Build the signal layer for on-chain markets.
SpotX is a small, opinionated team building real-time smart-money intelligence for active traders and institutional desks. We hire people who treat AI as leverage, hold a craftsman's bar, and own outcomes end-to-end.
Small team. High leverage.
Every role is expected to use the modern AI stack — Cursor, Claude, Lovable, Perplexity — to move faster. We hire people who ship, not people who prompt.
Whether it's a webhook payload schema or a Twitter post, we sweat the craft. Quality compounds; thin work does not.
Tickets are scaffolding, not assignments. You scope, ship, measure, and own the post-mortem when it breaks.
The visual system team.
Editorial-grade visual system, motion, and product UX. We treat design as a load-bearing wall, not paint.
Senior Brand DesignerSenior · IC Remote (EU / US-East timezone)Full-timeView role+
Own the visual identity of SpotX end-to-end — from product surfaces to investor decks to printed editorial. You'll keep our editorial-light, Dune-meets-Bloomberg system coherent as we scale.
- Evolve the SpotX brand system: typography, motion, illustration, photography direction
- Design marketing campaigns, launch assets, conference materials, and partner co-marketing
- Partner with Product Design on shared tokens, iconography, and signature moments
- Maintain the brand guidelines doc, asset library, and template kits
- Direct freelancers, illustrators, and motion designers for one-off campaigns
- Editorial layout & typographic hierarchy (Newsreader / Instrument Serif sensibility)
- Motion principles and timing (Lottie, After Effects, Rive)
- Color theory in production — HSL token systems, accessibility contrast
- Strong written rationale for design decisions
5–8 years, ideally including one fintech / data-product brand build
Use Midjourney / Sora / Runway for moodboards and motion R&D, but ship in deterministic tools. AI is for ideation velocity, not final pixels.
Product Designer (Data UX)Mid–Senior · IC Remote (global)Full-timeView role+
Design the dashboards, alert surfaces, and webhook configuration UIs that traders and desks actually trust at 3am. Information density done with restraint.
- Design alert cards, cluster timelines, watchlist flows, and the backtest console
- Run weekly user sessions with active traders and desk operators
- Maintain the SpotX design system in Figma + Storybook parity
- Prototype motion and microinteractions in code with the frontend team
- Information-dense UI (Bloomberg, Linear, Vercel, Stripe Dashboard reference points)
- Familiarity with on-chain primitives (wallets, txs, slippage, MEV)
- Comfort prototyping in HTML/CSS/Tailwind — not just Figma
- Critical thinking about chart-junk vs. signal
4–7 years; prior fintech, terminals, or developer-tools experience strongly preferred
Use v0 / Lovable / Cursor for first-pass component scaffolding. Comfortable pair-designing with Claude or GPT-5 to explore divergent layout options.
The people who ship the pipe.
Real-time data, ML, infra. We ship to production weekly behind feature flags and own our SLOs.
Senior Frontend EngineerSenior · IC Remote (EU / US-East)Full-timeView role+
Build the production trader-facing surfaces — dashboards, the live alert stream, and the public marketing site — with a strong taste for motion and performance.
- Own the React + Vite app and the marketing site code-base
- Push p75 LCP under 2.0s on every public page
- Build live data UIs against WebSocket feeds with thoughtful reconnection / backpressure
- Set the testing & component-library bar with the Product Designer

- Tailwind, semantic-token design systems, framer-motion
- Streaming data UIs — WebSocket, SSE, gRPC-web
- Performance instrumentation (Web Vitals, React Profiler, Lighthouse CI)
5+ years, with at least one product where animation quality was a differentiator
Default to AI-assisted coding (Cursor, Claude Code, Lovable) for boilerplate and refactors. Expected to review AI output critically — own the diff like you wrote it yourself.
Senior Backend Engineer (Real-Time)Senior · IC Remote (global, ±5h US-East)Full-timeView role+
Build the ingestion → detection → delivery pipeline that keeps measured alert latency low across four chains.
- Operate the multi-vendor RPC mesh with active failover (Helius, Alchemy, QuickNode, Hyperliquid API)
- Tune the cluster-detection workers and the webhook fan-out service
- Own SLOs for end-to-end latency, alert-loss rate, and webhook delivery success
- Lead post-mortems and run game-days against ingestion failover
- Stream processing (Kafka / Redpanda, Flink, or hand-rolled in Rust/Go)
- Postgres at scale, time-series patterns (TimescaleDB or partitioned Postgres)
- Networking depth: HTTP/2, WebSocket, gRPC, TLS, retries with jitter
- Production debugging mindset — not afraid of perf flame graphs
6+ years, ideally one role operating a low-latency or trading-adjacent system
Comfortable using LLMs to draft SQL, write tests, and explain unfamiliar code, while staying skeptical of hallucinated APIs — ground truth always wins.
ML / Signal Research EngineerSenior · IC Remote (global)Full-timeView role+
Improve the signal-engine model: smart-money entity resolution, cluster scoring, and forward-return calibration. Half engineer, half quant researcher.
- Maintain and extend the entity-resolution model across new chains
- Run weekly precision/recall reviews on shipped signals against forward returns
- Design and deploy new factors; A/B test scoring changes against the live cohort
- Publish methodology updates to the public Methodology page
- Classical ML feature engineering (gradient boosting, calibration, drift detection)
- Statistical rigor — base rates, look-ahead bias, multiple-testing correction
- Comfort working with on-chain data (mempool, traces, DEX router decoding)
- Clear written communication of model trade-offs
4–7 years; equally weighted between ML and crypto-data fluency
Use LLMs to accelerate ad-hoc data exploration and to draft labeling heuristics. Production model lifecycle stays deterministic and reproducible.
DevOps / SREMid–Senior · IC Remote (EU preferred for on-call coverage)Full-timeView role+
Keep the platform up at the 99.95% SLA we promise our Desk-tier customers. Own observability, incidents, and the cost curve.

- Define SLOs, error budgets, and the on-call rotation
- Drive cost optimisation across compute, RPC providers, and egress

5+ years, with at least one 24/7 on-call cycle under your belt
Expected to use AI for incident summarisation, runbook generation, and Terraform scaffolding. Never let AI ship infra changes without a reviewed plan.
Where trust gets earned.
Automation-first, but with a human in the loop on every signal we ship. The alert tape is sacred.
QA Engineer (Automation-First)Mid · IC Remote (global)Full-timeView role+

- Data validation for streaming systems
- Diplomatic bug-reporting that engineers actually act on
3–5 years; bonus for experience with streaming or financial-data systems
Use LLMs to generate test scaffolding from PRs and to triage stack traces, while validating coverage manually — AI-generated tests must still test the right thing.
Signal QA AnalystMid · IC Remote (US or EU hours)Full-timeView role+
