Our people. It’s the curiosity, dedication, and innovation that drive our success and help us anticipate the future.

Senior Fullstack Software Engineer (Signals Team)

Location: London, UK / Lisbon, Portugal (Hybrid / Remote options available)
Department: Engineering
Reports To: Engineering Manager
Job Type: Full-Time

About the Role

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

What We’re Looking For

Required Qualifications

5+ years of professional experience in fullstack or software engineering

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

Influence architecture and technical direction within the Signals platform

Collaborate in a supportive, inclusive, and high-performing engineering culture

Flexible working (hybrid/remote) to support work-life balance

Strong investment in career growth, leadership, and learning
