Senior Product Manager

ABOUT APHEX

We're the construction planning platform replacing outdated spreadsheets with multiplayer tools that delivery teams love. Major contractors like Acciona, CPB Contractors, John Holland, and McConnell Dowell use Aphex to deliver projects from £50 million to multi-billion pound mega projects.

We're market-leading in Australia and the UK, supporting teams building the roads, rail, tunnels, and hospitals that millions use every day. Our founding thesis: owning the planning layer is a gateway to solving high-friction adjacent processes in what we call the orchestration layer of major project delivery.

THE ROLE

We're looking for a Senior Product Manager to own our Insight & Data area — the measurement layer of the Aphex platform. You'll report directly to the Head of Product and lead a squad of ~6 engineers that flexes with scope.

The opportunity: Aphex captures something unique — granular, structured data about how major projects actually execute. Not just what was planned, but the daily record of what happened: coordination, progress, constraints, the gap between plan and reality. This dataset doesn't exist anywhere else at this fidelity.

Our thesis is that the behaviours teams run — publishing cadence, daily coordination routines, statusing discipline — are the leading indicators of project performance. Measuring those routines, scoring them, and connecting them to outcomes is the core intellectual problem of this role. Nobody in construction has done it.

Your two customers:

1. The user. Signals surfaced inside their existing workflow that change behaviour on site — not another dashboard. A routine-health score a project team actually acts on. Org-level insight an executive trusts.
2. Aphex itself. Your measurement system is the evidence layer for our own product decisions — activation curves, feature landed-vs-rejected, routine adoption. Success looks like every PM in the company citing your measures in their briefs without having to ask you for a report.

Your charter — what you own:

• The core measures: the canonical, tool-agnostic definitions of project and user behaviour (publishing scores, daily-cycle activity, routine health) and the taxonomy underneath them
• The data platform: the pipelines and aggregated data models everything reads from
• MCP and the API surface: how customers and AI tools access their data
• Eval frameworks for the AI agents that consume this data
• The org/admin surfaces: admin console, org-level insights, report sharing, request-access — end-to-end, your team ships these
• Activation as an outcome: instrumenting and driving the behaviours that make projects stick

Explicitly not yours:

• The daily-cycle workflow itself (briefings, capture, diary) — owned by the Planner and Diary teams
• In-workflow rendering of your signals — you own the signal contract (what's measured, what triggers, what good looks like); the surface teams build the moments, prioritised like any other roadmap work

That split is deliberate. This is a leverage role: your definitions and data flow through every team's roadmap.

WHAT YOU'LL DO

Own the measurement system

• Define, defend, and version the core measures of project behaviour and performance
• Connect behavioural routines to outcomes — build the evidence for what actually predicts delivery
• Make the measures self-serve for users, customer teams, and internal product/GTM teams

Own delivery

• Run discovery through QA to launch with your engineering team
• Write specs and briefs your team can execute against — and hold them to their briefs
• Independently sanity-check sequencing and estimates; challenge what doesn't smell right
• Make daily trade-off calls on scope, timeline, and quality

Own the platform

• Data pipelines, aggregated models, and the API/MCP access layer
• Platform reliability — major projects depend on accurate, accessible data

Partner across the company

• Publish signal contracts the Planner and Diary teams build against
• Work with CS and Solution Engineers on how customers want to use their data
• Feed product decision making across the org with evidence, not opinion

WHY THIS MATTERS

Every contractor reinvents reporting from scratch, and every construction analytics product measures the same lagging outputs. Aphex's edge is measuring the behaviours that precede the outputs — and we have the only dataset that makes it possible. You're building both the product that surfaces this to customers and the evidence engine that steers what Aphex builds next.

ABOUT YOU

Essential:

• A measurement background: you've defined metrics systems, built or evaluated data pipelines, or worked as/with data scientists closely enough to hold your own
• Senior product ownership: you've owned a product or platform area standalone — set direction, not just executed someone else's
• Technical depth to interrogate, not just converse: you can pressure-test an engineering estimate and spot a sequencing error
• Track record shipping data products, analytics, or platform work with quality
• Remote-first operator: writes clearly, documents decisions, communicates proactively

Highly valued:

• Behavioural analytics, activation/retention instrumentation, or product-led growth measurement
• Experience with AI/agent products and evaluation frameworks
• Vertical SaaS or construction/industrial experience
• Experience making internal teams evidence-driven, not just customers

This role isn't:

• A dashboard factory — we're building signals into the workflow itself, not another reporting surface, so it won't suit someone who wants to just ship charts
• Pure strategy — this is hands-on delivery; you'll need to enjoy owning execution, not just setting direction and handing it off
• Diluted by a layer above you — you'll report straight to the Head of Product, so the ownership is genuinely yours
• A role where the brief always arrives fully resolved — you'll often be deciding with incomplete information, and that's part of the challenge: shaping the answer, not just executing one that's already settled

What We Offer

1. Flexible/remote work across UK and Australian time zones, with WeWork access
2. One annual all-expenses-paid international team offsite (we've been to Vietnam and Thailand — where to next?)
3. An Aphex social budget
4. £500 annual training allowance and access to our Emerging Leaders programme
5. Paid parental leave
6. MindFi EAP access
7. Employee Referral Program
8. Your personal Lego welcome kit & Aphex swag
