Job summary

Vantora, formerly UP.Labs, is building multi-venture software ventures in collaboration with leading industrial manufacturers. As a Staff Engineer (Founding Team), you will own end-to-end product delivery across stacks and guide architectural decisions in high-ambiguity environments.

This hands-on role shapes technical foundations, product direction, and venture traction. You will work across multiple ventures, collaborating with venture leads and PMs, and applying AI as a multiplier to speed

Qualifications

• 6+ years of software engineering experience, including time in early-stage 0→1 environments.
• Proven ability to build and ship full-stack applications end-to-end.
• Demonstrated use of AI to accelerate development or product capabilities.
• Comfort operating in ambiguous environments where both the problem and solution are evolving.

• Strong communication skills and the ability to influence decisions.

Responsibilities

• Take concepts from zero to a working product and real-world validation.

• Shape product direction alongside venture leads and PMs, not just execute against specs.
• Design and build rapid validation loops to test assumptions and de-risk ideas early.
• Architect and implement core systems, models, and integrations from scratch.
• Use AI as a force multiplier across development and product capabilities.
• Make deliberate tradeoffs between speed and durability based on venture stage.
• Operate effectively with incomplete, evolving, or imperfect inputs to get to working solutions quickly.
• Work directly with stakeholders to validate workflows and refine solutions.
• Identify and mitigate technical and product risks early.
• Contribute across multiple ventures, applying patterns and learnings to accelerate future builds.
