Job summary

Ayr Energy is seeking software engineers to build scalable software platforms spanning distributed systems, data pipelines, APIs, and user interfaces. You’ll enable secure, high‑quality products serving users and operators in critical sectors.

You will work on fault‑tolerant architectures, secure third‑party integrations, LLM orchestration and context management, plus data ingestion and search capabilities. Expect rigorous reviews and strong focus on reliability.

Qualifications

• Bachelor's degree in computer science, Math, Sciences, or a related degree.
• Hands‑on experience with multi‑agent architectures, dynamic model routing, or guardrail/safety systems for LLM‑based agents.
• Experience with enterprise integrations (e.g., Salesforce, Jira, Slack, or internal system APIs).
• Experience working on infrastructure for distributed systems or cloud‑native applications, or building full‑stack apps spanning front‑end, REST APIs, and app servers, or ML training/productionizing.
• Familiarity with observability tooling (Datadog, CloudWatch) and event-driven or streaming architectures (Kafka).
• Proven ability to design, build, and ship production-ready software, ideally around AI/ML systems (LLM orchestration, RAG pipelines, tool-calling).
• Experience with cloud infrastructure and containerised deployments (Docker/Kubernetes).
• Solid understanding of distributed systems, databases, and system design fundamentals.
• Strong algorithmic design skills and first-principles problem-solving.

Responsibilities

• Build large-scale, fault-tolerant distributed systems and data pipelines.
• Architect secure integrations connecting internal systems with third-party platforms.
• Integrate and orchestrate LLMs into product workflows with guardrails and reliability.
• Implement data ingestion pipelines and build secure indexes/search over data.
• Design APIs and user interfaces powering internal search and enterprise apps.
• Instrument systems for observability and drive reliability improvements.
• Code reviews focusing on interface design, quality, and testing strategy.
