Responsibilities

This is a hands-on technical leadership role spanning the breadth of Aperia’s product portfolio: the risk platform build, the AI-powered ingestion platform, our residuals and compliance products, client-facing web applications, and a new LangGraph-based agentic application. You’ll report directly to the SVP of Research & Development and act as the connective tissue across these workstreams — leading implementation, driving code-level design decisions, and reviewing designs and code across teams.
This is not a people-management position, and you won’t be working alone at the whiteboard — Aperia has dedicated architects who own the big-picture system design. Your job is to turn that design into shipped, production-quality software and to set the engineering standard for how it gets built. You’ll lead the risk platform build team — a Senior Data Platform Engineer, a Senior DevOps engineer, and a mid-level developer — while spending most of your time in the code yourself: shipping production C#/.NET services, building React frontends, and contributing to our Python-based agentic work. You lead by technical judgment and example, working closely with our architects where workstreams meet.
Lead implementation across multiple concurrent projects — translate architecture from our dedicated architects into technical plans, code-level designs, and shipped software.
Design and ship production C#/.NET services and REST APIs serving high-volume payment data under PCI DSS constraints.
Build and evolve client-facing web applications in React and TypeScript, from component architecture through API integration.
Contribute hands-on to our LangGraph-based agentic application — agent orchestration, tool integration, and the engineering discipline (testing, evals, observability) that makes LLM-powered systems production-worthy.
Own engineering standards across teams: code review culture, automated testing discipline (unit, integration, end-to-end), and CI/CD practices in Azure DevOps.
Deploy and operate services on AKS across Azure and our dual on-premises datacenters, partnering with DevOps on infrastructure and release engineering.
Mentor the engineers on your team — data platform, DevOps, and application developers — through code review, pairing, and design collaboration.
Champion AI-assisted development (Claude Code, Cursor, GitHub Copilot) — help define, document, and enforce team standards for using these tools well.
Participate in design reviews and ADR discussions with the architecture team, bringing an implementer’s perspective.
Guide your team’s data platform work at the integration boundaries between application workstreams and the Microsoft Fabric data estate.
