Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block.
The Role
As a member of the SRE team, you will proactively and reactively improve the reliability of Block's platform and critical infrastructure. You are metrics‐driven, systems‐oriented, and focused on building distributed platforms that enable safe, scalable product development.
You will leverage and continuously improve AI‐driven tooling and automation to enhance observability, accelerate incident detection and response, and reduce operational toil. This includes applying AI to incident analysis, alert tuning, and operational workflows.
You will participate in primary platform oncall (12 hours per day, one week every few weeks, depending on team size), supporting Block's most critical (Tier 0) services. In this role, you will lead incident command, coordinate mitigation, and drive effective escalation during high‐severity events.
You Will
* Build and extend platforms to improve system reliability
* Work on team goals that encompass reliability for the entire company
* Standardize reliability tools across multiple platforms and organizations
* Triage, coordinate, and lead stabilization of sev 0–1 incidents
* Serve as primary oncall, maintaining structured escalation paths and exercising leadership escalation
* Drive platform‐wide reliability improvements, shared operational tooling, and deploy‐safety patterns
* Use AI‐driven systems to improve signal detection, reduce noise, and accelerate root cause analysis
* Design and implement safe deployment patterns (progressive delivery, automated rollback, guardrails)
You Have
* Drive to root cause systems with many moving parts and take the necessary steps to fix them
* Demonstrated technical initiative and leadership on previous projects, especially those with a backend/platform focus
* Familiarity with AI‐driven tooling for observability, incident analysis, or automation

* Experience running production oncall for high‐availability systems
* Strong incident management skills — structured triage, mitigation under pressure, blameless post‐mortems
* Fluency with CI/CD pipelines, progressive rollout strategies, and rollback automation
* Monitoring & observability expertise — building/tuning alerts for uptime, error rates, latency regression, and resource exhaustion
* Ability to create and maintain evidence‐based maturity assessments using trailing 90‐day data windows.
* Comfort with vendor/dependency management — maintaining validated escalation contacts reachable within 5 minutes.
* Boundless curiosity, autonomy, and a strong sense of accountability
* A strong desire to perform and grow as an engineer
* 5+ years of software development experience
