About the Role
Our client is building a native macOS application that delivers AI-powered data insights for business users. This is a systems-level contract engagement where you'll work across AI runtime, platform integrations, deterministic data execution, or adaptive macOS UI based on your strengths and interests.
The application follows a structured, multi-stage pipeline that transforms natural language into verified and traceable results. Engineers will work within a layered architecture consisting of 20+ Swift Package Manager (SPM) targets with strict dependency boundaries. This role is ideal for candidates who have experience shipping production macOS desktop applications and enjoy owning end-to-end technical responsibilities.

Key Responsibilities

Own one or more technical areas within a native AI pipeline, including:
- AI runtime and orchestration
- Platform integrations
- Deterministic execution
- Adaptive macOS UI
Design and implement production-quality Swift code within a layered SPM architecture (20+ targets) while maintaining strict dependency boundaries.
Build AI orchestration capabilities, including:
- Structured output extraction
- Multi-stage routing
- Tool calling
- Context management
- Response synthesis
Develop platform integrations such as:
- Protocol-based connector clients
- Enterprise data access
- Entitlements
- Sandboxing
- Identity management
- Persistence boundaries
Build deterministic execution pathways including joins, aggregations, rankings, filters, and complete data provenance.
Develop adaptive macOS user interfaces using SwiftUI with AppKit interoperability, supporting:
- Desktop window management
- Keyboard-first workflows
- Streaming content updates
- State management
- Accessibility
Write and maintain automated tests using XCTest and Swift Testing.
Ensure shared mutable state is implemented using actors or Sendable value types with proper Swift 6 concurrency isolation.

Required Qualifications

5+ years of professional software engineering experience using Swift.
Experience shipping native macOS desktop applications (not iOS-only).
Strong understanding of Swift concurrency, including:
- Actors
- Async/Await
- Sendable
- Structured concurrency
- Typed throws
Experience working with layered, modular Swift Package Manager (SPM) architectures.
Strong knowledge of protocol-oriented programming and dependency injection.
Experience working with pre-commit hooks, SwiftLint, SwiftFormat, and enforced commit conventions.

AI Runtime & Orchestration

LLM integration, including guided generation, structured output, tool calling, and streaming inference.
Experience with ML inference frameworks and model orchestration.
Token budget management.
Prompt composition.
Multi-stage pipeline orchestration.
Evaluation and benchmarking of non-deterministic AI outputs.

Platform & Integrations

Protocol-based connector/client architectures (SSE, stdio, REST, OData).
macOS system services including:
- Process lifecycle management (launchd, SMJobBless)
- Entitlements
- Sandboxing
Code signing, notarization, and installer packaging for macOS distribution.
Enterprise data access patterns and pagination strategies.

Deterministic Execution & Data Systems

TabularData or equivalent data frame processing in Swift.
Experience implementing joins, aggregations, rankings, filters, and provenance tracking.
Graph or vector retrieval systems.
Entity resolution.
Schema-driven field matching and query planning.

macOS Adaptive UI

Production SwiftUI applications with AppKit interoperability.
Adaptive layouts and multi-panel desktop windowing.
Keyboard-first navigation.
