About this role
LOWRATECO - FOUNDING LEAD ENGINEER
We are seeking a highly motivated and hands-on Founding Lead Engineer to build and own the core technology platform of a venture-backed, early-stage company disrupting the multi-trillion-dollar mortgage industry. This is a rare opportunity to move an entire industry by architecting an end-to-end AI automation solution.
You will be the first in-house engineering hire, responsible for migrating our product from an external agency to an internal, scalable platform, and then rapidly building out the next generation of our AI-driven features.
ROLE RESPONSIBILITIES:
- Hands-on Engineering and Architecture: Act as the primary engineer, leading the design, development, testing, and deployment of our mission-critical, cloud-native platform.
- AI Agent Development & Integration: Integrate, scale, and manage proprietary and third-party AI agents (LLMs like Gemini/GPT) to automate core business functions, including sales, processing, and underwriting.
- System Ownership & Migration: Take ownership of the existing infrastructure (GCP, Python/FireStore, Salesforce integration) and strategically plan and execute the migration from the current external vendor to a robust, in-house system.
- Technical Roadmapping & Decisioning: Drive all major technical decisions, setting the standards for code quality, architectural integrity, and security from the ground up.
- Team Building: Play a critical role in defining the future engineering team structure and participate in the recruitment, mentoring, and scaling of the future engineering staff.
- Product Collaboration: Work closely with the CEO and product stakeholders to translate an ambitious product vision—specifically the transition to full AI processing and underwriting—into technical specifications and delivered features.
WHAT YOU BRING
- Experience: 4+ years of professional experience in full-stack software development, with a strong emphasis on backend and cloud architecture.
- Startup DNA: Proven experience working in a high-growth, early-stage startup environment or as a Founding Engineer, demonstrating the ability to thrive with high autonomy and limited resources.
- Technical Foundation: Deep experience with modern cloud environments, preferably GCP, and expertise in backend languages like Python (relevant for AI/ML work) or similar distributed systems languages.
- System Design: Strong background in designing and deploying cloud-native, distributed systems capable of handling high transaction volumes and integrating multiple external APIs.
- Product Mindset: Ability to quickly understand complex business needs and apply a product-first approach to engineering solutions, focusing on speed and value delivery.
- Founding Engineer Traits:
- Exceptional self-starter and problem-solver.
- Comfortable with ambiguity and rapid iteration.
- A strong bias for action and delivery.
WHAT WE OFFER
- Significant Equity: Generous founder-level equity compensation for taking on a foundational role.
- Massive Impact: The chance to change a 100-year-old industry and work on complex, high-impact AI challenges.
- High Visibility: Direct collaboration with the CEO, VCs, and key partners like Rocket Mortgage.
- Competitive Salary: A competitive base salary, targeting the $150k - $180k range, commensurate with experience and potential.
