Senior Fullstack Software Engineer

 

Description:


We are looking for a Senior Fullstack Software Engineer to join our Signals Team, contributing to the development of secure, scalable applications that support digital identity and authentication services.

You will work across the stack—from intuitive frontend interfaces to robust backend systems—collaborating with engineers, product managers, and designers to deliver impactful solutions. This role is ideal for engineers who take ownership of complex features end-to-end, influence technical direction, and help raise the engineering bar across the team.

Signals Team Mission

Accelerating global expansion with locally trusted identity verification solutions

The Signals team builds and maintains critical identity verification capabilities that enable secure onboarding and regulatory compliance worldwide, including:
 

  • Proof of Address (PoA)
  • AML (Anti-Money Laundering) checks
  • eKYC database integrations
  • eID and digital identity integrations
     

These systems power trusted identity flows across multiple geographies and regulatory environments.

What You’ll Do
 

  • Lead the design, build, and evolution of fullstack applications using React (TypeScript), Kotlin, Python, and Ruby
  • Architect and develop scalable APIs and microservices deployed on AWS, Azure, or GCP
  • 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
