Descripción del empleo

What if you could inspect an offshore gas platform, a dam or a city’s water network without leaving your desk?

That’s what Trendspek does. Its platform turns real-world infrastructure into high-fidelity 3D digital twins, so engineers can inspect, annotate and report on critical assets from anywhere. Customers include Chevron, Woodside and Sydney Water. Off the back of a Series A led by OIF Ventures, Trendspek is now scaling the platform to many more customers and building smarter insights on top of it.

That’s where you come in.

The opportunity

Trendspek is hiring a Senior Backend Engineer to own the engine room of the platform: a multi-tenant, security-sensitive SaaS product built on Laravel, MySQL and Postgres, running on containers in the cloud. You won’t just be closing tickets. You’ll make the architecture calls that take the platform to many more customers, and you’ll set the bar for how backend code gets designed, reviewed and shipped.

What you’ll work on

• Moving legacy server-rendered views to clean, well-tested APIs the frontend team will love building on
• Multi-tenant data architecture and query performance at scale
• Security and privacy built in from the start: auth, PII handling, pen-test fixes
• Safe, repeatable releases: migrations, rollbacks and CI/CD
• Observability that catches problems before customers do
• The data and API layers behind Trendspek’s AI insights and assistant products
• Technical direction and code review that raises the game for the whole team, including offshore engineers

You’ll thrive here if you have

• Strong commercial PHP and Laravel experience, or deep experience in a comparable backend framework and a genuine appetite to go all-in on Laravel
• Real database chops: schema design, indexing, query optimisation and migrations that don’t wake anyone up at 2am
• Experience designing and evolving REST APIs for a real product
• Experience with multi-tenant SaaS and the trade-offs that come with it
• A security-first, test-first mindset: you think about failure modes, not just the happy path
• AI tools like Claude Code, Cursor or Copilot as part of your daily workflow, plus a sharp view on where human judgement still has to lead
• The communication and autonomy to drive work and bring people with you

Bonus points for

• Deep Postgres knowledge (pgvector or RAG)
• Experience running containerised workloads in the cloud (Docker, AWS), CI/CD and infrastructure as code
• Experience with queues, background jobs and scaling a monolith
• Experience building AI-enabled product features (LLM integration, retrieval, text-to-SQL).
• Working familiarity with Python or frontend skills
• Exposure to compliance-driven environments (ISO 27001 or SOC 2 experience)
• Experience with geospatial or large-file data (point clouds, 3D assets, tilesets)

Why you’ll love it

Real ownership and a short path from idea to production

AI-assisted engineering built into how the team works every day

Work that matters: your code helps keep dams, pipelines and water networks safe

Hybrid working from Haymarket

A tight interview process with fast feedback, including a hands-on session where using AI is expected
