Software Engineer (Moderation, Trust & Safety)

Era is building the AI orchestration layer for the next generation of physical devices. We power intelligence across headphones, wearables, home objects, and entirely new device categories. Every one of those devices needs to know who it's talking to and protect them.

We've raised $10M+ from Abstract, Topology, BoxGroup, Betaworks, Collab Fund, and Mozilla Ventures.

The Role

Every Era-powered device is an intimate object. It listens, it speaks, it lives in someone's ears or on their body or in their home. That intimacy only works if it's built on trust: the user has to know who they are to Era, the device has to know it's really talking to Era's cloud, and every interaction has to be safe across wildly different brand contexts and demographics.

You own that trust layer end-to-end. That means identity and authentication across a fleet of physical devices and the consumer app, and it means the moderation and safety systems that keep every experience appropriate, protected, and abuse-resistant. You sit between infrastructure and AI, and you're the person who makes sure Era is something people can trust with their lives.

What You'll Do

• Own Era's identity platform - authentication, authorization, session management, and device identity across the consumer app and a growing fleet of physical devices (Ory, Auth0, or custom)
• Build the trust fabric - how a user proves who they are across every device they own, how each device proves who it is to the cloud, and how permissions and consent flow across the ecosystem
• Design and operate content moderation systems - real-time safety guardrails that protect users and partners across different brand contexts, age groups, and demographics
• Build safety frameworks for AI interactions - content filtering, demographic-aware moderation, age-appropriate experiences, and configurable guardrails per partner
• Adversarial-test the platform - prompt injection, jailbreaking, account takeover, and the abuse vectors that emerge when real users interact with physical devices in unpredictable environments
• Handle sensitive data responsibly - encryption, PII handling, consent management, and data retention across jurisdictions
• Work with third-party software vendors and service providers to allow their API/SDK/MCP endpoints to be securely called and run on Era’s Core platform.
• Build real-time detection and response - systems that catch harmful content, abuse, and safety incidents across thousands of active devices and act on them fast
• Partner with brand partners on their trust & safety requirements, from COPPA to GDPR to the EU AI Act

What We're Looking For

• Production experience building identity/auth systems - OAuth/OIDC, session management, SSO, or device identity (Ory, Auth0, or equivalent)
• Background in trust & safety or content moderation at a consumer-facing platform
• Strong programming skills across Python and TypeScript
• Real understanding of AI safety and responsible deployment - content guardrails, demographic-aware moderation, red-teaming
• You think adversarially. You anticipate how systems get abused before they do, and you design for the worst case
• Familiarity with compliance frameworks relevant to consumer devices and AI (COPPA, GDPR, EU AI Act)
• You care about protecting people. These are real users on real devices, and the stakes are real

Nice to Have

• Experience with real-time moderation of audio/voice systems
• Background scaling identity or trust infrastructure to 100k+ users or devices
• Privacy-preserving techniques - encryption, differential privacy, on-device processing
• Abuse detection, anomaly detection, or fraud systems experience
• Red-teaming or adversarial ML experience

You at Era

Most trust & safety work is bolted on after the fact. Here, you get to design it into the foundation of a brand-new device category, before millions of people are relying on it. You'll decide what identity, consent, and safety mean for ambient AI - and you'll build the systems that make Era something people trust in their most personal moments.
