Vicente Reig Rincón de Arellano
Fractional Engineering Lead | AI & Engineering Strategy
I’m a Product-minded Engineer and Technical Product Manager with an entrepreneurial bent. I help teams aligning engineering efforts with real customer needs.
I've built and scaled products at startups, hyper-growth companies, and large enterprises, including New Relic, Apple, and Atlassian. My approach is pragmatic: I get things done and focus on what moves the needle.
Currently, I help startups navigate the challenges of building and selling AI-driven products—steering engineering focus, improving product-market fit, and ensuring sales traction in a fast-moving AI market.
I'm a Product-minded Engineer with an entrepreneurial bent. I'm hands-on, curious, and pragmatic. I've built things at scale, at big corporations, companies in hyper growth stage, and startups. I have strong technical foundations. I get things done.
I'm interested in hearing from you; get in touch!
Services
Build What Customers Actually Want
Too many teams chase ideas without validating demand. I help companies prioritize work that solves real customer problems instead of theorizing.
- Refined product positioning based on customer insights.
- Execution alignment between engineering, sales, and GTM teams.
AI & GenAI Execution Without the Hype
Execution matters. I help teams focusing on what customers will pay for.
- Unlock engineering potential—I’ve led teams to build LLM-powered features, AI agents, and automated workflows.
- Deliver AI features customers actually use, not just AI experiments.
Engineering That Moves the Business Forward
Technical complexity can become a distraction. I help engineering teams stay focused, ship faster, and build scalable architectures that align with business needs.
- Process & execution optimization—speed up releases, reduce inefficiencies.
- Scaling & performance tuning—I’ve optimized Rails apps to run 10x faster.
- Seamless third-party integrations—APIs, data pipelines, and automation.

Rates
A typical contract is for 1 month of work. I am normally booked 1 to 3 months in advance.
I am open to shorter contracts, but prefer longer ones. For shorter contracts, we will divide my monthly rate by the number of days you want, and add a small amount of overhead.
Work Highlights
🏗 Reshaping AI Product Strategy at Bounti
As Technical Product Manager, I ensure engineering stays focused on building real, sellable products instead of chasing theoretical AI projects.
- Navigated startup chaos—helped streamline priorities while leadership chased multiple ideas.
- Steered product toward revenue goals—refocused on sales blockers and GTM alignment.
- Democratized AI development—broke down GenAI gatekeeping so the whole team can build AI-powered products.
Prior Work Highlights
I worked across startups, hyper-growth companies, and enterprise tech, delivering high-impact engineering and product solutions that helped businesses scale, optimize performance, and drive revenue.
🚀 MVPs & Scalable Products
