Hello everyone!

 

We are looking for an E-liquid Mixologist for our client in the Czech Republic — a manufacturer operating in a highly regulated e-liquid and vaping category.

 

About the role:

This is not a research-only flavour job, not paper-only regulatory work, and not a molecule-from-scratch flavourist position. You sit inside our Product Discovery Engine, a structured pipeline from market signals to product launch, and own the Lab & Formulation stage.

 

You are the hands-on owner of company's lab loop that bridges Operations (compliance-ready, stable, repeatable production quality) and Product Discovery (benchmarking competitors and building high-fidelity copies from provided briefs). You use benchmarks, sensory evaluation, and regulatory constraints to decide what we test, what we kill, and what we approve.

 

What professional skills are important for us?

  • Proven hands-on experience with e-liquid flavour development / mixology (real compounding, iteration loops, sensory evaluation);

  • Practical sensory analysis of vaping products, including nicotine-containing e-liquids;

  • Deep component-level understanding (sweeteners, coolants, acids, extracts, carriers) and their impact on stability, hardware performance, and taste;

  • Working literacy in TPD / EUCEG and basic CLP (enough to generate compliance-ready data inputs);

  • Comfortable in a production lab / cleanroom environment: precision, hygiene, repeatability, routine-heavy work;

  • Strong documentation discipline: versioning, traceability, reproducibility;

  • Experience collaborating with external analytical laboratories;

  • Understanding of laboratory standards and testing practices applicable to the e-liquid industry;

  • Ability to set up a workplace for execution of the role's tasks (lab setup, equipment, workflows);

  • High proficiency in spreadsheets (Google Sheets) for cataloging and lightweight analysis;

  • Professional English for supplier and flavour-house communication;

  • On-site availability in Brandýs nad Labem.

 

Key responsibilities:

1. Competitive Benchmarking & Copy Development (≈ 50%)

- Build and maintain a benchmark library of top competitor e-liquids (samples, sensory notes, key parameters);

- Translate benchmark profiles into versioned copy candidates using structured compounding and iteration loops;

- Convert subjective feedback (e.g. “too sweet”, “flat”, “harsh”) into comparative internal scales and data points;

- Close loops with clear decisions: Kill / Iterate / Approve, supported by concise decision notes.

 

2. Compliance & Production Quality Enablement (≈ 50%)

- Partner with QA/Regulatory to keep formulations compliance-ready (TPD/EUCEG inputs, traceable compositions, basic CLP checks);

- Convert the R&D gold standard into measurable QC targets and tolerances for mass production;

- Support investigations of quality deviations or complaints with lab checks and corrective-action hypotheses;

- Evaluate liquid ↔ hardware trade-offs, including coil performance and gunk buildup behavior.

 

3. Supplier & Flavour-House Collaboration

- Own the flavour sample pipeline: briefs, requests, receiving, logging, evaluation, structured feedback;

- Provide clear, constraint-aware feedback to accelerate supplier iteration (compliance, stability, cost, hardware compatibility);

- Maintain an approved components and substitution rules knowledge base to reduce rework and surprises.

 

4. Lab System, Library & Testing Protocols

- Maintain a structured digital + physical catalog of all samples and iterations (IDs, versions, dates);

- Own the physical “Gold Standard” reference library and ensure every iteration is compared against it;

 

How you will work:​

  • Hands-on and output-first: samples, iterations, decisions — not theory for theory’s sake;

  • Evidence-first: benchmark → measure → document → decide;

  • Fast loops with control: fail fast without chaos;

  • High ownership, low overhead, low politics;

  • Respect Operations time by shipping clean, decision-ready artifacts;

  • AI-assisted workflows are welcome where they increase throughput, with explicit validation steps.

​

What success looks like:

​

In the first 30–60 days:

  • A working benchmark library (samples + structured sensory notes + traceable IDs);

  • A repeatable lab loop: versioning, testing cadence, decision notes (Kill / Iterate / Approve);

  • First wave of competitor copy candidates with clear gaps and next-step logic;

  • A usable coil performance / gunk buildup test approach;

  • Cleaner, more structured compliance-ready inputs.

 

In 3–6 months:

  • QC has clear gold-standard targets and tolerances for priority SKUs;

  • Less ambiguity between R&D, QA, and Production on what “good” means;

  • Faster benchmarking and copy development cycles with less rework;

  • Production launches with fewer surprises under regulatory scrutiny.

 

We offer:

  • Full-time role with long-term cooperation;

  • High autonomy and real ownership of the lab function;

  • Direct collaboration with Operations, Product, and suppliers;

  • A pragmatic, senior team in a regulated, technically interesting category.

 

Conditions:

  • Location: Brandýs nad Labem, Czech Republic

  • Format: On-site production lab + occasional remote supplier calls

  • Contract: Full-time

  • Trial period: yes (3 months)

  • Overtime: no, outcomes matter more than hours

 

Hiring process:

  • Recruiter screening call — ~20–25 min;

  • Short prep task — ~30–60 min;

  • Single in-depth interview — ~90 min (with cross-functional segment);

  • Optional short CEO culture-fit call for senior candidates.
