We constantly innovate our platform and capabilities to meet tomorrow’s challenges, anticipate the risks our clients encounter, and design advanced solutions to help our clients achieve transformational business outcomes.

We value intellectual curiosity, proactive ownership, and collaboration with colleagues, and we empower you to meaningfully contribute from day one and accelerate your professional development.

About the Role and the Team

We are looking for an intelligent, resourceful, and highly skilled Senior Site Reliability Engineer (SRE) to join our Platform Site Reliability Engineering (PSRE) team. This team plays a critical role in ensuring the stability, reliability, and availability of mission-critical production applications on the Arcesium platform.

The PSRE team is responsible for:

Observability, monitoring, logging, and tracing to proactively detect and prevent issues.

Building tools and infrastructure that enhance system stability and resilience.

Troubleshooting live production issues with a deep focus on rapid incident resolution.

Governing, declaring, managing, and recovering from platform-wide incidents to minimize downtime and business impact.

As an SRE in this high-impact team, you will work under tight timelines in a high-pressure environment, where every second counts in resolving critical production incidents. This means you must be quick-thinking, highly analytical, and proactive in preventing and resolving disruptions.

What You Will Do:

Incident Management: Serve as a primary contact and leader for incidents and critical issues impacting our platform during NY business hours. Take ownership of incidents, drive effective communication, and facilitate swift resolution by collaborating with relevant engineering teams.

Proactive Monitoring & Analysis: Continuously monitor the health and performance of our applications and infrastructure. Analyze trends, identify potential risks, and proactively implement measures to prevent incidents and improve overall system reliability.

Troubleshooting & Problem Solving: Troubleshoot complex technical issues across various layers of the stack (application, infrastructure, network). Utilize your analytical skills and technical expertise to identify root causes and implement effective solutions.

Collaboration & Communication: Work closely with engineering, development, and operations teams to ensure seamless collaboration during incident response and in proactive reliability initiatives. Communicate effectively with stakeholders at all levels, providing clear and concise updates on incidents and system status.

Automation & Optimization: Identify opportunities to automate tasks, improve operational efficiency, and enhance the resilience of our systems. Develop tools and scripts as needed to streamline processes and reduce manual intervention.

Continuous Improvement: Contribute to the ongoing development and improvement of our SRE practices, tools, and processes. Share your knowledge and expertise with the team to foster a culture of learning and growth.

What we’re looking for:

Up to 5 years of experience in a Site Reliability Engineering (SRE), DevOps, or Production Engineering role, with a deep understanding of SRE principles and best practices.
Incident management expertise, including triaging, escalation, and resolution of high-severity outages.
Proficiency in at least one coding language (Python or Java) for automation and debugging.
Hands-on experience in Kubernetes (K8s) for managing and orchestrating containerized applications.
Cloud experience (AWS preferred) with exposure to key services like EC2, S3, Lambda, and CloudWatch.
Excellent communication skills to articulate technical challenges and solutions effectively.
Strong troubleshooting and problem-solving skills, with experience diagnosing complex production issues.
Ability to stay calm under pressure, multitask, and prioritize effectively in fast-moving environments.
Fluency in English (spoken and written) is required.
Must have the legal right to work in the country.

Nice-to-Have Skills:

Experience with Terraform or CloudFormation for infrastructure-as-code.

Experience with monitoring tools (e.g., Datadog, Prometheus, Grafana)

Familiarity with web application architectures and best practices.

Exposure to CI/CD pipelines and DevOps workflows.
