Only ReversingLabs delivers the software package analysis speed and depth needed to protect against software supply chain risk.\nOur vision is clear: to arm every company with end-to-end insights so that development teams release securely, IT purchases safely, and the SOC can effectively detect, isolate, and respond. We are seeking extraordinary talent for this game-changing opportunity to help forge this transformational journey at ReversingLabs.\nSoftware risk hides in many places - in the open-source packages developers pull in, in the commercial and third-party software that enterprises buy and must vet before trusting it, and in the releases software publishers ship to their own customers.\nPart of what our team quietly maintains is a curated body of knowledge about the software the world runs on - what it is, where it comes from, how it behaves, and what makes it risky. Keeping it accurate, well-structured, and growing is as much an engineering and data challenge as a security one.\nAs a Senior Software Engineer, you’ll design and build the scripts, tools, and automation that make our processes fast, repeatable, and reliable. You’ll lean on solid engineering instincts, a pragmatic sense of what’s actually worth automating, and modern AI tooling to move quickly.\nYou don’t need to be a security expert on day one. But you should be genuinely curious about the domain - because the people who thrive long-term at ReversingLabs are the ones who learn how attacks work, what makes software risky, and how detection gets built. The deeper your understanding of the domain, the more impactful the problems you’ll get to own.\nWhat you’ll do\nDesign, build, and maintain the tools and procedures that power threat hunting, analysis, and detection at scale, using AI where it helps\nBuild and own the frameworks that safeguard the data quality of our curated databases - the automated checks and guardrails that keep that data accurate, trustworthy, and up to date\nWork side by side with domain experts - understand their day-to-day workflows, then suggest and build tooling that makes their work faster and more efficient\nWrite solution design documents - frame the problem, weigh the options, and set out an approach you and the team can build on\nWhat we’re looking for\nStrong software engineering background - you write clean, maintainable code and think about structure and systems, not just output\nOwnership and initiative - you take full responsibility for your work, hold it to a high standard, and drive things forward\nKeen interest in current security trends, across open-source and commercial software alike\nProficiency in Python (or another object-oriented language), paired with hands-on experience using AI coding tools (e.g., Claude Code, Codex) to automate your own workflow\nComfort working with data - spotting patterns in large datasets and analyzing them in Python or SQL\nExcellent spoken and written English\nNice to have\nSoftware architecture experience - designing systems, not just features\nApplication security knowledge, or a solid sense of how software is built, packaged, shipped, and attacked\nFamiliarity with industry standards and terminology such as SBOMs, CVE, CWE, and CPE\nInterest or experience in reverse engineering - debuggers, disassemblers, static/dynamic analysis (bonus points if you took the Reverse Engineering course at FER)\nBenefits\nHybrid work options (paid accommodation & transportation to Zagreb during onboarding for remote employees)\nFlexible working hours\nGenerous compensation and a bonus system based on annual performance\nHefty personal education budget and possibility to attend leading conferences and seminars in the field\nCompany library and possibility to order books of choice via Amazon\nPermanent contract in a fast-growing global company with Fortune 500 & governmental agencies as clients\nChallenging projects in a dynamic, collaborative team\nGreat career advancement opportunities - clear goals & internal promotions\nEmployee referral bonus program: EUR 1,060 net for junior position, EUR 2,123 net for mid to senior positions, and EUR 2,654 net for principal/managerial positions\nMultisport card, annual health checkup, newborn child allowance, rent-cost, and 3rd pillar pension benefits\nWellness Weekends - quarterly, company-wide three day weekend, starting with a company paid Friday off for all employees\nFully covered car garage in Radnička for all employees\nAbout ReversingLabs\nReversingLabs is the leader in software supply chain security, helping the world's most security-conscious organizations detect and respond to threats hidden inside software. Our platform is trusted by Fortune 500 companies, government agencies, and security teams globally. We're a company that takes the work seriously and takes care of the people doing it.\nCareers Page · LinkedIn · Our Technology","description_format":"text","description_chars":5113,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Flexible schedule","Hybrid work"],"hiring_locations":[{"name":"Croatia","iso":"HR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity","Threat Intelligence","DevSecOps"],"lifecycle":[{"event":"open","at":"2026-10-27T16:34:11Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":18,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/reversinglabs-senior-software-engineer-2","json_url":"https://alion.io/job/reversinglabs-senior-software-engineer-2.json","meta":{"generated_at":"2026-11-02T00:42:52Z","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":1188,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":17650},"rest":"https://alion.io/mcp/rest/get_company?id=17650"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Freversinglabs-senior-software-engineer-2"},{"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%2Freversinglabs-senior-software-engineer-2"},{"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%2Freversinglabs-senior-software-engineer-2"},{"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/reversinglabs-senior-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Freversinglabs-senior-software-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3343796}},{"tool":"search_jobs","arguments":{"company":"reversinglabs.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3343796},"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); https://alion.io/mcp with an Alion account has everything.
