Our web2web, credit-based monetization model runs on different funnels, different logic, and different insights than the mobile-subscription products most competitors build, and your work will plug directly into a UA team already managing $300K+ per month with a clear path to $1M+, so every hypothesis gets tested against real volume, fast. You'll make decisions without red tape, own the creative direction end-to-end, and build a team of 6 creative marketers and designers over the next 3–6 months in a place where 70% of our heads and leads have grown from within

So, you will be part of an ambitious journey toward our clear goal: becoming one of the Top-5 international social networking platforms globally. We are already succeeding in our current markets, and now we are ready to bring that same thoughtful approach to worldwide scale.

In this role, you will

• Own the end-to-end creative strategy across paid channels, starting with Meta and expanding into Snapchat, TikTok, and Google, in close partnership with the UA team
• Run the full creative cycle: research, insight, hypothesis, brief, production, launch, analysis, and iteration
• Generate original creative concepts, narratives, angles, and messaging tailored to different audience segments, not just hooks
• Build and evolve a creative testing methodology, from hypothesis design to clean test execution and pattern recognition
• Hire, lead, and grow a team of 6 creative marketers and designers, setting quality standards and giving hands-on feedback
• Track competitors and trends through Meta Ad Library, TikTok Creative Center, and Google Ads Transparency Center, turning observations into prioritized creative bets
• Embed AI tools into the creative production pipeline to increase testing speed and volume

It's all about you

• 3+ years in creative marketing, performance creative, or creative strategy, including 1+ year leading or mentoring a creative team
• Strong performance background and a direct-response mindset – you know why a creative works, not just that it does
• Hands-on experience scaling creatives for Meta as a primary channel, plus practical experience with Snapchat or TikTok Ads
• Fluency in creative metrics (hook rate, hold rate, thumbstop rate, creative win rate, CTR, CPA, ROAS) as everyday decision-making tools, and a clear view of how creative connects to registration, first purchase, revenue, and LTV
• A track record of concepts you personally scaled, backed by real numbers
• Daily, practical use of AI tools for creative generation and research (Midjourney, Runway, Kling, Pika, HeyGen, Krea, or similar), with your own workflows or prompts you can walk us through

Backend Trading Systems Engineer

BlockRouteLabs · Remote · Contract

About BlockRouteLabs

At BlockRouteLabs, we build systematic trading infrastructure and strategies for digital asset markets. Our focus spans centralized exchanges, decentralized finance (DeFi), and on-chain execution environments. We prioritize transparency, statistical rigor, and real-world performance.

Founded in 2020 and operating as a globally distributed team since 2026, we are a lean team of 11–50 specialists. We trade proprietary capital — internally funded and grown through reinvested trading profits — which keeps us independent, fast-moving, and focused on real results.

About the Role

As a Backend Trading Systems Engineer, you will build and operate the production systems that run our strategies live: market-data ingestion, order routing and execution, position tracking, and real-time risk controls across centralized exchanges and DEXs.

This is money-moving code in a market that never closes — correctness, reliability, and observability come first. You will work closely with the quant and simulation teams to take strategies from research into dependable production systems.

Responsibilities

• Design and build backend services for real-time market-data ingestion, order management, and execution
• Implement and maintain venue integrations, including CEX REST/WebSocket APIs and DEX smart-contract interaction
• Build order-lifecycle management, position tracking, and reconciliation against venue records
• Implement pre-trade and runtime risk controls, including exposure limits, rate limiting, and kill switches
• Engineer for reliability: failover, idempotent order handling, graceful degradation, and safe restarts
• Instrument systems end to end with metrics, structured logging, alerting, and dashboards
• Partner with quant and simulation teams to deploy strategies from research into production
• Contribute to testing standards, code review, incident response, and postmortems

Qualifications

• 4+ years of backend engineering experience building distributed, real-time, or high-throughput systems
• Expert proficiency in at least one of Python, Go, Rust, or C++ [narrow this to your actual stack]
• Hands-on experience with WebSocket/REST API integrations, messaging or streaming systems (e.g., Redis, Kafka, ZeroMQ), and relational or time-series databases
• Strong fundamentals in concurrency, networking, and performance
• Rigor around correctness in systems that handle money: testing, reconciliation, and defensive design
• Ability to communicate clearly and document systems well

Preferred Qualifications

• Direct experience with crypto venues: exchange API integrations (e.g., via CCXT or native clients) or DEX interaction through web3 tooling
• Understanding of on-chain transaction mechanics, including nonce management, gas strategy, and MEV-aware submission (e.g., private relays)
• Prior work on OMS/EMS, market-making, or other latency-sensitive trading systems
• Ability to read Solidity and reason about smart-contract behavior
• Experience operating 24/7 production systems with on-call responsibility

What We Offer

• Ownership of production systems where correctness and uptime directly protect trading capital
• Access to production-grade market data, execution infrastructure, and real trading feedback loops
• A small, senior team with minimal process overhead and fast decision-making
• Compensation tied directly to the quality and impact of your work

Position Details

• Type: Contract (independent contractor), fully remote
• Commitment: Part-time (20 hours per week) or full-time (40 hours per week)
• Term: Initial [3–6 month] engagement, with the option to extend or convert to a longer-term arrangement based on results and mutual fit
• Hours: Flexible, with at least [4] hours of daily overlap with US Eastern Time (ET)

Compensation

• Contract rate of $70–90 per hour (USD), benchmarked against top-tier quant and crypto firms
• Performance-based bonus tied to your impact and overall trading performance
• Equity or token-based incentives, where applicable

Hiring Process

1. Intro call (30 minutes) — background, motivation, and mutual fit
2. Technical discussion (60–90 minutes) — system design, concurrency, and venue/API integration
3. [Paid] coding exercise — a scoped task, such as building a small, well-tested order-handling or market-data service
4. Final conversation — logistics, expectations, and offer

We aim to complete the full process within [two to three weeks].
