About the Role

We are hiring a highly technical and hands-on Head of Engineering to own the entire engineering function of a fast-growing SaaS platform. This role combines deep backend engineering, distributed systems architecture, AI infrastructure, and technical leadership in a fast-moving startup environment.

This is not a purely managerial role. You will actively write production code, make architectural decisions, oversee infrastructure reliability, and guide a lean engineering team while helping scale a platform operating across multiple services and AI-powered workflows.

The ideal candidate thrives in startup environments, takes ownership of systems end-to-end, and understands how to balance rapid product development with long-term scalability and reliability.

What You’ll Own

Backend Architecture & Engineering

Design, build, and maintain scalable backend systems using .NET 8.0, C#, ASP.NET Core, and Entity Framework Core
• Own system architecture across 14+ independently deployed microservices
• Implement Clean Architecture and Domain-Driven Design (DDD) principles
• Deliver new product features, optimize existing systems, and resolve performance bottlenecks
• Improve system scalability, maintainability, and engineering standards across the codebase

AI Systems & LLM Infrastructure

Design and manage production-grade AI and LLM pipelines across multiple providers
• Build scalable workflows for personalization, segmentation, automation, and AI-assisted features
• Optimize prompts, orchestration logic, failover systems, and provider routing strategies
• Monitor token usage, rate limits, latency, and cost efficiency across AI systems
• Integrate AI-assisted development workflows and tooling into engineering operations

Databases & Data Infrastructure

Manage and optimize MySQL, Redis, and MongoDB production environments
• Oversee caching strategies, analytics pipelines, event-driven systems, and bulk data operations
• Ensure strong performance, reliability, and data consistency across distributed services
• Improve database architecture, indexing, and query performance

Infrastructure, DevOps & Reliability

Own Linux-based infrastructure, CI/CD pipelines, deployments, and operational reliability
• Implement centralized monitoring, observability, alerting, and logging systems
• Proactively identify scalability, reliability, and performance risks before they impact users
• Maintain high platform uptime and deployment stability across environments

API Integrations & System Resilience

Manage and maintain 25+ third-party API integrations in production
• Design retry logic, graceful degradation systems, fallback strategies, and provider failover handling
• Ensure platform stability during outages, API failures, or degraded external services
• Improve resilience and fault tolerance across all external dependencies

Team Leadership & Engineering Standards

Lead and mentor a small engineering team through code reviews, architecture guidance, and technical feedback
• Establish and enforce engineering best practices, workflows, documentation standards, and deployment processes
• Collaborate directly with leadership and founders on product direction and technical roadmap planning
• Create a culture of ownership, execution quality, and engineering excellence

What Makes You a Great Fit

Senior-level engineer comfortable owning systems end-to-end
• Strong architectural thinker who still enjoys hands-on coding daily
• Calm under pressure and highly capable in fast-moving startup environments
• Deeply analytical with strong problem-solving instincts
• Strong communicator capable of aligning engineering decisions with business goals
• Passionate about scalability, reliability, AI systems, and engineering excellence

Required Experience & Skills

Deep expertise in .NET 8.0, C#, ASP.NET Core, and Entity Framework Core
• Strong experience designing distributed systems and microservice architectures
• Production experience with MySQL, Redis, MongoDB, and event-driven systems
• Hands-on DevOps experience with Linux infrastructure and CI/CD pipelines
• Experience managing large-scale API integrations and distributed workflows
• Proven experience building and operating AI/LLM systems in production env
