Role description

We're BlueCat—a Great Place to Work for good reason. Our team solves critical network challenges for some of the world's largest organizations. In simple terms, we manage the systems that keep networks running smoothly, securely, and reliably—the backbone infrastructure that powers digital transformation for enterprises globally. Our Intelligent Network Operations platform delivers and enables AI-driven agentic ops at scale, automating and simplifying how companies manage, secure, and optimize their networks.

But what makes us different is how we work: we believe great work happens in an environment where you're trusted, heard, and supported. With teams globally, we're building a workplace culture that values collaboration and integrity as much as innovation. If you're looking to advance your career with a company that invests in its people, this is it.

About the Team

The BlueCat Horizon team powers all BlueCat SaaS products. Our mission is to deliver enterprise-grade software on a reliable, fast, globally distributed, and cost-efficient cloud platform. We are building an AI-first platform, where agentic systems run as core production workloads on
Kubernetes (EKS) and AWS AgentCore.

About the Role

We are looking for a Site Reliability Engineer to help make our AI agent platform production-ready, secure, observable, and scalable. This role focuses on operating, automating, and hardening systems built by development teams, ensuring experimental AI capabilities are reliably delivered as enterprise-grade production services. You will work across platform engineering, infrastructure, and development teams to improve reliability, automation, and delivery speed.

What You’ll Do

  • Operate and scale Kubernetes (EKS) clusters running AI and cloud-native workloads
  • Support productionization of AWS AgentCore-based systems
  • Design, build, and maintain CI/CD pipelines using GitLab CI/CD for applications and platform services
  • Build and improve automated deployment workflows across environments
  • Implement and maintain observability systems (metrics, logs, traces)
  • Define and enforce SRE practices: SLIs, SLOs, alerting, incident response, postmortems
  • Partner with development teams to ensure services are production-ready and operable
  • Participate in on-call rotation and support incident resolution and root cause analysis
  • Build infrastructure using Terraform for repeatable deployments
  • Improve cost efficiency, performance, and reliability of the platform

What You Bring

  • 5+ years of experience in SRE, DevOps, or Platform Engineering
  • Strong hands-on experience with AWS and Kubernetes (EKS)
  • Experience operating or supporting AWS AgentCore or similar AI/agent platforms
  • Strong proficiency in Python for automation
  • Solid understanding of AWS identity and access management (IAM), including SSO/Identity Center, roles, policies, trust relationships, SCPs, and cross-account access patterns
  • Experience with Infrastructure as Code (Terraform preferred)
  • Strong understanding of CI/CD using GitLab CI/CD
  • Ability to quickly onboard into existing AWS environments and operate independently
  • Experience working with on-call and incident management in production systems

Nice to Have

  • Experience with AI/LLM or agent-based systems
  • Running stateful workloads on Kubernetes (PostgreSQL, Redis, etc.)
  • Knowledge of RAG, vector databases, or knowledge systems
  • Multi-region AWS architecture experience
  • Cost optimization and capacity planning experience

If you share our enthusiasm for the future of our company and are eager to contribute to our vibrant workplace, we look forward to receiving your application! Our comprehensive benefits encompass your health, financial well-being, and overall wellness, and we are committed to providing an exceptional work environment, enriching employee programs, and fostering a remarkable company culture. At our core, we champion values such as transparency, curiosity, respect, and above all, the pursuit of enjoyment.

In addition, we offer a range of appealing perks, including:

Role description

About Us
Rho is the modern banking platform built for startups. Open accounts in minutes, issue cards, manage expenses, pay bills, and close the books – all in one connected platform backed by real human support.

Rho is building a modern finance platform that helps businesses manage banking, cards, expenses, bill pay, and accounting workflows in one connected platform.

We're looking for a Senior Software Engineer to help build and scale new financial products from ambiguous opportunity to production-grade systems. This role is for a product-minded backend engineer with strong technical judgment, deep customer curiosity, and the ability to drive complex initiatives across teams, stakeholders, and external partners.

This is a high-ownership role for an engineer who wants to build more than features. You'll help shape new product areas, bring complex financial workflows to life, work directly with cross-functional partners, and grow into broader technical leadership as Rho scales.

You'll work on critical financial workflows and platform capabilities that sit close to how businesses manage money. The work is technically challenging, customer-facing, and often involves regulated systems, operational complexity, and third-party integrations.

What You'll Do

  • Own high-impact projects end-to-end, including our accounting integrations (NetSuite, QuickBooks, Sage Intacct, Xero, Puzzle) that keep customers' books accurate and up to date, from problem definition and technical design through launch, iteration, and operational ownership.
  • Build reliable, scalable backend services that power core accounting and financial workflows, and help us expand into new adjacent product areas as the platform grows.
  • Turn ambiguous product and business problems into simple, durable technical solutions.
  • Develop a deep understanding of our customers' accounting and financial operations pain points, and use that context to make pragmatic product and engineering decisions.
  • Partner closely with Product, Design, Operations, Compliance, and external partners, including accounting software providers and financial data platforms like Plaid and Finicity, to move complex initiatives forward.
  • Make thoughtful technical tradeoffs, with a particular focus on shipping quickly without compromising the reliability of money movement.
  • Raise the engineering bar through clear communication, strong system design, code quality, and mentorship.

What We're Looking For

  • Senior-level experience building production backend systems, APIs, services, or distributed systems.
  • Strong product judgment, customer curiosity, and comfort working through ambiguity.
  • Experience owning projects end-to-end is a plus, but we also value engineers who've built deep expertise in complex systems without owning every stage of the lifecycle.
  • Ability to manage multiple stakeholders and work cross-functionally with non-technical teams.
  • Experience operating in fast-paced, high-growth environments where priorities evolve quickly.
  • A bias toward shipping, learning from users, and continuously improving what you build.
  • Experience with fintech, accounting systems, payroll, payments, banking, compliance-heavy products, or complex integrations is a plus.

Tech we use
Python, Go, GraphQL, PostgreSQL, Docker, Kubernetes, and GCP. Experience with this exact stack is helpful, but not required. We care more about strong engineering fundamentals, product ownership, and the ability to learn quickly.

What We Offer
Our people are our most valuable asset. Base salary may vary depending on relevant experience, skills, geographic location, and business needs.

Benefits

  • Top-notch Private Healthcare Insurance for you and your family members
  • Generous PTO policy
  • Lunch at work
  • Covered costs for parking for onsite staff
  • Learning and development budget
  • Paternity leave
  • Hybrid work environment (with old town Belgrade office)

Diversity is a core value at Rho. We’re passionate about building and sustaining an inclusive and equitable environment for all those involved with our mission, including employees, contractors, candidates, customers and vendors. We believe every member of the Rho community enriches our ability to provide a broad range of ways to understand and engage with the market, identify problems, and drive solutions that align with our mission. We welcome all qualified applications and support each of our Rho’ers with ongoing professional growth opportunities.
