Job Details

Shape the Future of Computing We're building technology that automatically parallelizes Java applications by transforming bytecode post-compilation. Our proof of concept already shows a 2.8x speedup on real workloads without requiring source code changes. Now, we're looking for a brilliant JVM engineer to help turn this into a game-changing product.For a deep dive into our current approach and early results, check out our recent technical blog post showing 2.8x speedup through automatic bytecode parallelization or here (for a really deep dive).The Role You'll work directly with our founding team to evolve our automatic parallelization engine from proof-of-concept to production-ready system. You'll dive deep into bytecode manipulation, control flow analysis, and concurrent execution patterns while helping shape our product strategy.The Challenge Transform our working prototype into a robust, production-grade systemExtend parallelization capabilities to handle complex scenarios (branching, object references, exceptions)Design and implement sophisticated program analysis techniquesBuild tooling to make parallel execution safe and efficient across diverse codebasesHelp shape our product roadmap based on real-world use casesWhat You Bring Must Have Comfort with startup "lifestyle" (high expectation, high pressure, uncertainty, instability but a career defining opportunity if it works out)Deep understanding of JVM internals and bytecode manipulationStrong grasp of Java concurrency and thread safety principlesExperience with control flow analysis and program transformationSolid background in parallel computing conceptsExcellent problem-solving skills and attention to detailStrong written communication skills for remote collaborationComfort with ambiguity and rapid iterationNice to Have Experience with BCEL or similar bytecode manipulation librariesBackground in building developer tools or performance optimization systemsFamiliarity with static analysis techniquesExperience turning prototypes into production systemsPrevious remote work experienceStartup experienceWhy Join Us The Opportunity Work on cutting-edge technology that could revolutionize software performanceShape the direction of a foundational product from its early stagesJoin as an early engineer with significant equity upsideLearn and grow rapidly in a fast-paced environmentWork remotely with a focused, talented teamBenefits (US-based) Comprehensive health insurance401(k) planFSA availabilityRemote work setupRegular team on-site for collaborationOur Work Style Fully remote with quarterly in-person team meetingsHigh autonomy and ownershipDirect communication and rapid feedbackFocus on impact over processLearn and adapt quicklyAbout Us We're InboxBooster, an early-stage startup that began by solving critical email deliverability problems - helping companies stay out of spam folders. While building our email platform, we discovered an opportunity to dramatically improve software performance through automatic parallelization.This new direction emerged from our hands-on experience with high-performance systems. Our proof of concept already shows dramatic speedups on real workloads, and we're now building out a dedicated team to turn this into a transformative product.We believe computation is a cornerstone of modern society, and making it more efficient can have a massive impact. We're looking for engineers who are excited by both the technical challenge and the opportunity to shape a new direction.Next Steps If you're excited about pushing the boundaries of software performance and want to join an early-stage startup with massive potential impact, we'd love to talk.
