Senior Software Engineer (Basis Platform / DSP)

Requirements

• Ownership. You run with autonomy and own what you ship — quality, reliability, and what happens after it hits production. You're at home driving projects from first sketch to launch and beyond.
• Relentless Curiosity. You close your own gaps in knowledge, skill, and domain — and that depth shows up in planning, where you catch risks early and keep the technical path aligned with the business goals.
• Leadership. You lead projects end-to-end across our stack, set the bar for quality, and pull other engineers up with you.
• Collaboration. You demonstrate strong partnerships and communication skills through pull requests, demos, and working relationships.
• Positivity. You bring a sense of strategic optimism and a solution-oriented mindset to work, while embodying Basis' core principles.
• 5+ years professional software development experience.
• Proven experience designing, building, and scaling modern, production‑level front‑end experiences using React, with supporting back‑end work in Ruby on Rails.
• Current with modern development practices, including AI‑assisted and agentic workflows for code generation, debugging, exploring, and documentation.
• Strong grasp of data modeling and system design.
• Enthusiastic growth-oriented mindset.
• (Desirable) Bachelor’s degree in Computer Science, Engineering or related field.
• (Desirable) Experience with Spring Boot, Quarkus.
• (Desirable) Excited by a fast‑paced product development environment.
• (Desirable) Passion for Ad‑Tech.

What the job involves

• Our team sits at the nexus between the flagship Basis Platform application and our Demand‑Side Platform, a real‑time auction engine that competes in billions of ad auctions a day, each with a sub‑100ms latency.

• We deal in data, and lots of it! Implementation is not just code and structure, we consider resources, performance, and scalability.
