You will be fully responsible for the full concept-to-performance loop, generating the angles, driving production volume, running structured tests, performing competitor research, and turning creative-level data into the next round of winning concepts. This is a high-impact role. Your ad creatives will be the primary performance lever: your work moves CTR, CVR, CPA, and ROAS directly, and you are accountable for those numbers alongside the User Acquisition team. The bar is high and so is the upside; performance here is directly and significantly rewarded. KEY RESPONSIBILITIES - Creative Strategy & Concepting - Own the creative angle strategy: Define which hooks, pains, and value propositions get tested next - Develop creative concepts: demo-led ads, UGC-style video, statics, and AI-generated formats - Translate product features and capabilities into concrete, scroll-stopping propositions for target audiences - Build and maintain a documented library of proven angles, hooks, and creative patterns PRODUCTION & TESTING VELOCITY - Own the creative pipeline across ad networks (Google, YouTube, Meta, Snapchat, TikTok, Applovin, etc) shipping new concepts every week - Structure systematic A/B testing frameworks, isolate variables, and analyze the results to bring solid conclusions. - Produce clear creative briefs for designers to execute high-performing concepts aligned with the brand. PERFORMANCE ANALYSIS & ITERATION - Own creative-level metrics: hook rate, hold rate, CTR, CVR, CPA, and ROAS - Generate testable hypotheses from performance data and retire underperforming angles quickly - Identify winning patterns, codify why they work, and scale them into new concept batches - Deliver structured creative performance reviews with clear recommendations for the next cycle MARKET RESEARCH & COLLABORATION - Run systematic competitor creative research across ad libraries and creative intelligence tools - Track emerging formats, platform policy shifts, and creative trends in the consumer AI category - Communicate daily with User Acquisition Managers, taking briefs on which angles need more volume QUALIFICATIONS Must-Have Experience - 4+ years producing performance ad creative for D2C or subscription consumer products - Proven track record of high-volume output, shipping and live-testing multiple new concepts weekly - Deep working knowledge of the major ad network ecosystems (Google, Meta, TikTok, Snapchat, etc). - Demonstrated fluency with an AI production stack across image, video, voice, and scripting tools - Ability to read creative-level performance data independently and act on it without an analyst in the loop - Experience building structured creative testing frameworks, not ad-hoc one-off tests - Strong portfolio of ads with verifiable performance results. (Applications must include a CV and a portfolio of ad creative you personally produced). Leadership Attributes - Systematic operator. You build repeatable creative processes, not one-time wins - Fully accountable for performance outcomes, not just delivery of assets - Fast and decisive under volume. Comfortable killing your own concepts when data says so - Treats User Acquisition as a working partner, not a downstream recipient of files LOCATION Ruby Labs operates within the CET (Central European Time) zone.

Location: Remote - International Workplace: Remote About Somnia: SOMNIA is the Agentic Chain - a hyper-performance L1 operating at an order of magnitude faster than existing networks. We empower builders and traders to create real-time, autonomous, and fully decentralized products, powered by agents, that were previously impossible and cannot be built anywhere else. It’s where the future of Web3 protocols will be built, so we’re facilitating a new wave of on-chain applications from DEX to Prediction Protocols and much, much more. Somnia is being developed by Somnia Foundation backed by Improbable https://www.improbable.io/, a British tech Unicorn +++ that has been at the forefront of building virtual worlds for over a decade. Somnia received initial funding from MSquared https://www.msquared.io/, which raised $150 million https://www.businesswire.com/news/home/20220407005101/en/Improbable-Raises-US150m-to-Establish-M%C2%B2-MSquared-a-Metaverse-Network-and-Ecosystem-Powered-by-Its-Morpheus-Technology from a16z crypto, SoftBank, Mirana Ventures, CMT Digital, and SIG. About the Role: DreamDEX makes a hard claim: CEX execution without DEX custody. A fully on-chain CLOB with sub-10ms, zero trading fees, self-custody and transparent rules, competing head-on with Hyperliquid, Lighter and the large centralised exchanges. An exchange wins or dies on liquidity, and early liquidity comes from relationships. Market makers must sign and quote tight. Builders must route flow to us. Institutions must trust a new venue with size. You will own those relationships. You'll run business development for dreamDEX and carry the wider Somnia story (the L1, Somnia Agents, Prophecy) into institutional conversations. You'll work directly with the GTM leads and core team, with a mandate to source, structure and close the deals that put depth on the book and volume through it. We measure every deal by the liquidity, volume and TVL it produces. Key Responsibilities: - Own the market maker pipeline: source, pitch, negotiate and onboard MMs, from DeFi-native firms early on to an anchor tier 1 relationship, structuring deals across CLOB rewards, fee arrangements and liquidity commitments - Get DreamDEX integrated with the major spot and cross-chain aggregators, then manage those relationships so we keep winning flow on price - Build and activate the institutional pipeline: trading firms, funds, family offices, OTC desks, prime brokers and custodians, with white-glove onboarding for qualified institutions - Build an active Builder pipeline: Trading terminals, AI strategies and native apps to drive users and volume to the Dex. - Close liquidity deals that grow TVL: institutional LPs, protocol and DAO treasuries, and vault operators - Land distribution partnerships that feed the exchange: wallets, perp aggregators and bridges - Support broader Somnia BD where your network applies: ecosystem projects, stablecoin partners and treasury deals on the L1 - Feed market intelligence back to product: you hear first what MMs and institutions need (RFQ flow, reporting, credit arrangements, API features) and help shape the roadmap - Represent DreamDEX and Somnia at conferences and in the rooms where these deals get done Requirements: Must Have - Business development experience at a crypto exchange (CEX, perp DEX or spot DEX) covering market makers, institutional clients or listings - A real network across institutions in crypto and/or TradFi: trading firms, market makers, funds, prime brokers and OTC desks. You open doors on day one rather than building a list from scratch - Closed deals with measurable impact on volume, liquidity or TVL, and the ability to walk us through the numbers - A working understanding of exchange mechanics: order books, spreads and depth, perps and margin, liquidations, MM economics and incentive design - Ability to run a full deal cycle alone, from sourcing through structuring and negotiation to post-signature relationship management - Comfort operating early in a venue's life, when you are selling the roadmap as much as the product Nice to Have - TradFi background in prime brokerage, electronic trading or institutional sales - Existing relationships with DEX aggregators, wallets, custodians or vault operators - Experience taking a new venue through cold start; you have solved the empty order book problem before - Experience structuring token or incentive-based deals - Working knowledge of DeFi: CLOB DEXs, vaults, stablecoins and yield products - Experience selling to DAOs and protocol treasuries Why Join Somnia? Design The Future: Join Somnia to work remotely with a global team, earn competitive compensation with token incentives, and help build the future of Web3 at a company where your impact truly matters. First of its Kind: Make Somnia famous as the only hyperspeed L1 with native AI inference. High Stakes: Influence a brand targeting a $1M+ launch budget in the 2026 peak-fragility market. Incentives: Competitive salary + tokens. Role Location The role is remote, but we are looking for someone based on a UK-friendly timezone (+/- 4 hours).

This team builds and operates the backend services that power blockchain account management, transaction processing and on-chain data aggregation across all Ledger wallet surfaces, from Ledger Live to Ledger Enterprise, the custody platform used by financial institutions.

We take time to share, challenge, and grow together through bi-weekly knowledge-sharing sessions, meetups, conferences, and open source contributions.   What you’ll be doing - Design, build and operate the Scala services that connect Ledger wallets and the Ledger Enterprise platform to blockchain backends: account creation, operation history, transaction crafting, broadcast and lifecycle tracking. - Lead new blockchain integrations end to end, from the integration design (ADR) to production, across account-based, UTXO and privacy-preserving chains. - Own production quality on your scope: SLIs and SLOs, observability, distributed tracing. Take part in the firefighting rotation and drive incidents to resolution, including those raised by institutional clients. - Define clear contracts with the Coin Integration and Ledger Enterprise teams, for example where UTXO selection lives or how transaction states are exposed to consumers. - Write and review ADRs, challenge designs, and raise the bar on code quality, testing (including end-to-end on testnets) and technical debt management. - Work in an AI-native way: use coding agents daily, write the specifications, constraints and verification that let them deliver safely, and contribute to the team's AI tooling. - Mentor other engineers and share your knowledge across the Backend Blockchain community.   You will collaborate cross-functionally with: - The Coin Integration team for coin modules and new blockchain integrations. - The Ledger Enterprise team, main consumer of the team's services for institutional custody. - The Ledger Wallet, Ledger Button and Wallet XP teams as consumers of the team's backend APIs. - The Blockchain platform team for data model alignment, indexing and event streaming. - The Infrastructure and SRE teams for deployment, reliability and scalability. - The Security team (Donjon) for vulnerability analysis and remediation. - The Product team for roadmap prioritization and customer-driven requirements.   What we’re looking for - 5+ years of backend engineering, with real production ownership of distributed systems. - Strong production experience - Interest for Scala and functional programming practice - Hands-on blockchain integration experience: transaction lifecycle, fees, finality, reorgs, on at least two models among account-based, UTXO and privacy-preserving chains. - Experience with event-driven systems and data infrastructure (PostgreSQL, RabbitMQ, NATS or equivalent) and with observability tooling (Datadog or equivalent). - Able to diagnose an incident across several services and own the outcome, from root cause to fix in production. - Comfortable reading and contributing to TypeScript code, as the team works on a polyglot stack. - Daily use of AI coding tools, with a critical eye on their output. - Clear written communication in English, especially for design documents and incident reports. At Ledger, we are dedicated to continually investing in our employees which is why we offer more than just salaries; we provide comprehensive compensation packages that include a wide range of benefits. Here are some of the benefits you can look forward to: - Flexible work options - Our hybrid policy allows employees to work from home up to 3 times per week - Health & Wellness support - Health and Life Insurance. - Financial growth opportunities - Employees can become shareholders in Ledger as well as other financial benefits depending on your country of work. - Commuter allowance - Ledger offers a commuter allowance to contribute to your preferred means of transportation. - Learning & Development - A comprehensive suite of training solutions providing a personalised learning experience for every employee. For regionally specific benefits, your Talent Acquisition contact will be able to provide you with more information. We’re committed to building an inclusive hiring process. If you need any adjustments or accommodations, just let us know, we’ll do our best to support you.
