Principal Software Engineer – Next-Generation API & AI Platform Architecture

Next-Generation API Architecture

Architect and implement customer-facing data and intelligence APIs with clear versioning, SLAs, and backward compatibility.

Define and enforce API contracts for:

Low latency, high throughput endpoints

Agentic workflows (tools, actions, state transitions, handoffs)

Context retrieval and enrichment

Design APIs as durable platform interfaces, not thin wrappers over storage systems.

Establish standards for schema governance, payload design, and service boundaries.

Agentic & ML Platform Integration

Architect service layers that support agentic workflows, including orchestration interfaces, guardrails, and runtime observability.

Build API surfaces that expose model outputs safely and consistently.

Collaborate with MLEs and Data Scientists to move models from experimentation into robust inference services.

Ensure proper lifecycle management, monitoring, and rollback mechanisms for ML-powered endpoints.

Data Platform & Context Hubs

Design and implement service layers that sit on top of the gold-layer system of record.

Build and evolve context hubs derived from authoritative systems of record, enabling consistent entity, identity, or risk context for downstream services.

Ensure APIs are aligned with medallion architecture principles and platform data contracts.

Prevent fragmentation by maintaining strong coupling to canonical schemas and governed data models.

Distributed Systems & Reliability

Design high-throughput, low-latency services supporting batch and streaming workloads.

Implement scalable infrastructure patterns on AWS.

Ensure strong observability, error handling, performance tuning, and cost awareness.

Drive infrastructure-as-code practices and production readiness standards.

Technical Leadership

Serve as a senior architectural voice in design reviews.

Raise the bar on code quality, system design, and operational rigor.

Mentor engineers on API design, distributed systems, and ML integration patterns.

Influence platform direction through technical depth rather than organizational authority

AWS services including Redshift, S3, EC2, and related cloud-native tooling.

Data stores including Elasticsearch, PostgreSQL, Redis, and graph databases (e.g., Neo4j or AWS Neptune).

Experience building high-performance APIs and service layers over heterogeneous data systems.

Familiarity with Databricks/Snowflake and/or SageMaker is a plus.

Experience in cybersecurity, identity, fraud, or risk systems is a plus.
