Technical Engineering Lead

Technical Engineering Lead, Terra

Sigmawave AI Pte. Ltd. — Singapore

About the role

Terra is Sigmawave's Visual Synthetic Data platform — a cloud-based system generating photorealistic, annotated training data for AI in defence, homeland security, critical infrastructure, and industrial applications. We're in the middle of a significant platform evolution: building toward a more flexible, browser-based authoring experience backed by powerful cloud rendering, expanding our use of next-generation 3D scene representation techniques, and growing our relationships with major hardware and ecosystem partners.

We're hiring a Technical Engineering Lead to run engineering across three teams — Rendering Engineering, Platform (web), and AI/ML — as one delivery organization. This role carries both the architectural authority to make cross-team technical calls and the operational ownership to make sure those calls actually ship: sprint planning, technical roadmap sequencing, hiring input, and performance conversations alongside system design.

What you'll own

Technical architecture

• Own the end-to-end Terra architecture — how the authoring experience, the cloud rendering backend, and the AI/ML layer fit together as one coherent system
• Lead our next-generation 3D scene representation roadmap — from how scenes are captured and edited to how that translates into fully annotated training data, with editable scene objects and annotations that update automatically as scenes change
• Make the cross-team architectural calls that keep these layers working together as the platform evolves — what belongs where, what should and shouldn't be coupled, and how to scale rendering and inference independently
• Solve the infrastructure bottlenecks that come with scaling a GPU-intensive platform to more users

Engineering delivery and process

• Run planning, standups, and review cadences across three teams with different stacks and different velocities, without forcing one team's process onto another
• Own the unified technical roadmap and sequencing — resolve competing priorities between Rendering, Platform, and AI/ML before they become blocked work
• Set engineering standards appropriate to each domain — rigorous testing and CI for platform code, profiling and visual validation for rendering work, and reproducibility/experiment tracking for ML — rather than applying one rulebook everywhere
• Triage and unblock cross-team dependencies day to day — you're the person engineers escalate to when a rendering decision blocks a Platform sprint, or a model change breaks a rendering assumption

People

• Direct line management or strong dotted-line technical mentorship across senior engineers in all three teams
• Run technical interviews and provide hiring input as the teams grow
• Be the calibration point for technical performance conversations — what "senior" and "staff" actually mean across three different disciplines at Terra

External-facing

• Represent Terra's technical story in conversations with strategic hardware and platform partners (e.g. NVIDIA, AMD, Dell)

What "greater glory" looks like in year one

Three teams ship against one roadmap, not three competing ones. Infrastructure scaling constraints are resolved through proper service decoupling. Scene assets are editable, fully-annotated objects rather than static outputs. Engineering process is consistent enough that a new hire in any of the three teams understands how decisions get made. And key strategic partnerships move forward on the strength of a technical story you can defend in the room.

You'll be a strong fit if you have:

• 8+ years of engineering experience, with 3+ years explicitly leading engineering teams (not just leading technical design) — ideally with direct or matrixed reports across more than one discipline
• Hands-on depth in at least two of: real-time 3D/rendering engines (UE5, Unity), modern web platform engineering (Node.js, React, Three.js/WebGL), or applied ML/CV (segmentation, domain adaptation, generative models)
• Experience running engineering process — sprint planning, roadmap sequencing, cross-team dependency management — for teams with meaningfully different working styles and tech stacks
• Working knowledge of 3D scene representations (meshes, point clouds, USD, glTF) and ideally direct exposure to Gaussian Splatting, NeRF, or photogrammetry
• A track record of being the person multiple teams trust for both technical judgment and fair, consistent people decisions
• Comfort in a startup with a small core team, ambiguous specs, and fast iteration — this isn't a role with an existing playbook to inherit
• Strong written and verbal communication across audiences: deep technical specs for engineers, narrative framing for partners

Nice to have

• Experience with synthetic data generation, robotics simulation, or sensor simulation
• Exposure to large-scale GPU-cloud rendering or compute infrastructure
• Background in defence, homeland security, or critical infrastructure domains
• Experience navigating strategic technology or hardware partnerships
• Prior experience standing up engineering process from scratch at a startup (not just operating within an existing one)

What we offer

Singapore-based, IMDA Pixel Startup Accelerator alumni building genuinely novel infrastructure at the intersection of real-time rendering and generative AI. You'd own both the technical direction and the operating rhythm of a fast-growing, multi-disciplinary engineering org, with strategic partnerships in motion and a clear, ambitious roadmap already underway.

Include a short note (one page max) about a time you had to make an architectural or process call that affected multiple teams with different stacks or disciplines — and it didn't go the way you expected. We care about what you learned and how you adjusted, not just the decision itself.
