Senior Software Engineer II, (AI Native)

the opportunity to shape the future of our offerings while collaborating with senior engineers and mentoring junior team members. Your work will directly influence our ability to remain competitive and responsive to market trends, making this an exciting time to join our team. For candidates based in the US, the salary range for this position is $118,500 to $216,500 USD. For candidates based out of Canada, the salary range for this position is $171,500 CAD to $201,000 CAD. Note: Please be aware that the job title for positions in Canada will be "Developer" in lieu of "Engineer." We take into consideration an individual's background and experience in determining final salary - therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity. What You’ll Do Build and maintain high-throughput backend services on the AdServer and Exchange platform, contributing to reliability, scalability, and performance targets. Implement and improve Real-Time Bidding and auction logic, and support integrations with demand and supply partners. Collaborate with Staff Engineers and architects to execute on platform design decisions and raise concerns where you see gaps. Own features end-to-end — from design through deployment — with a focus on correctness, observability, and operational health. Partner with Product on new ad formats and monetization capabilities, translating requirements into solid technical designs. Contribute to monitoring, incident response, and root cause analysis to improve overall platform reliability. Use AI tooling (including Claude Code) as a day-to-day collaborator — generating scaffolding, drafting schemas, and accelerating code review. Mentor junior engineers and contribute to team standards around code quality, testing, and engineering practices. What We’re Looking For Bachelor's degree in Computer Science, Engineering, or a related field. 5–8 years of backend engineering experience, with strong proficiency in Java and multi-threaded system design. Experience building or operating high-throughput, low-latency distributed systems in production. Solid understanding of data consistency, performance trade-offs, and database fundamentals. Comfort working in cloud-native environments, ideally AWS. Familiarity with AdTech concepts (RTB, auctions, supply/demand integrations) is a plus. Experience integrating third-party APIs or partner systems is a plus. Clear, direct communication — you can explain a technical decision to an engineer or a product manager without losing either of them. Openness to using agentic workflows and AI-assisted development to reduce cycle time and operational overhead. AI-Native Expectations We use AI coding tools as a professional standard on this team. Here's what that means in practice: Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete. Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship. Velocity: We expect senior engineers who use AI well to operate with meaningful leverage — doing more with the same time, taking on problems that would otherwise require a larger team. Team leadership: You share what works. You automate prompting strategies that others can build on and help teammates earlier in their AI workflow adoption get up to speed. Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. Our Benefits Medical, dental, vision, life and disability insurance plans (100% paid for US employees). We offer life and disability as well as supplemental plans for medical and dental for Canadian employees. 401(k) plan with company matching program in the US and RRSP with DPSP plan for Canadian employees. Paid parental leave Mental Wellness Program & Employee Assistance Program (EAP) for mental well-being Generous time off: flexible PTO, companywide holidays throughout the year plus summer and winter shutdowns Learning & Development programs Equipment, tools, and reimbursement support for a productive remote environment.
