Why this role matters:

We are seeking a Backend Engineer (Engineer III) for our Jumper AI / Conversational Commerce platform team to design and build backend systems that power a Journey Builder, a workflow orchestration engine used to model and execute complex, event-driven customer journeys. This role focuses on implementing advanced algorithms, orchestration logic, and distributed execution models that support branching, state management, retries, and long-running workflows. You will work on microservices built with Go (programming language) that coordinate events across multiple systems while meeting performance, reliability, and correctness requirements.

Your key responsibilities:

• Design and implement backend services using Go (programming language) and modern Go API frameworks such as Gin, Echo, or Fiber within a distributed microservices architecture.

• Build and operate core components of a Journey Builder/workflow orchestration platform.

• Develop execution models for stateful, long-running workflows, including branching, retries, fan-out, joins, and recovery.

• Design and implement routing, decision, and event-correlation algorithms with strong correctness and idempotency guarantees.

• Build event-driven and asynchronous pipelines using systems such as Apache Kafka, Google Pub-sub, Amazon Simple Queue Service, or Amazon Simple Notification Service.

• Design and manage workflow state, execution history, and intermediate data using storage solutions such as PostgreSQL, Amazon DynamoDB, and Redis.

• Own backend services end-to-end, including deployment, monitoring, on-call support, and production incident resolution on Amazon Web Services.

• Embed AI assisted engineering into daily practice to accelerate delivery and enhance outcomes

• Proactively adopt emerging AI capabilities to improve workflows and shares best practices with the team

What you'll bring

• 5+ years of backend engineering experience building production-grade systems.

• Strong proficiency in Golang and experience building REST APIs and microservices.

• Solid understanding of distributed systems, microservices architecture, and event-driven design.

• Experience building workflow engines, orchestration layers, rule engines, or state machines.

• Hands-on experience with asynchronous processing, retries, deduplication, and failure recovery.

• Strong data modeling skills using SQL and NoSQL databases such as PostgreSQL, DynamoDB, or Redis.

• Experience working with cloud infrastructure (GCP/AWS) and modern development practices, including CI/CD and containerization.

Experience we consider a plus:

• Experience building customer journey orchestration, campaign automation, or messaging platforms.

• Exposure to state machines, DAG execution engines, or workflow orchestration frameworks.

• Experience designing high-scale, low-latency distributed systems and optimizing workflow execution performance.

How you’ll benefit:

• Attractive Discretionary Time Off

• Private Medical Insurance with optional dependent coverage

• Educational Assistance Reimbursement Program

• Opportunities for reimbursement for conferences, trainings, and other personal development events

• Maternity and Paternity Leave

• Ask recruiter for country specific information
