Remote Senior Backend Engineer — Data & Agentic Context

Fetch; Northern (KY); Hybrid; USD 190,000 - 224,000; Full time

Job summary

Fetch is seeking a Senior Backend Engineer II to build the data and context foundation for our agentic platform. You will design and operate backend services, APIs, data pipelines, and storage systems to provide trusted context with latency, quality, security, and cost considerations.

Work with cross-functional teams including agent, machine learning, data, security, and product teams to own systems from ingestion to serving.

Qualifications

• 8+ years of professional software engineering experience, including ownership of production backend or distributed systems at meaningful scale.
• Strong programming skills in Go, Python, Java, or Rust, plus proficiency in SQL and data modeling.
• Experience designing and operating APIs, asynchronous workflows, and data-intensive systems with demanding reliability, scalability, latency, and data-quality requirements.
• Experience with modern data infrastructure, including streaming or messaging systems, batch processing, operational databases, and cloud-based data platforms.
• Sound technical judgment regarding data consistency, schema evolution, privacy and access control, failure handling, performance, and cost.
• Experience with AWS, Infrastructure as Code tools (Terraform, CloudFormation), CI/CD, and modern software delivery practices.
• Ability to lead ambiguous technical problems from architecture through adoption, delivering incrementally and improving systems based on evidence.
• Strong communication and collaboration skills; mentor engineers and align cross-functional partners.
• A bachelor’s or advanced degree in Computer Science, Engineering, Data Science, Mathematics, or related field—or equivalent practical experience.

Responsibilities

• Design, build, and operate scalable backend services and APIs that ingest, transform, retrieve, and serve context to agents and product applications.
• Own batch and real-time data flows, including event ingestion, transformation, indexing, storage, and low-latency serving.
• Develop reusable capabilities for context assembly, memory and state interfaces, provenance, authorization-aware retrieval, and evaluation signals.
• Define data models, schemas, and contracts; implement validation, lineage, freshness checks, and observability as systems evolve.
• Select storage and retrieval patterns across databases, data warehouses and lakes, search systems, caches, and graph or vector technologies.
• Establish SLIs/SLOs, monitor latency and correctness, plan capacity, manage costs, and design failure/recovery paths.
• Translate ambiguous context needs into durable platform abstractions and lead technical designs through adoption.
• Improve engineering velocity through SDKs, tools, deployment patterns, and paved paths.
• Mentor engineers and raise the bar for backend architecture and data quality.
