OverviewApplication

At TriEdge Investments, we build technology that helps real businesses operate better. Working across a portfolio of 30+ companies and select partners, we embed with operators to design and ship automation that moves the numbers, including throughput, cost, and reliability. Over time, we turn those hard-won solutions into platform tools that scale across companies, building an intelligent system that brings modern automation to businesses typically overlooked by traditional software.

As a Senior Software Engineer, you will operate as a senior technical leader embedded with operators and clients, owning complex problem spaces from discovery through production. Rather than executing against predefined specs, you will identify the highest-leverage opportunities, shape requirements in partnership with users and executives, and define system architectures that can be scaled and reused across the portfolio. You will remain hands-on in code while setting technical direction, ensuring solutions are durable, secure, and aligned with long-term business outcomes.

What You’ll Do

• Lead deep technical discovery with operators and clients, diagnosing workflows, systemic pain points, and high-leverage automation opportunities across engagements
• Own architecture and delivery of end-to-end systems spanning web, cloud, data, and AI infrastructure, with an eye toward reuse and long-term scalability
• Define and build robust APIs, agentic workflows, and AI/ML-driven systems, setting standards for how intelligent automation is designed and deployed
• Rapidly prototype, develop, validate, and harden solutions in live client environments, balancing speed with production-grade reliability and adoption
• Set technical direction for performance, scalability, security, and resilience, proactively identifying risks and addressing them before they impact customers
• Lead cross-functional technical alignment with product, data, and operators to ensure solutions map directly to business outcomes and portfolio strategy
• Own production excellence in client deployments, driving root-cause analysis, durable fixes, and systemic improvements rather than one-off patches
• Serve as a senior technical authority and trusted advisor to executives and operators while remaining deeply hands-on in code and system design

About You

• 5+ years of full-stack software engineering experience, with demonstrated Staff-level impact in production environments
• Proven experience in leveraging AI development stack to develop enterprise grade applications from end to end, such as Claude code, custom mcp, skills, backend-as-a-service.
• Proven track record of owning ambiguous, high-stakes problem spaces end to end, including direct delivery in client- or operator-facing contexts
• Broad technical depth across the stack (e.g., Python, React/Next.js, SQL/NoSQL, cloud infrastructure), with the judgment to choose appropriate tools and architectures
• Strong API and systems design expertise, including defining interfaces and patterns that scale beyond a single team or deployment
• Hands-on experience integrating AI/ML into production systems, with an understanding of tradeoffs across performance, cost, reliability, and compliance
• Exceptional communicator, capable of influencing engineers, operators, and executives through clear technical reasoning and written design artifacts
• Pragmatic technical leader with a strong bias toward ownership, accountability, and forward-deployed execution
• Effective operating in complex environments, including legacy systems, heterogeneous stacks, and regulated or compliance-driven domains
• Fluent in AI-assisted development, using modern tooling to increase leverage while maintaining high standards for code quality and system integrity
• Bachelor’s degree minimum

Why Join TriEdge Investments

• Play a key role in reshaping private equity with AI-powered platforms that scale
• Help digitize and transform real businesses, not just build another SaaS product
• Be at the forefront of AI and automation across financial services and healthcare
• Work closely with operators and executives to deliver solutions that matter
• Join a culture that values clarity, speed, reuse, humility, and ownership
