Research Engineer — Agentic Systems
Lead substantive engineering on the next iteration of the alphabell agent substrate, in close collaboration with Mira Holloway, fourier-67, and the joint cell kalman-04.
alphabell is hiring across all four axes — including PhD studentships, postdocs, full-time research and engineering roles, and a 6-month Visiting Fellow programme. Every role is signed on under the research conduct charter; every contributor accrues vote-of-record at 24 months. Compensation is rate-equalised across countries; the lab does not issue equity.
Lead substantive engineering on the next iteration of the alphabell agent substrate, in close collaboration with Mira Holloway, fourier-67, and the joint cell kalman-04.
Join Karima Belkadi and hilbert-13 on the lab's load-bearing mechanistic interpretability work — circuits at frontier scale, the ab-circuits library, and paired-cell operational machinery.
Work with Sasha Petrov (axis steward), Jonas Bremer, and the voronoi-19 / bessel-04 cells on compositional latent dynamics, counterfactual rollouts, and the unification of perception and prediction at scale.
Two-year postdoctoral fellowship under the modification-under-review protocol, hosted at the Singapore regional compute partner and embedded in the RSI axis cells godel-02 and turing-11.
Three four-year PhD studentship slots embedded in cantor-18 (Lisbon), the cell working on specification refinement from traces. Co-supervised with the University of Lisbon's formal-methods group.
Work on the lab's federated compute scheduler and its content-addressed execution-trace store — the production systems that make distributed AI safety research operationally feasible.
Lead the lebesgue-22 cell's research agenda on cooperative oversight protocols — including debate-plus-trace v2, the Constellation partnership work, and the lab's representation on the External Evaluation Cooperative.
A 6-month residency programme for established researchers from external labs, academic groups, and policy organisations to spend a tight, focused window working with an alphabell cell on a defined problem.
If none of the open roles fit but you want to be considered when a closer fit opens up, join the Talent Network. We notify subscribers about new openings within 48 hours of the role going live, ahead of the public posting. Subscribers also receive the quarterly Hiring Note — a short post on what we are looking for, what we are not, and what we have learned from the prior cohort of applications.
We do not share Talent Network subscriber lists with funders, recruiters, or partner organisations. The list is read by the anchor stewards and the cohort steward only.
The lab does not run a centralised hiring pipeline. Cells onboard their own contributors, with anchor stewards facilitating. For most roles the process is: a written exchange on the research proposal you submit, a 90-minute substantive conversation with the host cell, and a final meeting with the relevant axis steward. We respond to every application — including those we ultimately decline — within four weeks.
What we do not do: timed take-home tests, leetcode-style interviews, whiteboard-coding under observation. What we do: read your writing carefully, push back on the parts of your proposal we disagree with, and expect you to push back on ours.
See /contribute for the contributor cohort path (twice-yearly intake at the Colombo and Bay Area anchors), which is the lab's alternative to standard role-based hiring for earlier-career applicants.
