Job Description
Cox Automotive is deploying enterprise AI capabilities on AWS Quick across the enterprise, helping teams work more effectively in their day-to-day operations. We are looking for a Senior Software Engineer who applies the principles of secure software engineering to the design, development, maintenance, testing, and evaluation of software and cloud infrastructure that supports this initiative. As a senior member of the engineering organization, you will be expected to contribute beyond feature implementation by influencing development practices, mentoring teammates, raising engineering standards, and helping guide technical decision-making across products and services. You’ll regularly balance short-term delivery objectives with long-term maintainability, scalability, and operational excellence. This is early-stage work with executive sponsorship, direct access to AWS technical teams, and the autonomy to shape how the platform is built.
Qualifications
Required Qualifications
- Bachelor’s degree (list any requirements of discipline here) and 4 years’ experience in a related field. The right candidate could also have a different combination, such as a master’s degree and 2 years’ experience; a Ph.D. and up to 1 year of experience; or 16years’ experience in a related field.
- 5+ years of professional software development experience, including designing, building, and operating production systems.
- Strong proficiency in Python, including building APIs, data pipelines, and integrations.
- Hands-on experience with AWS services (Lambda, S3, IAM, API Gateway, CloudWatch, Step Functions, or similar).
- Experience building integrations with third-party APIs and SaaS platforms, including authentication flows (OAuth 2.0, OIDC).
- Experience with Infrastructure as Code (Terraform preferred) and CI/CD pipelines (GitHub Actions preferred).
- Solid understanding of distributed systems concepts: fault tolerance, idempotency, eventual consistency, and graceful degradation.
- Experience designing and enforcing authorization policies in multi-tenant or multi-user systems (row-level security, ABAC, or similar).
- Comfort working in a small, fast-moving team where you own what you build end-to-end.
- Strong communication skills. Able to explain technical decisions clearly and collaborate across teams.
- Applicants must be authorized to work in the United States for any employer without current or future sponsorship.
- Ability to work in the office three days per week.
- Willingness to participate in an on-call rotation for production platform systems.
Preferred Qualifications
- Experience with AI/ML-powered systems, with exposure to emerging patterns such as RAG, knowledge retrieval, or agent-based architectures.
- Experience with Amazon Bedrock, AWS managed AI/ML services, or a comparable enterprise AI platform.
- Familiarity with the Model Context Protocol (MCP) or experience building agent/tool integration layers.
- Experience with Snowflake, semantic views, or similar data platform technologies.
- Background in knowledge graphs, embeddings, vector stores, or enterprise search/retrieval systems.
- Experience building evaluation or testing frameworks for non-deterministic systems (ML model eval, A/B testing infrastructure, or similar).
- Familiarity with cost optimization in cloud-native architectures — FinOps thinking, usage metering, or chargeback systems.
- Experience with data loss prevention, PII detection/redaction, or security controls in data pipelines.
- Experience with event-driven architectures or workflow engines (Step Functions, Temporal).
- Experience building or operating internal developer platforms or developer tooling.
- Experience taking ownership of an inherited codebase and improving it to a well-documented, supportable state.
- Prior work in automotive, media, or another large enterprise with a complex system landscape is an advantage but not required.
