Descripción del empleo

Random Walk has delivered best in class alternative data insights focused on consumer email behavior for over a decade.

We’re looking for a senior backend engineer to help design and operate high-volume, distributed backend systems. This role focuses on data ingestion, asynchronous processing, and scalable service design in a production environment with real-world constraints.

You’ll be expected to own critical backend components end-to-end and make pragmatic decisions around performance, reliability, and cost.

Core skills & how you’ll use them

• Backend programming (Go, Python) Build and maintain high-throughput services and background workers.


• Asynchronous & event-driven systems Design pipelines using queues and workers to process large volumes of data reliably.


• Message queues & streaming systems (Kafka, Pub/Sub, SQS, RabbitMQ, Redis, etc.) Handle fan-out processing, retries, backpressure, and fault isolation.


• Third-party API integrations Build resilient integrations that handle rate limits, partial failures, retries, and schema changes.


• OAuth2 & secure access patterns Implement token-based access flows and manage long-lived integrations safely.


• Structured & unstructured data processing Normalize, parse, and extract meaningful data from inconsistent inputs (HTML, text, metadata).


• Distributed system reliability Implement idempotency, deduplication, observability, and graceful failure handling.


• Cloud & containerized environments Deploy and operate services using Docker and cloud infrastructure (Kubernetes experience is a plus).


• ML inference or classification pipelines Integrate or operate inference/classification workflows (rules-based, ML-based, or hybrid) in production systems


• Design and operate pipelines that ingest and process high volumes of data using event-driven and asynchronous architectures.
