Our team creates and supports detection and other security-relevant tooling that is deployed across our environment. As a Lead Engineer, you will use your expertise to address complex problems and ensure continuous improvements for Target’s defensive capabilities. We are looking for an experienced Backend or Fullstack Engineer to drive the evolution of our Go-based detection platform. In this role, you will build and maintain high-throughput consumer pipelines (YARA/YARA-X), secure secrets management workflows (Vault/KMS), and resilient asynchronous orchestration. You will work at the intersection of backend systems, cryptography and data engineering to deliver scalable security solutions at scale!

Requirements

• 4 year degree or equivalent experience.
• 7+ years of software development experience in Go services, modules, and tests with deep domain knowledge in package-specific configuration and deployment.
• Experience in building highly scalable distributed systems
• Ability to design new testing methods and resolve complex technical issues with minimal assistance.
• 3+ years of experience designing/operating Vault integrations and KMS-style key handling, including secure key lifecycles.
• Practical experience with YARA/YARA‑X or similar pattern engines.
• 3+ years Postgres experience (migrations, indexing, tuning).
• Experience with Kafka stream-processing patterns; comfort with Benthos or equivalent.
• Proficiency with Docker/Docker Compose, Dockerfile optimization and Makefile-driven workflows.
• Working knowledge of OpenTelemetry, distributed tracing, and metrics instrumentation.
• Deep knowledge of pattern-matching algorithm performance trade-offs.
• Delivers high-performance, scalable, and secure solutions with broad impact (high throughput/low latency).
• Understands the downstream impact of work on the team and guests.
• Stays current with evolving technologies via formal training and self-directed education.

Nice To Haves

• Familiarity with string-search algorithms (e.g., Aho–Corasick) is a plus.

Responsibilities

• Platform Development: Maintain and extend a high-performance detection platform comprising consumer rule processors (YARA/YARA‑X), event producers, APIs, and asynchronous workflows.
• Secrets Management: Own the design and operation of Vault-backed secrets flows and encryption proxies (KMS); review and harden key usage patterns and remediation lifecycles.
• Data & Storage: Implement and optimize Postgres schema migrations and query performance. Integrate search capabilities (Solr/Lucene) when required.
• Reliability & Scale: Troubleshoot high-throughput pipelines (Kafka/Benthos), ensuring idempotency, backpressure handling, and effective instrumentation (traces/metrics).
• Engineering Excellence: Improve test coverage (unit, integration, golden tests), refine CI/CD pipelines (golangci-lint), and optimize Docker-based developer workflows.
