Thank you so much for sharing your experience! It’s incredibly encouraging to hear how CPI fosters such a collaborative and inclusive environment. Your comments about the open management culture, flexible working, and the company’s mission-driven approach really highlight what makes CPI special. It’s great to see long-term employees like yourself feeling supported and empowered, especially with opportunities to engage beyond the organisation. We appreciate your honesty about the IT changes too, and we’re optimistic that improvements will continue. Thanks again for being part of what makes CPI a great place to work!

Pros

Good work life balance Friendly people

Cons

Weak progression and compensation leads to a mid-level void The experienced staff that stick it out have little incentive to move the needle Business is grant based, money gets sucked up by inefficiencies. End up delivering essays instead of real products Support staff like IT, HR and Procurement thrive on writing rules, systems and obsessing over health and safety. Zero effort to reduce blockers for engineers. IT actively try to increase them. HR run time-wasting training courses, which are belittling to scientists and engineers

Thank you for taking the time to share your feedback. We’re pleased to hear your positive comments about the work–life balance and the friendly, supportive colleagues across the organisation. We also recognise the concerns you’ve raised around career progression, compensation, and the experience of working within a grant‑funded environment. These are important topics, and we understand how they can shape day‑to‑day experience and long‑term engagement. On progression and compensation specifically, we want to clarify that we have made significant changes this year to strengthen fairness and transparency. Our approach to pay is guided by three principles: pay fairly as one company, pay sustainably, and performance‑led pay. We have revised our merit process to ensure increases are awarded fairly across roles and salary ranges. Updated guidance on our pay framework and the 2026 merit process has been shared with colleagues to ensure clarity and alignment. We appreciate your suggestions on giving teams greater autonomy and investing more deeply in specific areas. Exploring new ways of empowering teams and improving commercial outcomes is an ongoing conversation, and feedback like this helps shape that thinking. Thanks again for your feedback and we wish you the best for the future.
