About 247 Labs

247 Labs is a technology-driven company building digital products that combine sports, entertainment, and community. We are focused on developing reliable, scalable, and secure platforms that deliver seamless experiences to our users.

As we continue to grow, we are looking for experienced professionals who can strengthen our infrastructure, improve platform reliability, and support the continuous delivery of high-quality technology products.

About the Role

We are looking for a highly experienced Senior Site Reliability Engineer to own and improve the reliability, availability, performance, and resilience of our production platform, including our sportsbook, wallet, and social systems.

In this role, you will be responsible for our cloud infrastructure, deployment pipelines, observability, incident management, infrastructure security, disaster recovery, and operational efficiency.

You will work closely with backend, frontend, and mobile engineering teams to ensure our systems remain stable, secure, scalable, and responsive, particularly during periods of high traffic such as major sporting events and promotional campaigns.

The ideal candidate combines strong cloud infrastructure and platform engineering expertise with a proactive approach to incident prevention, automation, and continuous improvement.

Key Responsibilities

1. Platform Reliability and Availability

Own the reliability, availability, and performance of production services against established service level objectives.
Define and maintain service level indicators (SLIs), service level objectives (SLOs), and error budgets for critical services.
Monitor and report on reliability performance, identifying risks and opportunities for improvement.
Plan infrastructure capacity and scaling to support peak traffic during major sporting events, promotions, and product launches.
Conduct load, failover, and resilience testing and address identified weaknesses.
Design and maintain high-availability and disaster recovery arrangements, including backup strategies, restoration testing, and documented recovery procedures with defined recovery time and recovery point objectives.

2. Infrastructure and Platform Engineering

Build, operate, and maintain cloud infrastructure on AWS, including Amazon EKS/Kubernetes clusters, networking, load balancing, DNS, and content delivery.
Implement and maintain infrastructure as code to ensure consistent, repeatable, and reliable infrastructure provisioning.
Own and improve CI/CD pipelines and deployment tooling, enabling safe and frequent releases through automated testing, staged rollouts, and rapid rollback mechanisms.
Manage and optimise core data and messaging infrastructure, including PostgreSQL, Redis, and Kafka, covering performance, replication, failover, and upgrades in collaboration with backend engineers.
Automate infrastructure provisioning, scaling, patching, certificate management, and routine maintenance to reduce manual work and operational overhead.
Monitor cloud expenditure, optimise resource utilisation, and recommend cost-saving measures.

3. Observability and Incident Management

Build and maintain observability systems covering metrics, logs, distributed tracing, dashboards, and alerting.
Design actionable alerts with appropriate escalation procedures and maintain on-call schedules and escalation paths in collaboration with the Head of IT Operations.
Lead production incident response, coordinating investigation, communication, mitigation, and recovery.
Prioritise incidents affecting critical user and financial workflows, including bet placement, settlement, deposits, and withdrawals.
Conduct blameless post-incident reviews, document root causes, define corrective actions, and track remediation to completion.
Participate in the on-call rota, including evenings, weekends, and major sporting events, as reasonably required.
Serve as a senior escalation point for complex production incidents.

4. Security and Compliance Support

Implement and maintain infrastructure security controls, including network segmentation, access management, secrets management, encryption, patching, and system hardening.
Support applicable regulatory and licensing obligations through infrastructure reliability, incident reporting, data residency, data retention, and technical audit evidence.
Assist with security, fraud, and data protection investigations by providing relevant logs and infrastructure expertise.
Monitor the reliability of third-party dependencies, including data feed providers, payment providers, and cloud services, and maintain documented failure and recovery procedures.

5. Engineering Collaboration and Standards

Collaborate with backend, frontend, and mobile engineering teams to improve service operability, production readiness, deployment processes, and performance.
Establish and promote reliability standards, including runbooks, health checks, graceful degradation, and load shedding.
Mentor engineers on operational excellence, reliability practices, and incident management.
Maintain clear technical documentation and contribute to knowledge-sharing initiatives.
Communicate operational risks and recommend infrastructure improvements, tooling, and roadmap priorities to the Head of IT Operations.

6. General Responsibilities

Attend team meetings and company events as required.
Comply with company policies relating to confidentiality, information security, data protection, and responsible gambling.
Maintain the confidentiality of company infrastructure, security arrangements, and commercial information.
Perform other duties reasonably consistent with the role.

Requirements

Demonstrable experience in Site Reliability Engineering, DevOps, Platform Engineering, Cloud Infrastructure, or a closely related field.
Strong hands-on experience with AWS and container orchestration using Kubernetes/Amazon EKS.
Experience managing cloud networking, load balancing, DNS, content delivery, and infrastructure as code.
Proven experience designing, maintaining, and troubleshooting CI/CD pipelines and deployment automation.
Strong knowledge of observability practices, including metrics, logging, tracing, dashboards, alerting, and incident management.
Experience managing production databases and messaging systems such as PostgreSQL, Redis, and Kafka.
Understanding of high availability, disaster recovery, backup and restoration testing, capacity planning, and performance optimisation.
Experience with infrastructure security, access controls, secrets management, encryption, patching, and system hardening.
Ability to lead production incident response, conduct root-cause analysis, and implement corrective actions.
Strong troubleshooting, analytical, communication, and problem-solving skills.
Ability to collaborate effectively across engineering and operations teams.
Willingness to participate in on-call support, including evenings, weekends, and major sporting events when reasonably required.
