Our Technology team is small and therefore you get a lot of responsibilities and freedom! You are triggered by being faster than the competitors and you like to focus on quality. As you can imagine in a small team, there is a flat hierarchy and everybody is really hands-on to be the best in what we do!\nWe are looking for senior C/C++ Engineers with extensive knowledge and experience in building, testing, monitoring and maintaining large scale parallel applications and databases. As a C/C++ Engineer at Mathrix in the low latency environment, your focus will be on the code which facilitates the automated trades on various exchanges worldwide.\nOur companies’ performance is highly dependent on the performance of our data processing pipelines. You will regularly need to appeal to all aspects of your developers’ skillset to find new and innovative ways to optimize your code. Some examples:\nlow-latency networking code for fast communication with exchanges\n\ncontext-switch-free code\n\ndesign and implement custom data storage structures with minimalistic footprint\n\ndata pipelines using a streaming paradigm\n\ncomplex trading logic for the decision engine with the lowest possible compute time\n\nre-implement existing code using advanced features of the CPU (SIMD)\n\nTo accommodate the growth of the company, we spend increasing efforts on the maintainability and manageability of our large, highly optimized and multithreaded codebases while preserving its main purpose (low latency). You will have to maneuver yourself between these worlds to get the best results.\nIn addition to writing code, the Technology team builds and maintains the global (hardware) infrastructure to facilitate the trading. In your job you will be regularly involved in all aspects of the pipeline and different tech stacks; from hardware compositions, network design to data logging pipelines for the traders and quants.\nRequirements\nWho are you\nDue to the growth of our organization, we are looking for more than one C/C++ Engineer. As the new team member, you bring the following skillset:\nextensive and thorough knowledge of C and C++ in Linux\n\nan understanding of - and the ability to verify - the assembly the compiler will produce from the code you write\n\nunderstanding what (GNU/Linux) system calls you invoke will do and cost\n\nknowledge of x64 hardware and how to use it efficiently\n\nunderstanding what storage structures to select or implement given their use (time complexity)\n\nability to work with debuggers and profilers\n\noperative coding (git, documentation)\n\nability to absorb from and provide knowledge to the team\n\npro-active, a self-starter, honest, flexible and stress resistant\n\nIn addition to the above, having a background in one of the specializations below are nice to have:\nexperience with network engineering; either (low latency) networking hardware deployment or networking protocol implementations\n\nexperience with Big Data engineering and knowledge of Big Data best practices and implementations best suited for different use cases\n\nWhat we offer\nExcellent remuneration (including discretionary bonus)\n\nFun and inspiring work environment\n\nExperienced and knowledgeable colleagues\n\n25 vacation days\n\nAdditional benefits: going out for dinner regularly, Friday afternoon drinks, yearly office trip(s), weekly massages, monthly meal allowance","description_format":"text","description_chars":3400,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-11T13:14:24Z"},{"event":"open","at":"2026-09-26T08:48:42Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.211,"p_room":0.28,"age_days":661,"expected_fill_days":28,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/mathrix-senior-cc-low-latency-engineer","json_url":"https://alion.io/job/mathrix-senior-cc-low-latency-engineer.json","meta":{"generated_at":"2026-10-31T12:51:51Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":19908,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":679248},"rest":"https://alion.io/mcp/rest/get_company?id=679248"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmathrix-senior-cc-low-latency-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmathrix-senior-cc-low-latency-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmathrix-senior-cc-low-latency-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/mathrix-senior-cc-low-latency-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmathrix-senior-cc-low-latency-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":743097}},{"tool":"search_jobs","arguments":{"company":"mathrix.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":743097},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
