Lead Product Researcher

Job Title: Lead Product Researcher

Location: Chancery Lane, London (Office-based, hybrid schedule)

Company: Fyxer

Revenue Goal: $100M+ by EOY 2026

At Fyxer, we believe the only sustainable competitive advantage for a startup is the quality and speed of execution.

We are looking for a Research Lead who is more than a researcher. You are a full stack product thinker who uses mixed methods research to drive better bets, faster learning, and stronger commercial outcomes.

We’re not looking for someone to run research and hand over insights. We want someone who helps us think better and decide better. The goal isn’t more decks, it’s higher quality decisions.

You will work directly with our Head of Product, CTO and senior engineers to shape what we build and why.

• Lead discovery for our most important product bets, from early ambiguity to validated direction

• Work directly with engineers and founders from the start of any initiative, not as a handoff but as a core partner

• Design and run the right validation methods for the question at hand: interviews, prototypes, fake doors, usability testing, behavioural analysis, and experiments

• Translate messy qualitative and quantitative signals into clear product direction across short term improvements and longer term strategy

• Embed structured learning loops into how we operate so insight compounds over time

• Raise the bar of research and product thinking across the team by coaching others, introducing scalable frameworks or rituals to get the team closer to customers.

• Systems thinker: You understand customer journeys, funnels, and feedback loops. You connect user behaviour to outcomes and revenue impact, not just isolated features.

• Full-stack research expert: Deeply fluent across qualitative research, behavioural insight, and experimentation. You know how to generate strong signal quickly and choose the right method for the decision at hand.

• Engineering partner: You work closely with engineers and founders, translating user insight into clear problem framing and practical tradeoffs. You influence what we build through evidence and clarity.

• Decision oriented: You know when there is enough signal to move. You help others clarify thinking, sharpen hypotheses, and make confident calls under uncertainty.

• Capability builder: You design research systems that compound over time rather than one off projects. Your work levels up how we do research and discovery across the company, and you introduce frameworks, coach others, and build repeatable learning loops.

You will be the senior research voice within the product organisation, working directly with the Head of Product, CTO, founders, and senior engineers. This is not a support function. You will be embedded in high impact initiatives from day one, helping shape what we build and why.

You will operate at speed. We care about generating signals quickly, making informed decisions, and learning fast. You are comfortable working with imperfect information and tightening thinking as you go.

You will move fluidly between discovery, validation, experimentation, and strategic framing. Some weeks you will be deep in user interviews, other weeks you will be pressure testing a major product bet or refining an existing feature.

You will have significant autonomy. We expect strong judgment, clear communication, and ownership of outcomes.

If there are specific tools you believe are critical to generating better signal or scaling research, we will support that. We want you to design the right setup, not work around constraints.

Why Fyxer?

We are intentional about our team. We believe a small, exceptional team working with extreme focus will always outperform a large, bloated organization.

• Autonomy: We hire people who want ownership and then we actually give it to them.

• Velocity: You will be fast-tracked into senior responsibilities far earlier than at a traditional company.

• Scale: We are on track to hit $100M in revenue by the end of 2026. This is a rare opportunity to join a high-growth rocket ship at the foundational stage.
