We’re looking for our next Senior Principal Site Reliability Engineer. Could It Be You?

The Senior Principal Site Reliability Engineer is directly responsible for the stability, resiliency, and scalability of business-critical brokerage back-end applications running across a hybrid on-premises and cloud architecture.

This individual drives reliability engineering practices - SLOs/SLIs, observability, incident response, and capacity planning - while also making hands-on, code contributions directly into multiple applications across different technology stacks using an inner-source model. The role blends deep technical execution with cross-team influence: this person is expected to identify systemic reliability risks, fix them where they appear, and raise the operational bar for every team they touch.

This position is a strong fit for a hands-on senior principal engineer who is energized by fixing production reliability at the source, is comfortable navigating multiple codebases and cloud/on-prem environments, and wants to have an outsized impact on the resiliency of a regulated, high-availability brokerage platform.

Need more details? Keep reading…

Application Stability, Reliability & Growth

Own the end-to-end reliability posture of critical brokerage back-end applications, driving measurable improvements in availability, latency, and error budgets across on-premises and cloud environments.
Define and track Service Level Objectives (SLOs), Service Level Indicators (SLIs), and error budgets in partnership with application teams; use them to prioritize reliability work over feature work when warranted.
Lead root cause analysis and blameless post-incident reviews for high-severity production incidents; drive remediation items to closure and identify systemic patterns across applications.
Establish and mature observability practices (metrics, logging, tracing, alerting) so that failures are detected proactively and diagnosed quickly across a heterogeneous, multi-stack estate.
Build capacity planning, load testing, and chaos/failure-injection practices to validate resilience before incidents occur.
Champion a culture of operational excellence, toil reduction, and AI and automation-first thinking across engineering teams.

Cross-Stack Engineering & Inner Sourcing

Make hands-on, code contributions directly into multiple applications spanning different languages, frameworks, and stacks, using an inner-source model to fix reliability defects, add instrumentation, and improve resiliency patterns.
Partner with individual application teams to raise pull requests, follow their contribution standards, and pair with owning engineers so fixes land safely and are properly reviewed and owned long-term.
Identify recurring reliability anti-patterns across codebases (e.g., missing timeouts/retries, unbounded queues, improper connection pooling) and drive standardized, reusable fixes or shared libraries.
Contribute to and help govern internal reliability tooling, shared SDKs, and common patterns (circuit breakers, backoff/retry, health checks) that can be inner-sourced across teams.

Cloud Scalability & Hybrid Architecture

Design and advise on cloud scalability strategies (auto-scaling, load balancing, multi-region/multi-AZ failover, caching, queuing) for workloads that span on-premises data centers and public cloud.
Guide capacity and cost-aware scaling decisions, balancing performance, resiliency, and cloud spend across hybrid deployments.
Evaluate and recommend cloud-native and hybrid resiliency patterns (e.g., disaster recovery, active-active/active-passive architectures, data replication strategies) appropriate for regulated brokerage workloads.

Organizational Awareness & Risk

Bring strong organizational awareness of the operational, financial, regulatory, and reputational risk that production incidents pose to a brokerage business, and factor that into prioritization.
Participate in risk assessments related to system reliability, availability, and disaster recovery, partnering with Risk, Compliance, and Information Security as needed.
Contribute to change management and release governance practices that reduce the likelihood and blast radius of production incidents.
Promptly identify, escalate, and help remediate reliability or security-related incidents in accordance with company policy.

Leadership & Influence

Act as a technical reference and mentor for reliability engineering practices, coaching application teams on operational excellence without formal direct reports.
Influence architecture and design decisions across multiple teams by bringing a reliability and scalability lens to reviews and planning.
Document and evangelize reliability standards, runbooks, and best practices; lead or contribute to internal tech talks and communities of practice.
Partner with engineering leadership to define the reliability roadmap and report on progress against stability goals

So are YOU our next Senior Principal Site Reliability Engineer.? You are if you…

Bachelor's or Master's degree in Computer Science, Information Systems, Engineering, or a related field, or equivalent combination of education and experience.
8+ years of software engineering and/or site reliability engineering experience, including production ownership of business-critical applications; financial services or brokerage experience strongly preferred.
Demonstrated ability to read, debug, and make minor-to-moderate code changes across multiple languages/stacks (e.g., Java, .NET, Node.js/TypeScript, Python) in an inner-source or cross-team contribution model.
Deep experience with cloud scalability strategies on one or more major providers (AWS, Azure, GCP), including auto-scaling, load balancing, multi-region resiliency, and cost-aware capacity planning.
Experience operating and supporting hybrid architectures spanning on-premises data centers and cloud environments.
Strong background in observability tooling (e.g., Prometheus/Grafana, Datadog, Splunk, ELK, AppDynamics, Dynatrace) and building actionable alerting and dashboards.
Practical experience defining and operating against SLOs/SLIs/error budgets and running blameless post-incident reviews.
Experience with CI/CD pipelines and infrastructure-as-code (e.g., Terraform, Ansible, CloudFormation) in support of reliable, repeatable deployments.
Solid understanding of microservices architecture, distributed systems failure modes, and resiliency patterns (circuit breakers, retries/backoff, bulkheads, timeouts).
Familiarity with relational and NoSQL data stores and their operational/scaling characteristics.
Experience with incident management and on-call practices (e.g., PagerDuty, Opsgenie) including leading major incident response
Knowledge of security, audit, and regulatory considerations relevant to brokerage / financial services production systems.
Excellent communication skills, with the ability to influence engineers and stakeholders across many teams without direct authority.
Strong documentation, analytical, and problem-solving skills

Compensation Information:

Base salary range: $150,000 - $190,000
The final compensation package will be commensurate with the successful candidate's experience, skills, and geographic location (Canada). It includes a comprehensive benefits plan and a competitive incentive (bonus) program for Full-Time Permanent roles.
