About The Role
We’re looking for a Product Manager to own the product lifecycle for our Interface team, the team responsible for building the user-facing features of Scenario Builder, our flagship energy system modelling tool.
Scenario Builder enables policymakers, planners, and investors to rapidly build, analyse, and share energy system models without coding expertise. This role puts you at the heart of how that product takes shape: translating high-level product direction into detailed, executable specifications, running agile ceremonies, conducting user research, and ensuring every feature that ships meets a clear definition of done.
You’ll work closely with the Head of Product, a Principal Engineer, and a Product Designer to ensure the team builds the right thing, builds it well, and communicates it effectively. This is a hands-on, embedded role.
Responsibilities
Product specification and delivery
- Write product requirements documents (PRDs) with clear acceptance criteria that engineering can confidently build and test against
- Own the definition of done for every feature, ensuring nothing ships until it genuinely meets the bar
- Conduct exploratory and user research to validate product direction and inform prioritisation
- Manage the product backlog, ensuring work is well-scoped and sequenced for sprint planning
- Run the Interface team’s agile ceremonies: daily standup, sprint planning, sprint review and retro, and a weekly refinement session
Communication and coordination
- Own product marketing for Scenario Builder: identify the key headline for each release, draft compelling newsletter content and social posts, and coordinate with the marketing team to bring features to life
- Produce and maintain user-facing product documentation, including the Scenario Builder pages on the marketing site and docs site
- Run a fortnightly product and marketing sync to keep communications aligned with the delivery roadmap
- Act as the connective tissue between product leadership, engineering, design, and marketing - so that each function has what it needs to do its best work
- Maintain a log of user-requested features and proactively notify users when their requests ship

About You
You’re a Product Manager who thrives at the intersection of strategy and execution. You care deeply about shipping well-defined, high-quality features, not just managing a backlog.

You take pride in closing the gap between “good enough” and “done.”
We value ownership, accountability, a bias to action, and have a culture of feedback. As such, you should be a high-agency individual with self-awareness who wants TransitionZero to win. In addition to seeking out people with a proactive, problem-solving attitude and an eye for detail, as an evolving organisation, collegiality and empathy for our coworkers is a requisite.

To be successful you need to have a high degree of adaptability and willingness to approach challenges with creativity and curiosity. Essentially you need to embrace change and be able to stay focused on our long-term mission while delivering value incrementally, so we can build towards our future.
