Senior Software Developer

Job Opportunity only available for professionals located in Latin America.

We're seeking a Senior Software Developer to join our HR Technology & Shared Services development team
, a specialized engineering group responsible for building secure, scalable, and business-critical platforms that support enterprise functions across the firm.

This is a full-stack engineering role within a high-performance quantitative trading firm, where precision, security, and craftsmanship matter
. The team designs and builds internal platforms that integrate with best-in-class third-party systems (UKG, ADP, payroll, compliance, and others) while also developing custom solutions that cannot be purchased off the shelf.

The group operates a dedicated on-premises hardware environment to support systems responsible for highly sensitive firm data. As a Senior Developer, you will work end-to-end — from architecture and application design to deployment and operational support — in collaboration with experienced engineers and cross-functional stakeholders.

• Advanced English level (B2/C1/C2) to ensure fluent communication across teams is a Must.
• 10+ years of hands-on software development experience.
• Strong proficiency in C# or Java.
• Experience with SQL, Web Development, and API-driven architectures.
• Experience working with AI-assisted tooling (Copilot, Cursor, Claude Code, etc.).
• Interest in understanding systems beyond code — including deployment, data flow, and reliability.
• Strong collaboration and communication skills across technical and non-technical teams.
• Any experience deploying solutions using AI for inference is a plus.
• Bachelor's degree in Computer Science, Engineering, Mathematics or a related discipline. Relevant experience can be substituted for education.

• Build solutions leveraging LLMs running on our on-prem GPU infrastructure
• Design and build secure, scalable applications supporting critical business functions
• Architect and maintain integrations across enterprise systems (HR, payroll, compliance, compensation)
• Build internal tools and platforms where commercial solutions do not meet business needs
• Work across the full SDLC: architecture development deployment monitoring
• Contribute to a dedicated on-premises infrastructure environment
• Collaborate with engineers, analysts, and system owners to translate complex requirements into production-ready systems
• End-to-End Ownership Engineers contribute across application, integration, and infrastructure layers.
• Security-Focused Engineering Systems support highly sensitive data (e.g., compensation, performance, firm-wide workflows) and are designed with strict isolation and reliability standards.
• Complex Systems Environment Multiple integrations, diverse data flows, and enterprise-scale workflows require thoughtful system design and strong engineering fundamentals.

• Competitive salary in USD.
• 100% Remote work.
• Type of contract:
  Independent Contractor with Venon Solutions LLC.
• Contract duration:
  Long-term.
• Benefits: 2 weeks of PTO (paid time off).
