You'll build reliable, well-tested and well-documented services, own them from implementation to production, and work with external system vendors on integrations. This is a fully remote position within Portugal, with occasional in-person team days during the year.

• Develop and maintain integrations with external systems, including webhooks and third-party APIs.
• Build event-driven services on AWS.
• Implement features in our core data layer, including identity resolution and reconciliation across source systems.
• Write automated tests and take part in code reviews.
• Implement monitoring, logging and alerting for the services you build.
• Support production services as part of a shared team rotation.
• Apply access control and data protection practices when handling patient data.
• Work with external system vendors on technical integration requirements.
• Document services, data flows and operational procedures.

Requirements

• 3+ years of professional experience building backend services with Node.js and TypeScript in production environments.
• Hands-on experience with AWS services such as Lambda, API Gateway, SQS or SNS.
• Experience with a relational database, preferably PostgreSQL, including schema design and migrations.
• Experience integrating third-party APIs or webhooks, including handling retries, failures and duplicate messages.
• Good understanding of API security fundamentals: authentication, request signing and validation of untrusted input.
• Experience writing automated tests (unit and integration).
• Effective use of AI-assisted development tools, with the ability to review and take responsibility for the code they produce.
• Fluency in Portuguese and English.

Preferred Skills

• Experience with infrastructure as code (CDK, Terraform or equivalent).
• Experience with event-driven patterns such as queues, idempotent consumers and dead-letter queues.
• Background in healthcare or another regulated environment with GDPR obligations.
• Familiarity with HubSpot.
• Clear communication, including with non-technical stakeholders and external vendors.
• Curiosity and willingness to learn, and the ability to take ownership of well-defined problems.

Why you should join Insparya

• Join an international group with a strong focus on innovation, technology, and healthcare excellence.
• Work on large-scale platforms and systems that directly support patient care and business operations across multiple countries.
• Be part of a collaborative and highly skilled technology team with opportunities for professional growth and career development.
