Essence of the Role

The Shield team is building the next generation of KYC and customer trust tools within Sinch’s platform domain. Our mission is to be the go-to team for customer trust evaluation across the company.

We build APIs and event-driven services that support product teams and internal stakeholders. We are responsible for maintaining trusted customer records and making that data securely available across Sinch.

As our new Software Engineer, you will

• Play a key role in designing, building, testing, and operating services used across Sinch

• Enforce security best practices, including authentication and authorization

• Contribute to tools, documentation, and internal developer support that make it easier for teams to build on our platform

• Own features throughout the full development lifecycle — from ideation to production — in a “you build it, you run it” environment

• Collaborate within a cross-functional team (engineering, product, and design) to deliver platform solutions for the wider Sinch organization

Requirements

You are a product-minded engineer who is passionate about building robust, scalable, and secure infrastructure that empowers developers and delights customers. You have a strong sense of ownership and thrive in a collaborative, fast-paced environment where your work has meaningful impact.

You should have:

• Professional experience building and operating production backend systems

• Strong interest in system design, high availability, and distributed systems

• Solid programming experience with technologies such as Java, Kotlin, Spring, MySQL/PostgreSQL, and Kafka

• Hands-on experience with container technologies (Docker, Kubernetes)

• Experience with performance tuning and observability tools (e.g., Grafana, Datadog)

It’s a plus if you also have:

• Experience working at a product-focused company, with an understanding of how engineering drives customer experience

• Frontend experience (e.g., TypeScript, React) and comfort working full-stack

• Experience with performance, load, and reliability testing
