From the very beginning, we have been driven by a deep commitment to applying cutting-edge scientific research and technological innovation to deliver unparalleled performance. Our journey is one of continuous growth and exploration, marked by a spirit of curiosity and relentless drive for excellence. \nAt Aquatic, we are actively recruiting for a Software Engineer to join our Core Data team. Core Data owns the data systems that our research and trading depend on, from real-time market data to alternative data and reference data, and we are expanding those systems as the firm enters new markets around the world. While all team members work across our entire platform, this position seeks to expand our expertise in “market-by-order” feed handling across global markets as a key skillset.\nYou will partner with colleagues across Research, Engineering, and Trading Operations. The team is lean, highly autonomous, and the work is hands-on and close to the business. Your efforts will have a visible impact across the entire firm.\nRole Details\nImplement and enhance market data feed handlers for proprietary equities protocols (ITCH, GTP, PITCH, and others), along with the data processes around them.\nBuild and maintain quant-ready data archives that researchers can trust for correctness, completeness, and consistency.\nCollaborate with quantitative researchers to understand how they use our data, and optimize the presentation of our data products accordingly.\nSupport the rollout of new markets as part of the firm's global expansion, identifying market nuances and recommending sensible solutions.\nShare expertise in market data processing tradeoffs with the broader team; identify opportunities for improvement and mentor growing teammates.\nParticipate in initiatives across the Core Data team, including reference data, universe, and non-market data.\nExemplify our engineering priorities: build systems you are happy to support, because they are clear, documented, and maintainable; leave systems you support a bit better for your touch.\nTechnical Experience\nBS/MS in Computer Science, Electrical Engineering, or a related technical field, or equivalent practical experience.\n5-10 years of professional software development experience, including 4+ years in the trading industry or hands-on experience at a market data provider.\nStrong C++ and Python, and a track record of building production-grade systems. Rust experience is a plus.\nHands-on experience implementing and maintaining handlers for proprietary equities protocols such as ITCH, GTP, or PITCH.\nStrong understanding of the information these feeds communicate: order book mechanics, trade and quote conditions, auctions, odd lots, corrections, and venue-specific behavior.\nExperience maintaining quant-ready data archives, including normalization, gap detection, reconciliation, and backfills.\nHelpful but not required: exposure to quantitative research needs, reference data, or modern data pipeline tooling (Dagster, Polars, or similar).\nCandidate Qualities\nStrong bias for action\nDriven by accountability and internal urgency\nDeep curiosity about data and the markets that produce it\nDesire to independently seek best solutions\nComfortable working across teams and building alignment with stakeholders who have their own priorities\nComfortable providing and receiving actionable feedback in a collaborative team setting\nMotivated by an ambitious environment and driven colleagues\nCompensation\nThe base salary for this role is anticipated to be between $150,000 and $300,000, which is based on information at the time of posting. This position may also be eligible for additional forms of compensation, such as a discretionary bonus, and benefits. Discretionary bonus can be a significant portion of total compensation. Actual compensation for successful candidates will be carefully determined based on a number of factors, including their unique skills, qualifications and relevant experience.\nBenefits:\nBenefits: For full-time employees, fully paid medical, dental, and vision for employees and dependents, competitive 401k plan, employer-paid life & disability insurance \nPerks: Wellness programs, casual dress, snacks, lunch, game room, team and company events\nDevelopment: Open environment to maximize learning and knowledge sharing\nTime: Generous PTO, paid holidays, competitive paid caregiver leaves\nAquatic Capital\nThis role represents a unique opportunity to join a quantitative investment manager in its early stage of growth. The firm’s culture will be shaped by collaboration, meritocracy, ambition, and calm determination.\nAquatic is a proud equal opportunity workplace.
