production.

The Research Engineer will design and build evaluation systems to measure data quality for Firecrawl's web data extraction, creating metrics and benchmarks, and collaborating on model improvements.
