Ownership-Driven Senior Software Engineer – Tech Startup

**Senior Software Engineer (Full\-Time, Remote) — Canada** Work Schedule: 9:00 AM \- 5:00 PM PST **About The Role** At AutoScale Ventures, we build large\-scale systems behind products like VinAudit.ca (vehicle history and data) and SquidProxies.com (proxy infrastructure). We're looking for a Senior Software Engineer to design, build, and evolve the backend systems that power these data\-heavy products in production. You'll be designing and developing critical backend components and guiding other engineers through execution. If you enjoy owning systems end to end, from design through long\-term support, this role is for you. **What You'll Do** * Design, build, and evolve backend systems that power data\-heavy production products such as market feeds, crawlers, APIs, and data pipelines. * Take ownership of major backend initiatives across their full lifecycle — design, development and implementation, rollout, and long\-term maintenance and support. * Write and maintain scalable APIs and backend services used at meaningful scale. * Lead architectural improvements and redesigns of existing systems to improve reliability, performance, and maintainability. * Break complex designs into executable components and delegate effectively when working with other engineers. * Collaborate with leadership and senior engineers on technical direction. * Mentor developers through code reviews, design discussions, and best practices. **What We're Looking For** * 5\+ years of professional software engineering or architectural experience (or equivalent depth). * A proven track record of building backend systems from scratch, launching them into production, and supporting and evolving them over time. * Experience designing and operating APIs or backend systems at scale. * Strong systems thinking — you can reason about performance, failure modes, scaling, and long\-term maintainability. * Experience in startup or startup\-like environments, or owning major systems within larger companies. * Comfort working autonomously and making high\-impact technical decisions. * Familiarity with AI\-assisted development tools (e.g., Copilot, ChatGPT, code\-generation and review tools) to support productivity and code quality. **Nice to have** * Python experience. * Experience redesigning or evolving legacy systems. * Background in data\-heavy systems (crawlers, feeds, ingestion pipelines, analytics backends). * Infrastructure or scaling experience (high\-throughput systems, reliability, performance tuning). * Experience mentoring mid\-level and senior developers. **What We Value** We're looking for someone who is curious, independent, and excited to build systems that solve real problems at scale. You should enjoy thinking beyond individual features — understanding how systems fit together, making thoughtful technical decisions, and taking ownership from initial design through production and beyond. We value engineers who can move comfortably between architecture and hands\-on development. We value someone who naturally thinks: * How should we design this to work reliably at scale? * What could fail, and how should we account for it? * Is there a simpler or more maintainable approach? * What will this system look like as it grows? * How can AI help me build, test, and improve this more effectively? * What can I improve beyond the immediate task? Most importantly, we're looking for someone who enjoys building, solving difficult problems, and taking meaningful ownership of the systems they create. **Benefits \& Perks** * Fully remote work — work from anywhere in Canada with a reliable connection. * Healthcare coverage for you and your family. * Paid leave, vacation, and holidays. * Equipment funds to set up or upgrade your work station. * Performance\-based profit\-sharing tied to the company's financial standing. * Stability and long\-term growth opportunities. * A supportive, globally distributed team culture. **About Us** AutoScale Ventures is a technology\-driven company with 50\+ team members across Canada, the U.S., the Philippines, Pakistan, India, and China. We operate a group of businesses spanning tech, data services, infrastructure, and AI, including VinAudit.com (vehicle data) and SquidProxies.com (proxy infrastructure).
