Product Software Engineering

PlantingSpace

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics. We are looking for Product Software Engineers with experience in the commercialization of research software. You will contribute to the productization of our system, by developing use-case demos that clearly demonstrate its strengths and unique value. Tasks will focus on implementing applications from quantitative domains (financial analysis, physics simulation) within the framework of our system, identifying the unique strengths of our system and developing showcase demos. You will also contribute to, identifying limitations, closing gaps and helping improve the product based on these insights. USEFUL EXPERIENCE * Experience in turning research software into product * Applied mathematical modeling in finance and/or scientific applications * Experience in a collaborative, commercial software engineering environment, working on large codebases and using practices like CI/CD, testing, and code reviews * Strong foundation in computer science algorithms and data structures * Julia, or usage of some more functional or typed languages, e.g. Rust, OCaml, Clojure, C++, or Haskell * Profiling and performance optimisation * Mathematics, Computer Science, or Statistics advanced degree RESPONSIBILITIES * Work with product team to define new features * Define implementation strategies, and work with others to implement them * Deliver defined features with a user oriented mindset * Leverage the expertise of other team members effectively * Write design documents for more complex problems * Write clean and performant code * Help other team members to deliver on their goals REQUIRED MINDSET We've found that our successful team members share some key characteristics, and as we've grown our team, these are the qualities we've learned to seek out. We take pride in our strong, collaborative culture, and these core attributes not only reflect our shared values, but can help you evaluate how well you might fit into our team: * A builder at heart: You’re passionate about building things, solving complex problems, and approaching challenges with an entrepreneurial spirit and humility. Your sharp sense of prioritisation gives you a laser focus on delivering results that uplift the entire team, moving us closer to our goal. * Results-driven: You thrive when taking full ownership of tasks, seeing them through from start to finish, and taking accountability for the results. You’re proactive, resourceful, and avoid over-complication - anticipating problems, even in complex, uncertain environments. * Growth mindset: You are intellectually curious, have a critical mind, and seek opportunities to stretch your abilities. You explore the state-of-the-art, you dig deep to truly understand a problem, and question assumptions. * A strong collaborator: You naturally communicate with clarity and purpose, ensuring your ideas and updates are easily understood. You work efficiently, embracing an iterative approach that allows for frequent progress and course correction. You’re open to direct feedback, adapting quickly and using it to improve both your work, and the performance of those around you. * Approaching problems and tasks like a project manager: * You can take a given goal and break it down into smaller parts. * You can solve problems systematically, by yourself as well as collaboratively with others. * You involve others in effective problem-solving sessions because you value getting to the best solution over being right. * You document processes well to ensure others can jump in to collaborate effectively.

Twin Labs

FOUNDING PRODUCT ENGINEER BUILD THE FUTURE OF AUTONOMOUS COMPANIES At Twin, we're building a world where anyone can deploy AI agents capable of running real business operations. Not chatbots. Not copilots. Autonomous agents that take actions, make decisions, execute workflows, and create value. In just a few months, we've seen explosive adoption, thousands of users building businesses on top of Twin, and millions of agent actions executed. We're still at the beginning. We're looking for a Founding Product Engineer to help build the company that builds companies. THE ROLE This is not a traditional software engineering role. You won't receive tickets from a product manager. You won't spend months discussing roadmaps. You won't optimize a tiny corner of an existing system. You'll work directly with founders, users, and other builders to design, build, and ship product every day. You'll move across product, engineering, design, AI, infrastructure, and growth whenever needed. One day you might: * Build a new agent capability from scratch * Design an onboarding flow that doubles activation * Improve infrastructure supporting millions of executions * Talk directly with power users * Ship a feature in the morning and iterate on feedback the same afternoon * Use AI to prototype something in hours that would previously have taken weeks If that sounds exciting, keep reading. WHO WE'RE LOOKING FOR We're looking for builders. People who create. People who ship. People who don't wait for permission. You might be a fit if: * You've built products people actually use * You've launched startups, side projects, open-source projects, or meaningful products * You think about users as much as technology * You enjoy turning ideas into reality extremely quickly * You thrive in ambiguity * You naturally take ownership * You care about product quality * You love learning AI-NATIVE ENGINEERING We believe the best engineers of the next decade will not be those who type the fastest. They will be those who can effectively direct, evaluate, and collaborate with AI. AI coding assistants should already be part of your daily workflow. Cursor. Claude Code. Codex. Or whatever tools help you move faster. You should be comfortable: * Pair-programming with AI * Generating and reviewing large amounts of AI-generated code * Using AI for debugging, prototyping, testing, and research * Building dramatically faster without compromising quality * Leveraging AI as a force multiplier The question is no longer: "Can you write the code?" The question is: "Can you use AI to build the right thing, verify it, and ship it?" STRONG SIGNALS These are not requirements, but they tend to correlate with success here: * Former founder * Early-stage startup experience * Open-source contributor * Exceptional side projects * Competitive programming background * Olympiad participant * Hacker mindset * Product obsession * Evidence of unusually fast learning WHAT WE VALUE OWNERSHIP You see a problem, you solve it. SPEED Fast iteration beats endless planning. JUDGMENT Good decisions scale better than good code. AMBITION We're building something that shouldn't be possible. CRAFT Fast doesn't mean sloppy. WHY TWIN? Most companies hire engineers to execute a roadmap. At Twin, you'll help define it. Most engineers optimize existing systems. At Twin, you'll help invent new ones. Most jobs offer impact on a feature. This one offers impact on the future of the company. IF YOU'VE EVER THOUGHT: "I wish I had joined earlier." This is one of those moments.
