Overview

Fictiv is reimagining how manufacturing works in an AI-first world.

Our AI Innovation Team operates like an internal startup—focused on discovering, validating, and scaling entirely new product capabilities across both Fictiv and Misumi. This isn’t about incremental improvements or maintaining existing systems. It’s about identifying what should exist next and building it from the ground up.

As a Senior Software Engineer on this team, you’ll work on early-stage ideas, rapidly turning concepts into functional prototypes, testing them with real users, and evolving the strongest signals into production systems.

If you’re energized by ambiguity, driven by impact, and motivated by building things that don’t yet exist, this role is designed for you.

• You think like a builder and an owner, not just an implementer
• You’re motivated by solving real business problems—not just writing code
• You move quickly, test ideas early, and learn from real-world feedback
• You’re comfortable operating with limited structure and evolving direction
• You challenge assumptions—including your own—and iterate based on evidence
• You communicate clearly and bring others along in your thinking

• Location: Oakland, CA (onsite collaboration expected)
• Travel: Minimal (0–10%)

• Salary range: $160,000 – $200,000, depending on experience
• Comprehensive medical and dental coverage
• 401(k) plan
• Generous PTO and leave programs

We’re actively seeking teammates who

• Bring diverse perspectives and experience to our culture and company.
• Excel at being part of a strong, empathetic team.
• Thrive in an environment emphasizing respect, honesty, collaboration, and growth.
• Have an ‘always learning’ mindset that celebrates learning, not just wins.
• Help us continue to build a world-class organization that values the contributions of all of our teammates

We encourage applications from members of underrepresented groups, including but not limited to women, members of the LGBTQ community, people of color, people with disabilities, and veterans.
