About the role
The Developer Platform product manager decides what the API, SDKs and agent tooling do next, and writes down why. The users are developers inside and outside Clexerl, and the product is a set of interfaces that must stay stable while the models behind them improve every few months.
Frontier AI keeps adding capabilities, and Clexerl Go exercises them as a demanding first customer. Your task is to turn research progress and developer pain into a roadmap that makes sense: which capabilities become endpoints, which stay experimental, and which deprecations are worth the disruption. Getting the abstraction right is worth more than shipping the feature first.
You work in writing. Specs, decision records and launch notes are the primary tools, and you are expected to disagree with them in public and then commit.
What you’ll do
- Own the roadmap for the API, SDKs and agent tooling, ranking work by developer impact, platform cost and strategic value.
- Write product specs with clear problem statements, non-goals, success metrics and a plan for backwards compatibility.
- Define pricing and usage metrics with finance and engineering, including how new capabilities are metered.
- Run structured developer research through interviews, usage data and support analysis to find where integration breaks down.
- Coordinate launches with research, safeguards, documentation and developer relations, including staged access and evaluation criteria.
- Decide when to deprecate, and manage migrations so customers are never surprised.
What you’ll bring
- Several years of product management on developer products, APIs or infrastructure, with launches you can describe in detail.
- Enough technical depth to read an API design, challenge an architecture and discuss latency or reliability trade-offs credibly.
- Comfort with data: funnels, cohort retention, usage distributions and the limits of each.
- Strong written communication, with specs that engineers actually refer back to.
- Understanding of how language-model products behave, including non-determinism, evaluation and cost per request.
- Judgement about what not to build.
Nice to have
- Experience as an engineer before moving into product.
- Prior work on usage-based pricing or enterprise platform packaging.
- Background in agent frameworks, workflow orchestration or similar tooling.
- Experience managing public deprecation and migration programmes.
Work you might take on
- 01
Define the product shape of long-term memory as an API, including retention controls, scoping rules and how developers inspect what is stored.
- 02
Write the deprecation plan for an early endpoint, with migration tooling, a usage-based timeline and a customer communication sequence.
- 03
Set the success metrics for the agent tooling programme and build the dashboard that tracks time to first working tool call.
- 04
Run a research study on why integrations stall after prototype, and turn the findings into three prioritised platform changes.
