Senior integration engineer

Weave dozens of government systems and decades of legacy into one seamless, event driven experience, with no dropped messages and no visible seams.

At RQMNA, we connect and modernize the platforms that governments and large enterprises depend on, sovereign, secure, and built for national scale.

We are hiring a Senior Integration Engineer, on site in Muscat, to make dozens of systems behave as one.

What you'll do

Design the integration and event backbone that makes dozens of systems behave as one.

Key Responsibilities

Design and build the integration layer across an enterprise service bus, API gateways, and an event streaming backbone

Architect event driven integration: publish and subscribe, streaming, and change data capture for real time data movement

Design API first contracts, with versioning, schema governance, and a developer portal

Connect modern services and decades of legacy and government systems, cleanly and securely

Engineer for resilience: idempotency, retries, dead letter handling, backpressure, and guaranteed delivery

Implement B2 B and EDI exchanges for cross entity document and data flows

Build in security, observability, and distributed tracing so every message is auditable end to end

Set integration standards and reusable patterns, and mentor engineers on them

What makes you a fit

You have built enterprise integrations that moved real volume between real systems, in production

You are fluent across an ESB, API management, and event streaming such as Kafka and web Methods

You think event first and asynchronous, and you know when synchronous is the wrong choice

You design for failure: idempotency, retries, dead letters, and exactly once where it matters

You speak both modern API and legacy protocol, and you make them agree

You hold a Bachelor's or higher in Computer Science, Software Engineering, or a related field

You document clearly and leave patterns others reuse

Bonus points for government or large enterprise integration landscapes

Fluent English required; Arabic is a valuable advantage

If making systems agree is your kind of puzzle, we have the hardest one. Apply.
