The SRE will own key responsibilities across billing, security, business intelligence/data science infrastructure, technical debt remediation, and AWS-based data engineering. This role requires a self-starter who is highly curious, excited about financial markets, and eager to take full ownership (Directly-Responsible Individual – DRI) of processes, pipelines, and improvements. It is a hands-on engineering position suited for someone who thrives in a small, high-impact team with shifting priorities and minimal oversight.

Duties & Responsibilities

  • Collaborate with engineering and BI/DS functions on infrastructure needs, data source integration, and pipeline enhancements.
  • Support proof-of-concept efforts, prototype new tooling, and assist with vendor evaluations.
  • Help manage AWS infrastructure, permissions, and resource provisioning needed for BI and analytical workloads.
  • Proactively raise observations or concerns related to data quality, pipeline stability, or analytical tooling.

• Technical Debt and Operational Excellence

  • Assist the team in addressing ongoing technical debt, including cleanup, patching, refactoring, and modernization.
  • Take ownership of repetitive tasks, deployments, documentation, and operational workflows to reduce team overhead.
  • Ensure all changes follow proper audit trails, checklists, and change-management processes.
  • Maintain high-quality documentation, runbooks, diagrams, engineering design specs, and operational logs.
  • Proactively highlight high-priority issues, gaps, or improvement opportunities.

• General Engineering Responsibilities
  • Participate in on-call rotations, respond to incidents, perform first-level triage, and escalate when necessary.
  • Communicate clearly, promptly, and respectfully - especially in public Slack channels.
  • Coordinate with vendors (platform operators, network providers, tools vendors) to ensure timely resolution and SLA compliance.

Mindset & Team Expectations

• Learn new tools and technologies quickly, adapt to shifting priorities with flexibility and resilience.
• Collaborate openly, ask questions early, and always seek clarity when needed.
• Operate transparently: work in public channels, document decisions, ensure shared understanding.
• Take ownership - be the DRI for systems, workflows, and improvements you manage.
• Be very curious, passionate about markets and technology, and willing to learn about trading platforms and stock-market operations.
• Voice opinions thoughtfully, understand context, “read the room,” and know when to pivot or persevere.

Required Skills & Abilities 

• Strong AWS experience, especially with data pipeline architectures.
• Proficiency with Terraform/Terragrunt and GitHub workflows.
• Expert scripting skills.
• Experience with Go (preferred) and Python (legacy).
• Familiarity with vulnerability management tools (Tenable or similar).
• Strong Linux fundamentals.
• Ability to manage compliance-oriented, audit-driven workflows.
• Strong communication and documentation habits.
• Ability to triage issues independently and escalate appropriately.

Education & Experience

• Experience in regulated or compliance-heavy environments (finance, fintech, health, etc.).
• Experience in data-driven systems, billing or financial reporting pipelines, or BI/DS infrastructure support.
• Prior vendor coordination or SLA-driven operational experience is a plus.
• Demonstrated history of direct responsibility for, background or strong interest in financial markets is highly desirable.
