- Take ownership of complex features from design through to production and ongoing operation
- Drive architectural discussions and contribute to long-term technical strategy
- Collaborate with cross-functional teams to deliver secure, privacy-compliant features aligned with regulations (e.g., GDPR, BIPA, CCPA)
- Mentor engineers through code reviews, pairing, and technical guidance
- Improve system reliability, scalability, observability, and performance
- Partner with product and UX teams to deliver high-quality, user-centric experiences
- Champion secure coding practices and contribute to identity and cryptographic systems
- Identify and implement improvements to engineering practices, tools, and workflows
Key Projects You’ll Support
- Leading enhancements across identity verification and authentication products
- Driving the evolution of the Signals platform architecture
- Designing and maintaining SDKs and APIs for a consistent developer experience
- Scaling third-party integrations
- Integrating advanced security and identity features into Entrust’s identity platform
What We’re Looking For

- Strong proficiency in React/TypeScript and at least one backend language (Python, Kotlin, or Ruby)
- Proven experience designing and building distributed systems and scalable architectures
- Experience building and operating APIs and microservices in cloud environments (AWS, Azure, GCP)
- Familiarity with containerization and orchestration (Docker, Kubernetes)
- Strong understanding of system design, performance, and reliability trade-offs
- Deep knowledge of software security principles and privacy-by-design approaches
- Experience working in agile environments with CI/CD practices
- Strong communication skills with the ability to influence technical decisions
- Experience mentoring engineers and contributing to team growth
Preferred Qualifications
- Knowledge of identity protocols (OAuth 2.0, SAML, OpenID Connect)
- Experience with frameworks such as Spring Boot or Ruby on Rails
- Understanding of privacy regulations and their technical implications
- Experience building secure SDKs or working on developer platforms
Why Join Entrust?
- Work on high-impact identity and security systems used globally
- Play a key role in driving geo-expansion and regulatory-compliant products
