9fin

<div>About 9fin
9fin is the AI platform powering global debt markets &mdash; the world&rsquo;s largest asset class at over $145 trillion.
Debt markets are vast, global, and mission-critical, yet still run on fragmented data, PDFs, and manual workflows. 9fin replaces this broken infrastructure with a single platform that centralises proprietary credit data, deep analysis, and high-value workflows across global markets.
Today, 9fin powers teams at 300+ blue-chip institutions worldwide, including global banks, asset managers, private equity firms, law firms, and advisors. The business is scaling at exceptional speed, with rapid expansion in the US and best-in-class retention driven by deep workflow adoption.
We&rsquo;re at a defining inflection point. With proven product-market fit and strong, global market pull, 9fin is accelerating toward becoming the category-defining platform for debt markets worldwide.<h2 class="jobSectionHeader">
The Opportunity</h2>
We are seeking an Engineering Lead II to lead three customer-facing engineering teams across Onboarding &amp; Activation, Mobile, and Office Productivity.
These teams are responsible for how customers discover, adopt, access, and engage with 9fin across multiple surfaces and workflows. Together they own critical parts of the customer journey including onboarding, permissions and entitlements, activation, notifications, discovery, mobile experiences, and productivity tooling such as Microsoft Office integrations.
You will lead multiple engineering pods (circa 7 engineers total), each with its own product area, roadmap, and technical challenges, while ensuring they operate as a connected ecosystem rather than independent products. Success in this role requires strong organisational leadership, technical depth, and the ability to identify opportunities for shared platforms, reusable services, and common architectural patterns across teams.
This role is ideal for a highly technical engineering leader who enjoys operating across multiple domains, helping teams solve complex architectural challenges, and creating alignment between product strategy, customer needs, and engineering execution.<h2 class="jobSectionHeader">

Senior Software Engineer I – Search and AI Platform

Resolution

<div><h1 class="jobSectionHeader">About Resolution</h1>
Resolution does research on how to align artificial superintelligence (ASI). ASI may be developed in the next few years, but it is unclear whether alignment is on track to be ready in the same timeframe. We aim at higher a priori confidence in aligned outcomes by pursuing a portfolio of theory and empirics bets, any one of which &mdash; if it succeeds &mdash; would meaningfully advance the field. We invest heavily in research automation to accelerate progress, and we believe that stronger alignment theory unlocks higher automation: more principled approaches give us better filters for which directions of automated research are promising.
Resolution was founded in 2026 by researchers from UK AISI's Alignment Team, who ran the &pound;30m Alignment Project, and Timaeus, who pioneered applying singular learning theory to alignment.
For more information, see our announcement.<h1 class="jobSectionHeader">
About the Team</h1>
We are hiring Research Engineers across several main focus areas. We expect the boundaries between these areas to be flexible, but please indicate which mode you're more interested in (or &quot;either&quot;) in your application.
Research Automation (primary focus). A cross-cutting function that builds the infrastructure and tooling our researchers use to scale their work, increasingly leveraging fleets of AI research assistants alongside small teams of humans.
Program-embedded Research Engineering (also hiring). Research engineers embedded within one of our research programs (scalable oversight, complexity theory, learning theory, personas, and possible future programs like heuristic arguments or game theory), partnering with researchers on scaling experiments, building program-specific infrastructure, and translating theoretical insights into empirical tools.<h2 class="jobSectionHeader">
About the Role</h2>
Research Engineers at Resolution are core members of our research teams, directly driving both research and the core infrastructure behind it. We believe clean engineering on automation, experimentation, and infra is essential to ambitious research, and that excellence on this front requires active research participation.<h2 class="jobSectionHeader">
Responsibilities</h2><ul><li>
(Research automation track) Build agentic research infrastructure: experiment orchestration, hypothesis generation, automated analysis pipelines; autoformalization tooling for the theory side; internal AI-powered tools for researchers</li><li>
(Program-embedded track) Scale program experiments to frontier-tier models; build program-specific infrastructure; partner with researchers on engineering and implementation.</li><li>
(Both) Maintain and extend distributed training, experiment, and evaluation infrastructure</li><li>
(Both) Contribute to and maintain shared codebases across the org</li><li>
(Both) Communication of engineering &amp; automation progress, obstacles &amp; learnings to your team and the wider org via Slack and in weekly meetings.</li></ul>
We're on the lookout for excellence, so if you're a cracked engineer who doesn't precisely fit these descriptions, please still apply!<h2 class="jobSectionHeader">
You May Be a Good Fit If You</h2><ul><li>
Have a strong software engineering background, including production-quality Python</li><li>

Have a demonstrated ability to ship complex systems end-to-end</li><li>
Have a Bachelor's degree or equivalent in CS, physics, math, ML, or related</li><li>
Are willing to use AI tools aggressively in your own workflow, with appropriate care to not get fooled!</li><li>
Are motivated by alignment of artificial superintelligence (ASI) and want to contribute to it full-time.</li></ul><h2 class="jobSectionHeader">
Strong Candidates May Also Have</h2><ul><li>
Experience with autoformalization, Lean, or other proof-assistant tooling</li><li>
Background in research infrastructure or ML platform engineering at frontier labs</li><li>
Experience scaling ML systems to 100B+ parameter scale</li><li>
Experience with CUDA kernel development or GPU optimization</li><li>

<li>Translate Cyber Threat Intelligence and threat-hunting findings into robust, high-fidelity detections with low false-positive rates.</li>
<li>Establish, own, and maintain the central detection library, ensuring detections are version-controlled, tested, documented, and mapped to MITRE ATT&amp;CK coverage.</li>
<li>Champion Detection-as-Code, implementing Git-based workflows, CI/CD pipelines, automated testing, and peer review for all detection content.</li>
<li>Define and track detection coverage, efficacy, and quality metrics (e.g. ATT&amp;CK coverage, detection fidelity, time-to-detect) and report on detection posture to senior leadership.</li>
<li>Lead detection validation and tuning through adversary emulation, purple-team exercises, and breach-and-attack-simulation tooling (e.g. Atomic Red Team, Caldera).</li>
<li>Support the integration of AI and automation into detection workflows &ndash; including AI-assisted detection authoring, enrichment, and triage &ndash; and lead detection efforts for AI/GenAI-specific threats.</li>
<li>Partner with SOC, Threat Hunting, CTI, Incident Response, and Vulnerability Management to close detection gaps identified during incidents and hunts.</li>
<li>Govern the full detection lifecycle: intake, development, testing, deployment, monitoring, tuning, retirement, and continuous improvement.</li>
<li>Evaluate and onboard new log sources, telemetry, and tooling to expand detection coverage across the global estate.</li>
<li>Set standards for detection documentation, runbooks, and response guidance so every detection is clear and actionable for the SOC.</li></ul>
