Technical Engineering Lead

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.

Responsibilities

• 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
• 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

Requirements

• 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 infr
