   <strong>
    About the role
    <br/>
    <br/>
   </strong>
  </u>
 </p>
 <p>
  The AI Engineer is the build engine of our AI practice. You turn business requirements into working AI solutions, fast, using coding agents and frontier models, then take the ones that prove their worth into production with the security, compliance, and reliability that enterprise clients demand.
  <br/>
  <br/>
 </p>
 <p>
  This is not a model-training role. We are not building or fine-tuning models from scratch. You build agentic workflows and LLM-powered applications on top of frontier models, wire them into real enterprise systems, and make them safe to run.
  <br/>
  <br/>
 </p>
 <p>
  You will work as part of the delivery team alongside consultants, business analysts, and architects. The consultant carries the client relationship and the architect owns the hard architectural calls. You own the build and you make real engineering decisions, not just execute someone else&rsquo;s spec. You are proactive about spotting better ways to build, and trusted to deliver without close supervision.
  <br/>

 <br/>
 <br/>

 Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.
 <br/>
 <br/>
 <strong>
  The role
  <br/>
  <br/>
 </strong>
 This isn't another AI startup building a chatbot. This is a company acquiring profitable, mission-critical B2B SaaS businesses, then deploying a proprietary AI operating system across them. The goal: encode operational knowledge, automate workflows, and compound intelligence across a growing portfolio. The founding team brings deep experience from early-stage, pre-IPO Palantir and frontier AI research.
 <br/>
 <br/>
 You'll join a small engineering team tackling genuinely hard problems. This is end-to-end ownership: from architecture to production. It's not about maintaining legacy systems or shipping minor features. You'll build the core platform that ingests everything from CRM to financial records, or you'll deploy forward into acquired companies, shipping product changes identified by the intelligence layer. You'll shape what gets built, working directly with product and commercial teams. This is a rare seat for an engineer who wants to build, not just code.
 <br/>
 <br/>
 <strong>
  The work
  <br/>
  <br/>
 </strong>
 <ul>
  <li>
   Take end-to-end ownership of features, from architecture design to production deployment.
  </li>
  <li>
   Design APIs, data models, and integrations in Ruby and Python to ingest structured and unstructured data from acquired companies.
  </li>
  <li>
   Build React interfaces that surface real-time operational intelligence and enable autonomous agent workflows.
  </li>
  <li>
   Work directly with product and commercial teams to define and shape the core platform or forward-deployed product changes.
  </li>
  <li>
   Deploy product changes into group companies, acting on insights identified by the AI intelligence layer.
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
  What You Bring
  <br/>
  <br/>
 </strong>
 <ul>
  <li>
   2-5 years of experience building and shipping production systems, owning the full lifecycle (data modelling, API design, testing, reliability, deployment).
  </li>
  <li>
   Strong in at least one modern stack, with the ability to quickly pick up new languages (the codebase is 90%+ Ruby).
  </li>
  <li>
   A track record of breaking down ambiguous problems, prioritising high-leverage work, and communicating technical reasoning clearly to non-engineers.
  </li>
  <li>

Software Engineer (up to £150k)

Apple

<p>The Private Cloud Compute (PCC) team builds Apple's privacy-preserving cloud inference platform - the system that lets generative-AI features on iPhone, iPad, Mac, and Vision Pro reach into the cloud without compromising user privacy. We are looking for a Software Engineer to join the team that builds the on-device client side of that pipeline: the system frameworks and sandboxed services that every Apple Intelligence and Foundation Models request flows through before it ever leaves the device.<br>
<br>
This is system-level Apple platform work. You will design and ship the Swift frameworks that turn high-level inference requests into a compact wire protocol, manage long-lived connections, stream multimodal output back to client apps - all under strict process isolation and privacy guarantees. Your code will run on every device that uses Apple Intelligence - and the bar for correctness, performance, and privacy is set accordingly.<br>
<br>
<b>Description</b><br>
You will be a key contributor to the Swift frameworks and XPC services that connect on-device apps and system daemons to PCC. Day-to-day responsibilities include:<br>
<br>
Designing and evolving the on-device client SDKs and the XPC services they sit behind, balancing API ergonomics for client teams with the strict process-isolation and attestation guarantees required by PCC.<br>
Implementing high-throughput, low-latency request paths: protobuf serialization of inference payloads, payload compression, multi-turn session state and lifecycle, retry/cancellation semantics, and streaming of incremental model output back to clients.<br>
Owning concurrency and resource management across async/await, AsyncStream, and GCD - including correct cancellation, back-pressure, and lifetime management of long-lived XPC connections.<br>
Building the telemetry, signposts, and privacy-audited logging that let on-call engineers diagnose request failures across device, cloud, and inference layers without exposing user data.<br>
Collaborating closely with the PCC server-side, Foundation Models, attestation, and platform-frameworks teams; writing design documents, leading reviews, and mentoring engineers on Apple platform fundamentals.<br>
Profiling on real hardware with Instruments and driving down memory, latency, and energy costs in the request path - these libraries run on every device, on every inference, so every microsecond matters.<br>
<br>
<b>Preferred Qualifications</b><br>
Experience designing or evolving wire protocols (e.g., Protocol Buffers), data-streaming pipelines, or connection management.<br>
Hands-on experience with Apple's Inter-Process Communication (XPC) to bridge sandboxed applications and system services.<br>
Familiarity with secure communication protocols, cryptography, or privacy-preserving architectures.<br>
Working knowledge of ML concepts and frameworks and proficiency in performance profiling with Instruments, and experience implementing robust client-side telemetry and logging using native Apple APIs.<br>
Familiarity with end-to-end systems that span device, network, and server tiers, and comfort reasoning about failure modes across that boundary.<br>
<br>
<b>Minimum Qualifications</b><br>
Experience developing complex, system-level frameworks, daemons, or background services for iOS and macOS (beyond standard UI-focused app development).<br>
Strong programming proficiency in Swift, alongside experience with Objective-C or C/C++ for lower-level system integration.<br>
Deep understanding of concurrency (Swift Concurrency, GCD), memory management, and asynchronous network programming.</p>

Using a blend of cutting-edge and bespoke technologies, including internally developed systems you wont find elsewhere, youll solve complex, mission-critical challenges.</p><p>
This is an engineering-led role where youll play a key part in delivering and managing infrastructure through code, operating in fully code-driven environments. Using tools such as Kubernetes, infrastructure as code and automation frameworks, youll develop and manage production environments that support operational activity. Youll oversee deployments end to end, manage upgrades and changes, and ensure systems remain stable and available without disruption, maintaining continuity of service.</p><p>
Monitoring is central to the role. Youll track system health, performance and behaviour using logs and metrics, identifying risks and weaknesses before they impact service. When issues arise, youll investigate root causes and contribute to improvements that strengthen reliability and prevent recurrence.</p><p>
Day to day, youll work closely with engineers, developers and researchers to deploy new capabilities and improve existing systems. Youll collaborate with monitoring teams to respond to system concerns and ensure environments remain secure and resilient. Alongside this, youll contribute to improving how systems are managed, refining processes and strengthening reliability practices as systems evolve.</p><p>
