Senior Software Engineer - Authorisation

Are you an enthusiastic Software Engineer who’s ready to embark on new challenges and take your career to new heights?

Join our team at Enigma in Helsinki as a Senior Software Engineer​, and play a pivotal role in building our secure

and scalable Identity and Access Management system.

As part

of the Infrastructure Group at Smartly, Enigma builds and operates the systems that govern access across our SaaS platform. The

team focuses primarily on authorisation​: determining what users, teams, services and customers are allowed to

access, and enforcing those decisions reliably across a complex, distributed product.

We solve challenging problems

around:

• Policy design, evaluation and

enforcement.

• Scalable access-control

systems for multi-tenant SaaS.

• Supporting

identity and authentication signals where they are required for access decisions.

• Billing operations and the

Billing Engine.

Authentication and login technologies, including Single Sign-On (SSO), SAML and OpenID, are

relevant to the wider domain but are not the primary focus of this position. The main focus is building robust authorisation

capabilities on top of identity and authentication signals.

We develop and maintain microservices built mainly using

TypeScript, NodeJS, Koa, KnexJS, Postgres and Kafka​, running in our Kubernetes​ clusters. This

role is focused on the authorisation domain​ within the Enigma team.
