Senior Backend Engineer, Platform Services

Blu Juniper is an AI and optimization company building advanced software systems for complex operational environments. Our work spans cloud native platforms, computer vision, natural language processing, data infrastructure, secure collaboration, and mission focused AI/ML applications.

We are looking for a Senior Backend Engineer to help build secure platform services for a computer vision and natural language processing application. This role will focus on backend services that support rules driven workflows, auditability, data modeling, authentication, customer onboarding, and controlled data exchange across the platform.

As a Senior Backend Engineer, you will design and implement backend services that support secure, reliable, and queryable platform capabilities. You will work across microservices, messaging systems, data schemas, APIs, access control, and data sharing workflows.

This role is ideal for an engineer with strong experience in Go, C++, or a similar object oriented or lower level programming language who enjoys building production services, durable data models, and secure system to system integration patterns. Go will be the primary implementation language for this role.

• Design and develop backend services using Go, C++, or a similar object oriented or lower level programming language, with primary implementation in Go.
• Build platform services that support configurable rules, workflow logic, auditability, and secure operational history.
• Develop and maintain data schemas, domain models, event structures, persistence strategies, and data access patterns across backend systems.
• Contribute to shared data exchange capabilities, including controlled data sharing workflows and cross environment integration patterns.
• Design service to service communication patterns, API contracts, event flows, and integration points between distributed services.
• Build backend infrastructure for authentication, authorization, role based access control, and customer onboarding workflows.
• Build event driven systems using Apache Kafka or comparable messaging technologies.
• Partner with product, frontend, AI/ML, Dev Ops, and security stakeholders to translate requirements into well structured backend services.
• Improve system performance, scalability, reliability, and debuggability across production services.
• Participate in design reviews, code reviews, implementation planning, and security reviews.

• 5+ years of professional backend or systems engineering experience.
• Strong proficiency in Go, C++, Java, Rust, or a similar object oriented or lower level programming language.
• Experience designing and operating cloud based architectures on AWS, Azure, GCP, or similar cloud platforms.
• Strong understanding of microservice architecture, service boundaries, API design, inter service communication, and distributed systems tradeoffs.
• Experience with data modeling, schema design, relational and/or non relational databases, and long term data maintainability.
• Experience with Apache Kafka, event driven architectures, message queues, or stream processing systems.
• Experience designing authentication and authorization systems, including role based access control.
• Experience building secure backend services that support structured data exchange, schema driven integrations, or controlled data sharing workflows.
• Strong debugging and performance analysis skills in production backend systems.

• Experience building rules engines, policy engines, workflow engines, audit services, or queryable event history systems.
• Experience with schema registries, protobuf, Avro, JSON Schema, Open Telemetry, Postgre
  
  SQL, Open Search, Elasticsearch, or similar technologies.
• Experience building backend systems for real time collaboration, simulation, spatial platforms, command and control systems, or operational decision support tools.
• Experience with Kubernetes, Docker, infrastructure as code, CI/CD, and modern Dev Ops practices.
• Familiarity with secure software development practices, audit logging, secrets management, and least privilege access design.
