About the Project:

Our client is a UK-based fintech company building and scaling financial services used by hundreds of thousands of businesses. The team focuses on developing secure, reliable, and highly scalable backend systems that power critical financial operations. This role offers an opportunity to work on complex distributed architectures, high-volume transaction processing, and modern cloud-native technologies in a fast-growing product environment.

What We Do

Ten8 builds AI-native automation for freight logistics — a voice agent for carrier calls and rate negotiation, and an email pipeline for load board posting and compliance. Both are live, both are generating revenue, and both need a product owner.

Why This Role

Voice AI and freight automation are among the fastest-moving areas in enterprise software. This is a high-visibility initiative with paying customers already on it. Whoever takes this role will own what gets built and why — shaping production AI products from discovery to delivery while the team around them handles the domain expertise and the technology.

The Role

The initiatives are already running. The freight expertise and AI stack are already on the team. What’s missing is someone to own the product — to run discovery, define scope, and turn customer pain into clear requirements and measurable outcomes.

• Own product discovery: customer interviews, pain mapping, expectation management
• Define MVP scope and success metrics before engineering starts building
• Own the backlog — prioritize, write clear requirements, maintain specs, communicate trade-offs
• Drive “what to build next” from customer feedback, usage data, and business goals
• Partner with engineering through our agentic SDLC: discovery → design → implementation → verification
• Run customer development sessions and validate direction before committing build capacity

What You’re Walking Into

• Discovery is our biggest challenge. Engineers are strong technically, but scoping work with customers needs reinforcement. That’s your first project.
• No tight loop yet from customer pain → requirement → shipped feature → measured outcome. You’ll build it.
• Both voice and email workstreams lack a single product owner who can say “yes, this” and “not yet, that.” That changes when you join.
• You’ll work closely with domain experts (brokers, ops) to extract requirements from a complex, fast-moving industry.

You’re a Fit If

• You’ve owned product at a startup — AI or SaaS background is a plus, not a requirement
• You run customer discovery confidently — ask the right questions, manage expectations, scope MVPs
• You write clear requirements and prioritized backlogs, not vague feature lists
• You think in metrics — conversion, retention, satisfaction — and define success before build starts
• You bring structure to ambiguity without waiting to be told what to do

On Domain Knowledge

No freight, logistics, or AI experience required. The team covers both. What we need is strong product instincts applied to a technical domain — fresh eyes are part of the value.

How We Hire

1. Take-home assignment (~45–60 min) — a real case from our product; we want to see how you think through requirements, priorities, and trade-offs
2. Interview with CTO — case review, product thinking, how you handle ambiguity, background
3. Discovery exercise (~30 min) — live session simulating a customer discovery call. You lead, we play client and domain expert.
4. Offer

No lengthy loops. We move fast.

Role Purpose

This role owns the backend services behind our introducing-broker and partner program: partner onboarding, multi-level partner commission and rebate logic, and the reporting that partners rely on to understand their earnings.

• Build resilient integrations with other backend services across onboarding, payments and reporting
• Design event-driven flows using messaging to keep data consistent across service boundaries
• Handle failure modes, retries and idempotency so financial calculations stay correct under real conditions

Reliability on a Live Financial System

• Treat correctness as a first-class requirement so commission and rebate outcomes are accurate and reproducible
• Instrument services with logging, metrics and alerting to detect and diagnose issues quickly
• Contribute to on-call readiness, incident response and post-incident improvements
• Identify and address performance, scalability and data-consistency risks before they reach production

Engineering Quality and Collaboration

• Write clean, well-tested code with meaningful unit and integration coverage
• Provide thorough, constructive code review and help raise standards across the team
• Maintain and improve CI/CD pipelines for fast, safe and repeatable releases
• Document key decisions, APIs and operational runbooks so the team can move quickly

• Clear communicator who collaborates well asynchronously in a remote team and gives effective code review

Nice to Have

• Experience in trading, brokerage or fintech, especially CFDs/FX
• Familiarity with the MetaTrader 5 platform and its data model
• Experience building partner, affiliate, referral or commission/rebate systems
• Exposure to Kubernetes for orchestrating containerised services
• Experience with observability tooling such as Grafana, Prometheus or CloudWatch
• Familiarity with infrastructure-as-code using Terraform
• Experience working with payments flows such as deposits and withdrawals

About the client
The client is a neocloud building purpose-built GPU infrastructure for AI workloads. We operate large-scale clusters powering training and inference for some of the most demanding AI customers in the market, and we’re rapidly expanding. Our infrastructure runs on NVIDIA and AMD accelerators, InfiniBand and high-speed Ethernet fabrics, and a production stack spanning bare-metal provisioning, Kubernetes, and OpenStack.

We’re small, senior, and moving fast. The people who do well at the client own problems end-to-end and make decisions with incomplete information.

The role
We are hiring an Incident & Reliability Lead to own the incident and problem management programs at the client. This is the person who runs the call when a customer cluster goes down, drives the post-mortem afterward, and hardens the runbooks so the same failure does not surface twice.

This is not an ITIL paperwork role. You will be technically credible across Kubernetes, Linux, networking, and GPU infrastructure, enough to lead a live incident with platform engineers, and a customer on the bridge. But your center of gravity is the process: fast, clean incident response, honest communication, and a relentless feedback loop between customers engineering.

You will set the standard for how the client behaves during our most challenging hours. Done well, this is one of the most visible and highest-leverage roles on the team.

You will work closely with cloud operations, network teams, and customer-facing counterparts. Expect to be on-call in a shared rotation.

What you’ll own

• Incident command. Run major incidents end-to-end: triage, escalation, comms cadence, timeline, decision log, and drive-to-resolution. You are the conductor, not the fixer.

• Customer communications. Own customer-facing incident messaging, initial acknowledgement, status updates at defined intervals, resolution notice, and written RCA. Clear, honest, no hedging.

• Post-mortem and RCA program. Run blameless post-mortems, write the RCA, track action items to completion, and publish learnings across the org. Own the quality bar for RCA writing at the client.

• Escalation framework. Define and maintain the severity matrix, escalation trees, on-call rotations, and paging policies across platform, network, DC ops, and leadership.

• Runbooks and playbooks. Turn tribal knowledge into durable, testable runbooks. Drive the engineering teams to document before the next 2am page, not after.

• On-call health. Own the on-call experience: page volume, alert quality, rotation fairness, and handoff hygiene. Kill noisy alerts. Fix the ones that matter.

• Reliability metrics. Define and report the metrics that matter: MTTA, MTTR, incident count by class, SLO attainment, repeat-offender systems. Make reliability a number the business trusts.

• Game days and drills. Plan and run incident drills across clusters, regions, and customer scenarios. Surface gaps before customers do.

• Incident tooling. Own the incident tooling stack, paging, status page, incident channel automation, timeline capture, RCA templates. Evaluate and land the right tools.

What we’re looking for

Required

• 7+ years in SRE, production engineering, or infrastructure operations, with clear ownership of incident management in at least one prior role.

• Proven ability to run major incidents as the commander, keeping a room calm, driving decisions, managing comms to customers and executives in parallel.

• Strong technical fluency across Linux, Kubernetes, networking (L2/L3, BGP basics), and cloud or bare-metal infrastructure. Deep enough in the stack to challenge assumptions, debug alongside engineers on a bridge call, and senior enough to turn each incident into durable improvements like runbooks, automation, guardrails, so the next incident does not need you.

• Excellent written communication. You can draft a customer-facing RCA that is accurate, clear, and does not over- or under-promise, and do it within the SLA window.

• Experience owning SLOs, error budgets, or equivalent reliability metrics as a working practice, not a slide.

• Experience designing on-call rotations and alerting practices across multiple teams.

• Comfortable operating in a fast-moving, still-forming environment. You write the runbook that did not exist yesterday.

Strongly preferred

• Experience in GPU infrastructure, HPC, or AI/ML platform operations, NCCL, InfiniBand, DCGM, or similar.

• Direct experience with Kubernetes incident response, control plane, CNI, operator patterns, noisy-neighbor debugging.

• Experience interfacing with neocloud, enterprise or hyperscaler customers during live incidents.

• Familiarity with Prometheus, Checkmk, Grafana, and modern incident tooling (OpsGenie/JIRA).

• Prior experience at a neocloud, CSP, or infrastructure vendor where downtime had direct revenue impact.

How we work

• We’re remote-first across US, LATAM, and EU time zones with a strong operational culture.

• We use AI tooling heavily in day-to-day operations and expect everyone on the team to be fluent with it and to help us get more leverage from it.

• We ship, we debug, we iterate. We don’t process-engineer our way around problems that need to be solved.

• We value written artifacts, RCAs, runbooks, design docs, over meetings. We value calm over performative urgency. We protect focus time and we protect sleep.

AI as a force multiplier

The client runs the infrastructure that powers the AI economy. We expect our team to use AI aggressively in how we work. For this role specifically, that means using AI to draft RCAs faster, triage logs and metrics during incidents, summarize timelines, generate customer-facing communications from raw incident data, and turn post-mortems into runbook updates automatically. If you have not yet built this into your workflow, you will here.

What success looks like

First 30 days

• Shadowed on-call rotations across the platform, network, and ops teams.

• Read every RCA written and identify the top three recurring failure classes.

• Met with the top three customers and understood their incident expectations and SLA terms.

• Documented the current-state incident response process, gaps and all.

First 90 days

• Published a revised severity matrix, escalation tree, and customer-comms cadence, adopted across teams.

• Run at least two major incidents as commander with clean timelines and customer comms.

• Delivered a new RCA template and coached the team through at least three post-mortems against it.

• Stood up baseline reliability metrics (MTTA, MTTR, incident count by class) with a weekly reporting cadence.

• Killed at least 20% of current alert volume by eliminating low-signal pages.

First 12 months

• The client has a mature, documented incident management program that a new customer can diligence with confidence.

• Repeat-offender incident classes are down materially, with clear attribution to runbook, tooling, or engineering changes you drove.

• Customer-facing RCAs are consistently delivered within SLA and are referenced by customers as a differentiator.

• On-call health (page volume, rotation fairness, engineer-reported burden) has measurably improved.

• Game days are a regular cadence and have surfaced and closed real gaps before they became customer incidents.
