About the Job

Requirements

  • At least 7 years of experience in site reliability engineering, DevOps, or platform engineering, running multi-tenant software-as-a-service systems in production.
  • Strong AWS experience and experience with Terraform at scale, Spacelift, Terraform Cloud, Atlantis, or similar tools.
  • Experience building service-level-objective-based alerting and observability with Datadog or similar tools, ideally with OpenTelemetry.
  • A track record of leading incidents calmly and turning post-incident reviews into lasting fixes.
  • Hands-on PostgreSQL operations experience, including backups, point-in-time recovery, performance tuning, and upgrades.
  • Production-quality coding skills for automation and tooling.
  • A least-privilege mindset and a disciplined approach to using artificial intelligence tools.

Responsibilities

  • Define service-level objectives and error budgets for agent APIs, streaming, and background work, including quality signals such as task success, tool-call failures, and evaluation regressions, and alert on what matters to customers.
  • Own the platform's AWS infrastructure, including ECS on Fargate, Aurora PostgreSQL, Redis, and Amazon Bedrock, as Terraform delivered through Spacelift.
  • Build observability in Datadog and Coralogix with OpenTelemetry, including AI signals such as token usage, provider latency, and cost per task.
  • Make data stores resilient with tested backups and restores, failover, defined disaster recovery targets (RTO/RPO), and safe migrations.
  • Build resilience into the model layer through provider failover, quota and rate-limit management, and safe rollout and rollback of model and prompt changes.
  • Protect the platform under multi-tenant load with per-tenant quotas, isolation, and circuit breakers that stop runaway agents and spending.
  • Partner with Security on operational controls for AI risks, including prompt injection, excessive agent permissions, and unbounded consumption, addressing the OWASP Top 10 for LLM Applications.
  • Set guardrails for AI agents working on infrastructure, specifying what they can change, which actions require human approval, and how every action is audited.
  • Work with Security and Privacy to keep model inference and customer data in appropriate regions for customers in Australia, New Zealand, the United States, the United Kingdom, and the European Union.
  • Lead incident response and blameless reviews, participate in on-call, and run game days for significant failure scenarios.
  • Make deployments safe by default and provide product teams with simple, standard ways to run agent workloads.
  • Track and reduce cloud and model spending.

Desired Qualifications

  • Experience running large language model or AI workloads in production, or a genuine interest in learning how they fail differently from traditional services.
  • Use of AI agents to automate operational work, such as incident triage, runbooks, or infrastructure-code review, and a clear understanding of where human review remains important.
  • Experience in regulated environments such as SOC 2 or PCI DSS.
  • Experience with Amazon Bedrock quotas and inference profiles, policy as code, large language model evaluation, AI security tooling, or multi-region data-residency requirements.

About the Company

Xplor

Vertical SaaS with embedded payments

Xplor provides a global platform that combines software-as-a-service with embedded payments and tools for small and mid-sized businesses in education, fitness, field services, and personal services. It works by pairing vertical-specific management software with an integrated payments system called Xplor Pay, allowing businesses to run operations and take payments in one place. What sets Xplor apart is its focus on many different verticals, built into one brand through acquisitions, creating a single ecosystem rather than separate software or payment products. Its goal is to help SMBs grow recurring revenue and process more payments across many countries, aiming to serve about 130,000+ businesses and handle tens of billions in payments.
