Empowered by cutting-edge tools and methodologies, you will have a unique opportunity to accelerate your career alongside a world-class team, innovating at the speed of data to do the hard, right thing for our customers.

About the Position:

As a Business Systems Engineer at Qumulo in Cork, you will be a foundational member of the team that builds and operates the systems powering Qumulo's revenue and customer infrastructure, such as consumption metering, cloud marketplace integration, and where our customers see and manage their usage. You will own production code that handles real money and customer trust, building cloud-native, serverless integrations across AWS and Azure, and partnering closely with our Business Systems and Sales Operations teams to translate business needs into reliable, well-engineered software.

This is a true ownership role: you will be the technical lead and risk steward for a critical revenue pipeline, with on-call responsibilities and the autonomy to drive engineering best practices into the codebase you inherit. At Qumulo, you are part of a community where every individual has a voice, empowered with the charter to design and build features that deliver clear value to our customers.

Responsibilities:

• Design, build, and operate the consumption metering pipelines that ingest customer usage and submit rated usage to AWS, Azure, and Google Cloud marketplaces.
• Develop and maintain serverless logic across AWS (Lambda, EventBridge, SNS, SQS) and Azure (Functions, Storage, Application Insights), with modern Python at the core.
• Act as technical owner of the metering codebase: drive code review, testing, CI/CD, and infrastructure-as-code standards, and lead rebuilds where structurally needed.
• Participate in an on-call rotation for the metering and submission pipeline. Submission to the marketplace is part of the product, and it cannot go down.
• Identify and mitigate risks across the system, from operational gaps to architectural weaknesses.
• Partner with the Nexus product team to ship customer-facing features: live balances, accurate usage, burn-rate forecasting, and what-if scenarios.
• Work directly with Business Systems, Sales Operations, Finance, and Customer Success to translate non-technical requirements into shipped software.
• Lead the technical relationship with external SaaS partners and transition critical systems in-house when reliability and velocity call for it.

Qualifications:

• 3+ years of software engineering experience ideally including integrations with billing platforms, cloud marketplaces, or payment providers.
• Deep, hands-on Python expertise: modern module development, library management, scripting, and tooling.
• Production experience with AWS serverless and event-driven services (Lambda, EventBridge, SNS, SQS), and Azure serverless and storage services (Functions, Storage, Application Insights).
• Strong experience integrating with REST APIs and external SDKs in production. Familiarity with microservice patterns, particularly for AI integrations.
• Production reliability mindset: you've been on-call for systems that mattered and understand alerting, idempotency, retries, and observability. Willingness to join an on-call rotation is required.
• Strong written and verbal communication skills, with a track record of working directly with non-technical stakeholders.
• Hands-on experience using modern AI developer tools to ship faster without compromising code quality or security.
• A Bachelor's or Master's in Computer Science, Computer Engineering, or related field

Further Details:

• Competitive salary and benefits package, including equity, pension, and healthcare
• Flexible working arrangements, with 3 days onsite and 2 remote
• Reimbursement for home phone and internet
