Ownership-Driven Senior Software Engineer – Tech Startup

Work Schedule:

9:00 AM - 5:00 PM PST

At Auto Scale Ventures, we build large-scale systems behind products like  (vehicle history and data) and  (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.

• 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.

• 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.

• 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.

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.

• 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.
