80d • $150,000 - $260,000

About The Position

Our client is the leading AI tool for wealth managers and financial advisors, automating critical tasks like notetaking, compliance, and CRM updates. They have secured $25 million in total funding and are trusted by enterprise firms. They are seeking a high-caliber Software Engineering Leader (Staff, Senior, Principal) to join their small, high-velocity team. This role requires full ownership of feature development—from design through deployment—within their highly scalable, distributed Elixir ecosystem. You will be instrumental in building and enhancing their core AI-powered capabilities.

Requirements

• 5+ years of experience as a software engineering leader (staff, senior, principal, etc.).
• Strong experience with the core concepts of the modern tech stack, particularly distributed systems and full-stack ownership.
• Deep passion for taking a feature from design to production and ensuring its long-term reliability.

Responsibilities

• Own End-to-End Features: Design, build, and deploy features quickly within an Elixir/Phoenix/LiveView monolith, taking full responsibility for code reliability in production.
• Scale Distributed Systems: Work in a distributed Elixir environment (using libcluster on Kubernetes) to ensure high scalability, reliability, and performance.
• Build Integrations: Maintain and build new third-party integrations (already 30+) using consistent adapter patterns and the Tesla/Finch stack.
• LLM Feature Development: Engage with cutting-edge LLM-powered features (using OpenAI and Anthropic), including prompt routing, caching, JSON mode, function calling, and managing embeddings using pgvector.
• Infrastructure as Code: Collaborate on infrastructure in a fully Terraform-managed GCP/GKE environment.
• Ensure Quality: Contribute to testing using LiveView tests, Hammox for contracts, and Wallaby for E2E flows. Use observability tools (AppSignal, Prometheus, Grafana) for debugging.
• Work at High Velocity: Ship small features and bug fixes daily, with larger features delivered in days, not weeks.

Benefits

• Salary: $150K - $260K (Based on YOE; potential flexibility for more tenured candidates)
• Equity: 0.066% – 0.1%
• Commitment to Equality and Accessibility: At MLabs, we are committed to offer equal opportunities to all candidates.
