• Work/life balance and a fast-paced and driven environment
• Accountability and pride for your projects

We're looking for a Staff Software Engineer who is equal parts builder and architect—someone who can take a feature from napkin sketch to production deployment and has strong opinions (loosely held) about how modern software should be built. You'll work across the full stack: designing APIs, standing up infrastructure, wiring data pipelines, and shipping microservices that power AI-driven products.

This isn't a role where you'll be handed a spec and asked to implement it. You'll be expected to challenge assumptions, propose better approaches, and move fast with the help of AI coding tools that are core to how we work.

What you'll do:

• Design, build, and own microservices and APIs end-to-end—from data model to deployment pipeline to monitoring.
• Architect and maintain CI/CD pipelines, container orchestration, and infrastructure-as-code across cloud environments (Azure preferred, AWS/GCP a plus).
• Work hands-on with databases (relational and vector), message queues, and search infrastructure—configuring, tuning, and scaling them in production.
• Collaborate with the AI team to integrate ML models and LLM-powered features into production services.
• Champion engineering standards: code review culture, repository structure, testing strategies, and deployment practices.
• Leverage AI-assisted development tools (Copilot, Claude Code, Cursor, etc.) to accelerate delivery—and help the team do the same.
• Operate in Linux environments daily: scripting, debugging, managing services, and keeping systems healthy.

What we're looking for:

The short version: a creative, resourceful engineer who builds real things, has seen what scales and what doesn't, and gets genuinely excited about the new capabilities AI tooling unlocks.

• Languages: Strong Python skills plus meaningful experience in at least one compiled/systems-level language (C#/.NET, C++, Go, Rust, or similar). You know when a scripting language isn't enough.
• Cloud & Infrastructure: Production experience with cloud platforms (Azure, AWS, or GCP). Comfortable with Terraform or Bicep, Kubernetes/AKS, and the general lifecycle of infrastructure-as-code.
• Data & Storage: Hands-on work with SQL databases, Elasticsearch, vector databases (Qdrant, Pinecone, etc.), Kafka or equivalent message brokers. You've set them up, not just queried them.
• Microservices & APIs: Deep experience designing, deploying, and maintaining distributed services. RESTful APIs, gRPC, event-driven patterns—you have opinions about when to use each.
• CI/CD & DevOps: You've built pipelines (Bitbucket Pipelines, GitHub Actions, Azure DevOps, etc.) and care about how repos are structured, how tests run, and how code gets to production safely.
• Linux: Daily-driver comfort. Shell scripting, process management, troubleshooting, system configuration.
• AI Development Tools: Active user of AI coding assistants. You're not just curious—you've integrated them into your workflow and can articulate what they're good (and bad) at.

Bonus points:

• Experience with MLflow, experiment tracking, or ML pipeline tooling.
• Familiarity with Azure Kubernetes Service (AKS) and the Azure ecosystem specifically.
• Background in NLP, RAG architectures, or LLM integration patterns.
• Contributions to open-source projects or a visible portfolio of shipped work.
• Experience in regulated industries (EHS, legal, financial, healthcare).

What you'll get:

• A seat on a small, high-impact AI team building products that matter at global scale.
• Direct access to leadership—short feedback loops, real influence on architecture and direction.
• A culture that treats AI tools as force multipliers, not novelties.
• Competitive compensation, benefits, and flexibility.
• The chance to help shape the engineering culture of a company in a transformative growth phase.

Our tech stack includes Azure/AKS, Terraform, Bitbucket Pipelines, Kafka, Elasticsearch, Qdrant, SQL, and a multi-provider LLM strategy spanning OpenAI, Anthropic, and Google. We build AI microservices in Python and deploy them as containerized services. We use MLflow for experiment tracking and Splunk for observability.

We believe the best engineers are opinionated about their tools and pragmatic about their deadlines. If you have a strong point of view about how a codebase should be organized, how a deployment should work, or why a particular pattern is the right (or wrong) one—we want to hear it.
