Job Description

REDspace is seeking an experienced Senior Software Developer to join our Ad Tech team. This role is crucial for architecting and evolving the systems that manage over 10 billion ad requests daily for leading media and entertainment publishers.

You will be instrumental in setting the technical direction for our ad infrastructure, influencing foundational decisions, and tackling complex implementation challenges. This hands-on position requires a deep understanding of the advertising domain, enabling you to architect across various aspects of the ad stack and provide technical leadership.

Your responsibilities will include owning the architecture of high-throughput, low-latency services, mentoring developers, and partnering closely with product owners to shape development. You will also advise leadership on technical strategy and data-handling frameworks, ensuring our systems are robust, scalable, and compliant.

Key Responsibilities

Own the architecture. Design, build, and evolve the systems behind our ad stack. High-throughput, low-latency services where performance and reliability are the job, not an afterthought.
Set technical direction. Influence the foundational decisions about how our ad systems are built and how they scale. Help set the direction, not just deliver against it.
Untangle the hard problems. Lead the resolution of the messiest issues; real-time bidding bottlenecks, data synchronization drops, broken platform integrations and provide the breakthrough on work that has stalled for weeks.
Partner with product. Work directly with advertising product owners to shape what gets built. Explain tradeoffs clearly, push back when something doesn’t add up, and propose alternatives – steering product thinking rather than just taking requirements and shipping them.
Set the standard. Mentor developers, define what developer excellence looks like in practice, and hold the bar on code review and documentation.
Advise leadership. Partner with our leadership team on long-term technical strategy and on the privacy and data-handling frameworks that govern how we work.

Qualifications

Deep, hands-on experience across the advertising domain — OpenRTB and Pre-bid, server-side and header bidding, bidstream enrichment (identity, audience, content, and supply-chain signals), ad decisioning, SSP/DSP partners, and video/CTV delivery including server-side ad insertion. You may not have touched every one of these, but you should have enough range to architect across the domain.
Strong programming and architecture fundamentals that carry across stacks. Our projects span languages and platforms. We care less about any single technology than about your ability to apply solid fundamentals to whatever a project needs. The domain knowledge is the hard requirement; the language is not.
Has built data pipelines and real-time systems at scale, and is fluent in the latency and throughput tradeoffs that come with billions of requests a day, including keeping enrichment and capture off the critical bid path.
Can step into an unfamiliar architecture, find the systemic weaknesses, and simplify it.
Anticipates major technical and regulatory shifts and factors them into architectural choices up front.

Benefits & Perks

Fully company-funded health, vision, dental, EFAP, and life insurance coverage with access to virtual doctor visits via Maple.
Pension plan contribution matching.
A flexible Health Spending Account and/or Lifestyle Spending Account.
A competitive compensation package, commensurate with experience.
Weekly sharing sessions for projects and technology.
Free access to a wide variety of training material, including access to Udemy Business.
Team-oriented education strategy, which includes a professional development allowance.
Consistent, frequent check-ins with leadership.
