About the company
Shellworks is a design-led techbio company building compostable packaging made from a naturally-derived material called Vivomer. Vivomer is positioned as a plastic alternative that stays stable in use, then biodegrades after disposal. Shellworks sells packaging formats across areas like personal care and product containers, with products listed in a catalogue range. Shellworks describes operations in London and frames the work around replacing single-use plastics rather than improving recycling.
Locations and presence
Shellworks is headquartered in London, with roles tied to a London (N4) office. Recent postings describe either fully on-site work or a hybrid pattern that still expects most days in the office.

Shellworks offers some real entry points, including a clearly student-friendly materials internship, but early-career access looks occasional rather than continuous. Shellworks posts salary ranges for at least some roles and shares practical working patterns (on-site vs hybrid), yet the hiring process and early-career support model are not laid out in a consistent, candidate-facing way. Outcomes are hard to score higher because public evidence is thin on progression, conversions, and retention beyond a small number of reviews.
Pillar 1: Early-career access

Score

13.2
/ 20
  • The company advertised a Materials Science & Engineering Internship as a 3-month contract aimed at current students or recent graduates in materials science, engineering, or chemistry.
  • Shellworks has had only a small number of open roles visible at a time, with the current careers page showing a single engineering vacancy rather than a steady stream of junior roles.
  • The company does not publish a recurring graduate scheme, apprenticeship track, or annual internship cohort intake, which limits predictable first-job access.

Pillar 2: Hiring fairness and transparency

Score

11.2
/ 20
  • The company has candidate-reported interview flows that include an initial call followed by a take-home task, with some reports noting fast follow-ups between stages.
  • Shellworks publishes practical role details like expected office days and a salary band plus equity on at least one role, which improves transparency before interview stages begin.
  • The company does not provide a clear, standard “how we hire” outline on the careers site (stages, timelines, feedback norms), so candidates have to infer process details from scattered job ads and reviews.

Pillar 3: Learning and support

Score

12.2
/ 20
  • The company scoped the materials internship around hands-on learning, including operating production-grade polymer processing equipment and running an in-house material characterisation project.
  • Shellworks describes interns working alongside a cross-functional team across manufacturing, materials science, and design, which supports day-to-day learning through close collaboration in a small team.
  • The company does not publish a consistent onboarding, mentorship, or early-career training framework for new hires, so support quality is difficult to verify beyond role-by-role descriptions.

Pillar 4: Pay fairness and stability

Score

13.5
/ 20
  • The company posts pay ranges for at least some roles, including a Product Design Engineer listing with a stated £40k–£50k salary band plus equity.
  • Shellworks lists tangible quality-of-life benefits in postings, including 21 days’ holiday, a birthday day off, and an office closure period in late December, plus catered lunch in the office.
  • The company does not consistently show pay ranges for internships or across all job ads, which makes it harder for early-career candidates to compare offers confidently.

Pillar 5: Early-career outcomes

Score

11.2
/ 20
  • The company has a small number of employee reviews describing a supportive, mission-focused team environment alongside stress during delivery deadlines and evolving processes.
  • Shellworks states that Shellworks shipped the first 100,000 units in 2022 and has been scaling following a seed round, which suggests early hires can work on real products that ship rather than internal-only projects.
  • The company does not publish early-career outcome metrics such as internship-to-offer conversion rates, typical time-to-promotion, or retention by cohort, which caps confidence on long-term outcomes.
