Backend Engineer Jobs in Mountain View, CA

The opportunity

At Unity, we don't just help game developers build their games: we help them grow what they've built, and get their titles in front of the right players, through an ad system that makes billions of real-time decisions every day.

Every one of those decisions has to respect what a player has consented to, across dozens of jurisdictions whose rules disagree with each other and change every year. Getting that right at this scale is a permanent engineering problem. It belongs to our Ads Privacy team, which owns privacy compliance alongside the creative moderation and fraud prevention systems that keep the network trustworthy.

You will own privacy-critical services end to end, from design through production. You will work in the request path, where a wrong answer is both a legal exposure and a revenue event.

What you’ll be doing

• Build and operate the systems that carry consent and opt-out signals from the SDK through to the auction, in the request path at high QPS, owning their latency, correctness, and reliability
• Own data subject request fulfilment: orchestrating deletion across many downstream systems and teams, tracking it to completion, and holding the SLA
• Translate new and changing regulations (GDPR, CCPA) into per-jurisdiction configuration and enforcement that ships without a code change per country
• Build the measurement and auditing that proves the above is actually working, and catch it when it isn't
• Contribute to the team's wider trust and safety surface: content policy enforcement at scale, deduplication and labeling, and tooling that detects and mitigates fraud across the marketplace
• Partner with legal and privacy counsel to turn evolving requirements into working systems, and with ML and data engineers to put models and pipelines into production
• Manage your own priorities and drive work across team boundaries

What we’re looking for

• Experience designing low-latency APIs and distributed backend services running at high QPS in production
• Proficiency implementing scalable code in Golang; Java also welcome
• Hands-on experience operating services on cloud infrastructure with Kubernetes and container orchestration
• Experience with streaming platforms such as Kafka, and with event-driven system design
• Comfort working on systems where correctness is externally audited and the requirements come from outside engineering
• Effective written and verbal communication, and the ability to work effectively in multi-functional teams

You might also have

• Experience in AdTech, and familiarity with IAB frameworks such as TCF
• Background in privacy engineering, trust and safety, or fraud detection
• Working knowledge of global privacy and data regulations (GDPR, CCPA, and the frameworks that keep following them)
• Experience with SQL, NoSQL, and key-value stores such as Postgres, MongoDB, and Redis
• Experience working alongside ML engineers or data teams to put models and data pipelines into production
• Familiarity with infrastructure-as-code and observability tooling such as Terraform, Prometheus, Grafana, or OpenTelemetry
