SENIOR SOFTWARE & ML ENGINEER (AUTONOMOUS VEHICLES / ROBOTICS)

REMOTE (OPTIONAL AUSTIN, TX OFFICE)

$150,000 – $175,000 BASE + BONUS + EQUITY + BENEFITS

The Opportunity

We’re partnering with a fast-growing robotics and autonomous systems startup focused on vehicle navigation in GPS-denied environments. This is not a research role – you’ll be building production-grade software and ML systems that run inside vehicles for military, defense, and commercial clients.

The team is flexible on seniority and open to mid-level through senior engineers who enjoy hands-on building, experimentation, and deep technical ownership.

What You’ll Be Working On

• Building and maintaining software for vehicle localization and navigation without GPS
• Developing sensor fusion, mapping, and ML-driven algorithms to integrate with vehicle hardware and firmware
• Reverse-engineering vehicle data streams and working with limited documentation
• Prototyping and iterating rapidly to solve real-world challenges in off-road or complex environments
• Collaborating closely across software, ML, and vehicle integration teams to design robust systems
• Owning large chunks of the stack, from embedded C++ systems to ML algorithms and data processing pipelines

What We’re Looking For

• Strong experience in C++ (systems-level, embedded, or robotics applications)
• Hands-on experience integrating software with hardware or vehicles
• Solid computer science fundamentals, including data structures, algorithms, and software architecture
• Comfortable working with limited tooling and documentation, and solving ambiguous problems
• Curious, resourceful, and entrepreneurial mindset with a desire to grow as an engineer

Nice to Have

• Autonomous driving or wheeled robotics experience
• ML experience for non-CV / non-LiDAR systems
• GIS, mapping, or topographical data experience
• Particle filters or localization algorithm knowledge
• PCB / firmware development experience
• Open-source contributions

Why This Role

• Real ownership over production-grade systems – what you build runs in vehicles
• Opportunity to work on cutting-edge autonomous vehicle and robotics technologies
• Flexibility on seniority and career trajectory, with future leadership opportunities
• Competitive compensation, equity, and room for impact in a growing startup
• Hands-on, scrappy, and collaborative team culture – low ego, high technical depth

If you’re excited to build real, deployed vehicle systems and ML solutions, not just prototypes, and want meaningful ownership on a fast-moving robotics platform, APPLY.

MACHINE LEARNING ENGINEER (FOUNDATIONAL AI / RISK SYSTEMS)

REMOTE – UNITED STATES

$150,000 – $190,000 BASE + MEANINGFUL EQUITY + BENEFITS

The Opportunity

We’re partnering with a fast-growing fintech startup building a new category at the intersection of commercial rent, cash-flow intelligence, and applied AI.

This is a foundational machine learning role, not a research position. You’ll own the systems that make real financial decisions in production, working directly with the founding team.

What You’ll Be Working On

• Build and own underwriting and risk decisioning models used in production
• Analyze transaction-level financial data to identify key risk and performance signals
• Design ML systems that adapt to changing cash flow and user behavior
• Implement feedback loops that learn from real repayment outcomes
• Partner closely with founders on product and risk decisions

What We’re Looking For

• 4+ years building and shipping ML systems in production
• Strong data analysis skills with messy, real-world financial data
• Experience deploying Python-based ML models
• Ability to work independently with high ownership
• Decision-oriented mindset (focus on outcomes, not just models)
• Experience in risk, underwriting, or credit modeling
• Fintech or transaction-level data exposure
• Practical use of LLMs for classification or signal extraction

Tech Stack (Required / Core)

• Python for ML model development and data analysis
• Production ML deployment (risk scoring, thresholds, model iteration)
• SQL / PostgreSQL for working with transactional data
• Cloud environment (GCP or similar)
• Backend integration with Node.js / TypeScript-based systems

Why This Role

• As the first ML hire, you’ll own greenfield systems that control real financial outcomes, collaborate directly with founders, and grow into a long-term leadership role with meaningful equity.

If you’re motivated by building ML systems that directly affect real businesses, real cash flow, and real outcomes, APPLY.
