We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and a commitment to balancing Family along the way. These values are the foundation of our work, and we are committed to upholding them in everything we do. Our co-founders are Bret Taylor https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/. Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps.

Before that, Clay led the product and design teams for Google Workspace. ABOUT THE HEALTHCARE TEAM - Our healthcare agents already reach over 50% of U.S. families. We partner with leading health plans, providers, and healthcare platforms to deliver AI agents that handle some of the most sensitive and high stakes conversations in any industry. From helping members understand their benefits to resolving billing questions with empathy, our healthcare agents are transforming how patients and policyholders interact with the healthcare system. - Our healthcare customers include major health insurance networks, nonprofit providers, multi-site primary and urgent care practices, healthcare diagnostics companies, and healthcare financial platforms. - Join us to transform the patient experience across the healthcare system—and help build technology that makes care more accessible, more human and more affordable for everyone. WHAT YOU'LL DO - Design integrations grounded in real healthcare workflows. Translate customer requirements into clear recommendations on interfaces, data flows, and EHR configuration. Identify assumptions, tradeoffs, and limitations so engineering teams have an actionable implementation plan. - Resolve customer-specific EHR complexity. Understand how each organization configures and operates its EHR, including scheduling rules, patient identity, permissions, and workflow dependencies. Work with customer analysts, vendor teams, and Sierra engineers to investigate unexpected behavior and resolve integration blockers. - Guide integration readiness through go-live. Define customer setup requirements, dependencies, and validation criteria. Guide EHR and IT teams through application registration, access provisioning, environment setup, and workflow testing, partnering with engineers to verify that integrations behave as intended. - Bring EHR expertise to customer discovery. Partner with Sales, Sales Engineering, and Agent Development to assess feasibility, explain integration requirements, and scope achievable projects. Make clear what Sierra supports today and what requires additional configuration or development. - Shape Sierra’s healthcare integration roadmap. Evaluate vendor capabilities, integration programs, and emerging customer needs. Recommend where to invest, distinguishing reusable platform capabilities from customer-specific configuration and implementation work. - Make each implementation easier than the last. Turn deployment experience into reference designs, implementation guides, and internal training. Help teams apply proven approaches and recognize when a customer’s requirements call for a different design. WHAT YOU'LL BRING - 5+ years of experience in healthcare interoperability or EHR implementation, with direct responsibility for designing or delivering integrations at an EHR vendor, health system, healthcare technology company, or implementation consultancy. - Deep expertise in at least one major EHR ecosystem, such as Epic, athenahealth, Oracle Health, eClinicalWorks, MEDITECH, or similar systems. You understand its integration options, configuration model, and implementation processes, and can investigate unfamiliar capabilities independently. - Practical knowledge of patient-access workflows, such as scheduling, registration, or referral management. You can explain how operational rules and customer configuration affect what an integration can do. - Technical fluency in healthcare integrations. You can read API documentation, interpret requests and responses, and troubleshoot data and configuration issues. You have hands-on experience with relevant approaches such as FHIR, HL7v2, vendor APIs, or file-based exchange, and can explain when to use them. - A track record of taking third-party integrations through deployment. You have worked through application registration, authentication and permissions, test and production environments, workflow validation, and go-live dependencies. - Clear communication and independent judgment. You can lead discovery with EHR analysts and operational teams, turn incomplete information into an implementation plan, and explain recommendations to software engineers and business stakeholders. You know when to validate an assumption before committing to an approach. EVEN BETTER... - Epic certifications in areas such as Bridges, Cadence, Prelude, or Interconnect, or comparable expertise in another EHR ecosystem. - Experience across multiple EHR vendors or health systems, particularly integrating third-party products into patient-access or contact-center workflows. - Experience using SQL, scripts, or code to investigate integration issues, or working with teams building AI agents for healthcare. - Hands-on software development experience, including building or extending integrations with EHRs or other healthcare systems. - Comfortable contributing directly to integration code, including implementing API calls, troubleshooting failures, and writing tests. Experience with TypeScript, Go, or Python is a plus. OUR VALUES - Trust: We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work. - Customer Obsession: We deeply understand our customers’ business goals and relentlessly focus on driving outcomes, not just technical milestones.

When we notice something isn’t right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve. - Intensity: We know we don’t have the luxury of patience. We play to win. We care about our product being the best, and when it isn’t, we fix it. When we fail, we talk about it openly and without blame so we succeed the next time. - Family: We know that balance and intensity are compatible, and we model it in our actions and processes. We are the best technology company for parents. We support and respect each other and celebrate each other’s personal and professional achievements.

Location: Toronto; Calgary; Boston; Canada; Seattle; New York; Vancouver; California; Ottawa; Montreal Workplace: Remote WHO ARE WE? Cohere is the leading security-first enterprise AI company. We build cutting-edge foundation AI models and end-to-end products that are designed to solve real-world business problems. We’re training and deploying frontier models for enterprises who are building AI systems. We believe that our work is instrumental to the widespread adoption of AI and we are looking for folks that want to be part of that. We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. Cohere is a team of researchers, engineers, designers, and more, who are all passionate about their craft. We are a global technology company headquartered in Toronto with key offices in London, New York City, San Francisco, Montreal, Paris, Berlin and Seoul. Join us! WHY THIS ROLE Enterprises hand Cohere their most sensitive data and put our models inside workflows they can't afford to get wrong. Securing that means working on problems the industry hasn't settled yet, what authorization means when an agent acts on a user's behalf, how to contain tools that consume untrusted input, and whether tenant boundaries hold when a model can be steered by the data it reads. The established playbooks only take you so far. We're hiring a Senior Product Security Engineer to work these problems alongside the engineers building the products, reviewing architecture and code, threat modeling before implementation, testing what ships, and turning what you learn into defaults other teams inherit. This is a hands-on engineering role, not an advisory one. WHAT YOU’LL DO - Lead security reviews. Review architecture, code, and security-sensitive changes. Identify both individual vulnerabilities and the recurring design patterns behind them. - Secure AI-powered products. Evaluate risks such as prompt injection, unsafe tool use, identity and delegation failures, excessive agency, data exposure, tenant isolation, and sandbox escapes. - Threat model new capabilities. Identify trust boundaries, abuse cases, and high-impact failure modes before implementation. Translate findings into practical, prioritized mitigations. - Perform hands-on testing. Investigate suspected vulnerabilities, develop proofs of concept, assess exploitability and impact, and partner with engineers through remediation. - Build scalable guardrails. Develop secure defaults, approved patterns, reusable controls, review requirements, and automated checks that reduce recurring risks. - Strengthen engineering capability. Pair with engineers, document practical guidance, and help product teams develop durable security expertise. - Influence risk decisions. Explain technical findings, business impact, and remediation options clearly to engineers, product leaders, and executives. YOU MAY BE A GOOD FIT IF - You have strong software engineering fundamentals and can independently understand, test, and contribute fixes to production codebases. - You are proficient in at least one of Python, Go, or TypeScript. - You have led security reviews or threat models for complex production systems and can point to meaningful design or risk improvements that resulted. - You understand common vulnerability classes and their underlying design failures, including injection, authorization flaws, IDOR, SSRF, unsafe deserialization, race conditions, cryptographic misuse, and software supply-chain risks. - You understand modern application architecture, including web applications, APIs, OAuth/OIDC, cloud platforms, containers, Kubernetes, and CI/CD systems. - You can reason rigorously about untrusted input, authorization, isolation, identity, delegation, and data boundaries. Direct experience with agentic AI systems is valuable but not required. - You have driven security improvements involving multiple engineering teams, including situations where influence mattered more than authority. - You communicate clearly with both technical and non-technical audiences. NICE TO HAVE - Experience building or operating security tooling such as SAST, DAST, SCA, custom linters, or policy-as-code. - Experience securing multi-tenant SaaS, enterprise software, or systems that process sensitive customer data. - Offensive security experience through penetration testing, red teaming or security research. - Experience operating or participating in a vulnerability disclosure or bug bounty program. - Contributions to open-source security projects, published research, conference talks, or credited vulnerability discoveries. FULL-TIME EMPLOYEES AT COHERE ENJOY THESE PERKS: - A weekly lunch stipend of $75/£75 or equivalent in your local currency for lunch. - Full health and dental benefits, including a separate budget for mental health. - RRSP matching, 401K, Pension Scheme. - 100% Parental Leave top-up for up to 6 months, for either parent. - Annual enrichment benefits: Arts & culture, fitness/wellness, quality time, and a workspace improvement credit. Education & learning stipend for conferences, courses, and coaching. - 6 weeks of paid vacation (30 working days!) - Budget for traveling to other offices if you are remote, plus an annual company offsite. HOW AND WHERE WE WORK: - Cohere is remote-friendly, but we also have offices in Toronto, London, New York City, San Francisco, Montreal, Paris, Berlin and Seoul with more opening soon. - For those in the office: a daily lunch program, plenty of snacks, and regular community and social events. - For those not near an office: a co-working benefit so you can work alongside others in your city. - Everyone receives a $500 home office stipend to set up your workspace properly. If any of the above doesn’t line up exactly with your experience, we still encourage you to apply. We strive to create an inclusive work environment for all; we welcome applicants from all backgrounds and are committed to providing equal opportunities. Should you require any accommodations during the recruitment process, please submit an Accommodations Request Form https://docs.google.com/forms/d/12a6IrLdF3kI2nonKSr4tiFuz18rLQbaeYV-JM9L4o9Q/edit, and we will work together to meet your needs. We may use AI-enabled tools to screen and assess applicants against the criteria for this position. This helps our recruiters identify potentially qualified candidates, but it doesn't limit the applications our recruiters may review or consider.
