Aimprosoft, a fast-growing IT company, is expanding its cooperation with a large European retail enterprise operating across multiple countries. We are looking for a Senior Integration / API Engineer to join a strategic CRM and integration landscape centered around Salesforce Sales Cloud, Kafka, and an existing MuleSoft integration layer.
About the project & role:
You will join an active enterprise ecosystem where Salesforce acts as the core B2B CRM, integrated with multiple surrounding systems across the organization.
Currently, Salesforce communicates via MuleSoft, which in turn connects to Kafka and other internal systems. At the same time, there is a strategic direction to simplify and gradually move away from MuleSoft, potentially enabling direct Salesforce ↔ Kafka communication in the future.
As the sole integration specialist on the project, you will: * Maintain and extend existing integrations * Design and implement new data flows * Work closely with multiple development teams to understand information needs * Evaluate integration approaches and challenge MuleSoft usage when it is not the optimal solution
This role requires strong independence, architectural thinking, and broad integration experience, not just MuleSoft configuration skills.
What We Need From You: * 5+ years of experience as an Integration / API Engineer * English level — Upper-Intermediate (B2) or higher. * Hands-on experience with MuleSoft Anypoint Platform (design, development, maintenance) * Strong experience with API design and integration patterns (REST, event-driven architectures) * Practical experience with Kafka or other message brokers * Solid understanding of the Salesforce object model and Salesforce integration patterns * Experience integrating Salesforce with external systems (ERP, PIM, analytics, internal platforms) * Ability to work independently and derive integration requirements without detailed upfront specs * Capability to design, document, and explain integration solutions to technical and non-technical stakeholders * Readiness to challenge existing architecture and propose better or simpler alternatives * Ensure a single source of truth for accounts and partner data. * Ability to analyze requirements and propose technical solutions * Participate in discovery and planning sessions; challenge requirements when needed. * Experience collaborating with architects, business analysts, and PMs * Ensure platform security, scalability, and performance. * Ability to evaluate requirements and guide the business toward scalable solutions. * Strong problem-solving and communication skills
Nice to have: * Experience designing Salesforce ↔ Kafka direct integrations * MuleSoft certifications or Salesforce integration certifications * Background as an API / Integration Architect * Previous experience in Retail, E-Commerce, or Construction B2B domains. * German language understanding is a plus. * Education: A Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field is preferred (or equivalent real-world experience).
What We Offer: * A competitive salary that appreciates your skills and experience * Long-term collaboration with a large-scale European enterprise. * Opportunity to define architectural standards and influence product direction. * Cozy atmosphere and modern approaches. We have neither bureaucracy nor strict management nor “working under pressure” conditions * Opportunity to implement your ideas, tools, and approaches. We are open to changes and suggestions aimed at improvement * Work on a strategic, large-scale international project with high visibility. * Remote-friendly culture with strong team collaboration.
