Job description

About

Sampura Research is an AI safety research non-profit focused on scalable oversight for frontier models through improved human/AI “judges”.

Judges (LLM, human, or a hybrid) are essential for aligning highly capable models through their use in evaluation and training. Limitations in today’s judges can lead to undesirable behavior such as reward hacking in training, or failure to spot misalignment in evaluation. As models become more capable and their data more complex, often beyond what the systems overseeing them can understand, we expect these limitations to grow in severity and to become harder to notice.

We are designing novel judge protocols which leverage the strengths of both humans and models to outperform either alone, and building high-quality evaluations to explore judge performance across a diverse set of safety-related tasks. We believe that our focused approach will rapidly advance the science of judges by providing a much-needed systematic measurement of which protocols actually work, and producing state-of-the‑art judges which can be used in real world training and evaluation pipelines.

Backed by an $11M grant from Coefficient Giving ($7M for the first year, and another $4M pledged), Sampura Research was founded in 2026 by members of DeepMind’s alignment and human data teams.

Please see our announcement for more information.

Role Overview

As a founding Member of Technical Staff, you will help shape the research and engineering direction alongside the founding team, and own end‑to‑end research and engineering problems within our agenda:

Evaluation : Build diverse and high‑quality evaluations for judge protocols by pulling from existing datasets/literature and creating novel datasets from scratch.

Methods : Research and implement strategies for improving judge performance through hybridization, such as learning‑to‑defer, human assistance, or other mechanisms.

Infrastructure : Build the tools required to enable and scale our research agenda, including large‑scale inference/evaluation pipelines, a human rating platform, and a robust public leaderboard.

We’ve budgeted roughly $1M per quarter for compute and human data, across a team of fewer than ten, to ensure that we can commit to ambitious goals in all of these areas. You’ll scope ambiguous problems independently, communicate progress clearly, and synthesize findings into papers, blog posts, and benchmark releases.

Staff hires may also lead research and mentorship programs through paid fellowships or volunteer research focused on evaluation or methods work.

If our work and mission resonate with you, please consider applying even if you don’t tick every box. We strongly believe in investing in excellent people regardless of prior or formal experience.

You may be a good fit if you have

• A Bachelor’s degree or higher in Computer Science, Mathematics, or a related field or equivalent experience.

• Proficiency coding in Python or similar languages, as well as machine learning and analysis tooling (e.g., JAX, PyTorch, Pandas).

• Experience working with large language models, human‑in‑the‑loop data annotation systems, or AI evaluation frameworks.

• A willingness to embrace AI tools intelligently, applying scrutiny and human review where necessary.

• A track record of exploring and resolving open‑ended research questions with rigor, in academic or industry labs, fellowships, or volunteer research programs.

Outstanding candidates will have

• Demonstrated ownership across multiple parts of the AI research lifecycle (experiment design and execution, infrastructure, data collection and processing, inference).

• Expertise in a highly relevant domain such as model confidence/calibration, interpretability, safety/alignment evaluation, human‑computer interaction, or other fields related to scalable oversight.

• Hands‑on experience with post‑training methods such as reinforcement learning, adversarial fine‑tuning, or distillation, especially applied to judges or reward models.

• Leadership as a mentor or team lead for related research, either inside a research lab or via programs like SPAR, MARS, or MATS.

Salary Range:

Junior hires: £100,000‑£150,000 (~$136,000‑$205,000)

Senior hires: £150,000‑£200,000 (~$205,000‑$273,000)

Staff hires: £200,000‑£290,000 (~$273,000‑$395,000)

*Approximate USD conversion as of 24 August 2026.

Exceptional students/new‑grads and early‑career individuals will often come in at the junior level. Researchers or engineers with several relevant years of experience will often come in at the senior level. Staff hires typically bring deep expertise in a directly relevant area at notable research labs, and have led research programs or teams.

We’ll agree a target level with you early in the process, and may reassess as you progress.

Logistics:

Location: This role is based on‑site in London.

Visa Sponsorship: We offer visa sponsorship for this role.

Start Dates: We are hiring ~2 FTEs targeting a late‑September 2026 start, and ~2 more starting January 2027. We will continue hiring more FTEs later in 2027.

Equal Opportunity:

Sampura Research is an equal opportunity employer. We are committed to building a team with diverse backgrounds and perspectives and believe this makes our research and workplace better. We do not discriminate on the basis of race, religion or belief, sex, sexual orientation, gender reassignment, age, disability, marriage or civil partnership, pregnancy or maternity, or any other protected characteristic.
