The Entry Point

42.’s founder needed a researcher to test early ideas across trading, biology and other scientific fields. With no fixed roadmap, the role called for someone who could define experiments independently and adapt as new evidence emerged.
Challenge
A candidate's qualifications on paper couldn't reveal whether they would thrive in an ambiguous research environment. The role required choosing research directions independently and adapting as new evidence emerged.

Candidates also needed clarity: how would their performance be assessed without predefined milestones, and how committed was the company to funding this new R&D direction?
Academic ML background
Strong scientific foundations; trading or biotech experience was optional.
Adaptable mindset
Comfort with open-ended experiments and changing research directions.
Open seniority
Strong graduates and experienced researchers were both considered.
Founder collaboration
Direct reporting, independent decisions and minimal formal structure.

Based in the Netherlands, with relocation support.

What's next

The team added a dedicated researcher reporting directly to the founder, enabling early-stage hypothesis testing before committing full engineering resources.

This allows the core quantitative team to maintain focus on live trading infrastructure while the founder evaluates ideas across trading, biotech, and natural sciences.
While long-term research outputs are pending, this hire marks the operational step toward 42.’s target: leveraging capital from quantitative trading to fund fundamental scientific research.
Client's testimonial

Client's testimonial
“We’ve worked with Lucky Hunter for three months, and in that time they closed six roles, including low-level C++/MLIR engineers and ML researchers. The team refined profiles, ran market analysis, suggested donor companies, and quickly adjusted the search. All roles were filled effectively, even with challenges involved.

We truly appreciated their coordinated teamwork and responsiveness. Highly recommended!”

Recruiter's feedback
“Having partnered with 42. on previous searches, we understood their internal structure and culture. That allowed us to pitch a role without fixed deliverables or a clear roadmap with complete clarity.

By laying out the actual work environment during the initial screen, we ensured only candidates aligned with that structure made it to the founder.”
