Job description

Computer Vision & Backend Engineer (60-Day Build)

Company : WowNom

Type : Fixed-term contract (60 days, full-time) — extension possible

Location : Remote (Singapore Time, APAC-friendly hours)

How to apply

Email hello@wownom.com with subject “60-Day CV & Backend Build — WowNom” and include :

  • A shipped CV project (repo / demo) + one latency and one accuracy number you achieved and how
  • Availability to start within 1–2 weeks and timezone
  • (Optional) A brief note on grams estimation from depth vs. monocular on plated dishes

Mission (60 days)

Deliver a production-ready photo recognition system that powers a calorie-counting app end-to-end :

  • Upload → Analyze → Nutrition : From a food photo, return { name, grams, confidence, tags, ingredients, macros } per item, with meal totals and remaining daily targets.
  • Retraining option : Design and ship the infrastructure that learns from user corrections (renames, grams / macros edits) and can retrain / evaluate safely.
  • What you will build (end-to-end scope)

  • Public APIs
  • POST / api / vision / upload (multipart JPEG / PNG / WebP) → { name, grams, confidence, tags }[]
  • POST / api / coach / photo → persist image, call vision, run lookupFood, return items, meal totals, remaining Daily, and coachReply
  • Food analysis (multi-cuisine)
  • Gate + Instances : YOLOv8 / 11 detect (food vs distractors) → YOLO-seg (retina masks)
  • Naming : SigLIP / CLIP (or compact ViT) on mask crops, synonyms / taxonomy aware
  • Safety : OOD detector + low-confidence suggestions; safe abstain (no hallucinations)
  • Portioning (grams)
  • Device-depth first (if present), monocular fallback (MiDaS / ZoeDepth), tabletop plane-fit, coverage %, density lookup (Redis), portion_source=device|mono|heuristic
  • Nutrition & ingredients
  • Map labels → canonical taxonomy (≤400 dishes)
  • Query our nutrition DB or external sources (e.g., FDC) to assemble ingredients + per-ingredient macros, scale by grams, compute meal totals
  • Retraining loop (feedback → model)
  • Capture user edits & low-margin / OOD crops → store to ClickHouse / S3
  • Scripts & jobs to rebuild datasets, fine-tune, evaluate with metric gates, and publish new artifacts safely
  • Ops & safety
  • CI evaluator (Top-1 / Top-5, OOD FP rate, Portion MAPE, latency SLOs) that blocks regressions
  • Observability : structured logs, per-stage ms, model / taxonomy versions
  • Privacy : consent gate, retention / “delete my images” flow
  • 60-Day milestone plan (acceptance-driven)

    Week 1–2 (Foundation & API)

  • Stand up GPU FastAPI / infer-v2 + Node / api / coach / photo
  • Return stubbed payload matching contract; basic telemetry; dockerized
  • Demo : curl upload → JSON schema exactly matches app contract
  • Week 3–4 (Models & Portions)

  • YOLO gate+seg (export ONNX); CLIP / SigLIP naming with temperature scaling
  • Depth-aware grams (device depth) + mono fallback; density via Redis
  • Demo : multi-cuisine sample set returns names + grams within sanity bounds
  • Week 5 (Nutrition & Safety)

  • Taxonomy (≤400) + nutrition mapping (our DB / FDC)
  • OOD abstain with suggestions; ingredients + per-ingredient macros scaled by grams
  • Demo : App-ready payload { name, grams, confidence, tags, ingredients, macros } per item; meal totals & remainingDaily
  • Week 6–8 (Retraining + CI gates + Canary)

  • Feedback capture from user edits; dataset rebuild scripts; fine-tune path
  • Evaluator + CI gates (json report) and shadow / canary rollout toggles
  • Privacy & retention wired; runbook + handover docs
  • Final Demo (Day 60) : end-to-end flow on staging GPU; retrain on a small corrected set; CI passes; canary toggle ready
  • Success metrics (set at kickoff; used by CI gate)

  • Quality : Top-1 on core ≥ target; OOD FP ≤ target; Portion MAPE ≤ target on depth images
  • Latency : p50 ≤ 350 ms, p95 ≤ 800 ms on our staging GPU
  • Reliability : CI gate prevents regressions; logs / metrics complete; consent & retention enforced
  • Minimum qualifications

  • Shipped computer-vision systems to production (beyond notebooks)
  • YOLO detect / seg training or fine-tuning; export to ONNX / TensorRT and debug opsets / dynamic shapes
  • CLIP / SigLIP or ViT classifier work (fine-tune + temperature scaling); OOD thresholding
  • Depth pipelines (device + monocular), geometric reasoning (plane fitting, coverage)
  • Production APIs (FastAPI / Node), Redis / ClickHouse (or similar), Docker, GitHub Actions
  • Obs / ops : structured logging, latency profiling, privacy / retention patterns
  • Nice-to-haves

  • Triton Inference Server, FAISS / ANN, K8s / Helm, W&B / MLflow
  • Nutrition data integration (FDC or equivalent), taxonomy design
  • Tech you’ll touch

    PyTorch, Ultralytics YOLOv8 / 11, SAM / SAM2, SigLIP / CLIP, MiDaS / ZoeDepth, ONNX Runtime (CUDA EP), TensorRT (nice), FastAPI, Node / Express, Redis, ClickHouse, Docker, GitHub Actions.

    What we provide

  • GPU access (cloud, H100 / A10 / T4), seed datasets & taxonomy draft, staging infra, and rapid product feedback
  • Clear API contract and benchmark packs for CI gating
