This is not a standard job posting; it is a curated search for a specific kind of engineer, and we are involved at every step of the process to make sure the fit is right on both sides. If you apply through Technacity, you will have a direct line to the hiring team, context on what Symbium is actually looking for beyond what any job description can capture, and a partner who will advocate for you throughout the process.Symbium is a San Francisco-based startup on a mission to reinvent how citizens interact with local government, starting with permitting for clean energy. Their platform — built on proprietary Computational Law (Complaw®) technology originally developed at Stanford's AI Lab — encodes government regulations as executable logic, enabling real-time permit compliance checks and instant approvals for solar panels, EV chargers, heat pumps, and more. They are live with 270+ cities across the US and growing fast. Every engineer at Symbium ships work that directly accelerates the country's transition to clean energy. This is not a company where your code disappears into a dashboard no one reads — it helps real people get real projects approved faster. The team is small (~9 people), tight-knit, and works side by side every day. C-level executives, engineers, and interns share the same space, debate the same decisions, and hold each other accountable to the same high standard. If you have wanted to work somewhere that moves fast, takes ownership seriously, and actually cares about what you're building, this is worth your attention.Symbium is hiring up to two Senior Software Engineers to support the next phase of platform growth. These two roles are intended to be complementary rather than identical:Lead the execution of Symbium's AI roadmap, ensuring determinism and accuracy in mission-critical workloads while building scalable, production-ready featuresBuild and maintain robust workflows, APIs, integrations, and backend systems supporting large-scale, high-reliability permitting functionsArchitect, design, and build platform components that can scale from 1 city to 1,000Drive engineering quality through strong practices in testing, observability, code quality, and data modelingTranslate regulatory text into logical statements and structured, verifiable code — bridging the gap between law and softwareOwn the schema underlying Complaw® workflows: add rule structures, extend reasoning capabilities, and keep the model accurate as laws evolveDebug rule chains by tracing logic from input facts to conclusions, preserving explainability at every stepTreat precision as a hard requirement — in mission-critical compliance workflows, wrong answers have real consequences for the people depending on themInfluence architectural decisions, tooling choices, and engineering standardsWork directly with the CTO and CEO to shape engineering priorities and technical strategyContribute to documentation, knowledge-sharing, and practices that strengthen team alignmentProvide thoughtful code reviews, design feedback, and peer mentorship (no people management)Onboard new engineers and help them understand systems, patterns, and architectural principlesWork cross-functionally with product, design, policy experts, and customers to clarify requirements and shape solutionsBeyond the technical requirements, it is the working style and mindset that succeeds at Symbium. The engineers who thrive here share a few things in common: They build from first principles. They do not reach for a framework before understanding the problem. They can reverse-engineer a system, reason about tradeoffs from the ground up, and explain their decisions clearly.They bring structure to chaos. When something is ambiguous, they do not wait for clarity to arrive — they create it. They know how to prioritize, ask the right questions, and come to the table with a point of view.They identify risks and push back constructively. Working directly with founders means being honest about what could go wrong. The best engineers here do not just execute — they flag concerns early, propose alternatives, and earn trust by being right more often than not.They know what they know and what they do not. Self-awareness is a core competency at a company this size. Engineers who can say \"here is what I know, here is what I need to find out, and here is how I will find it\" move faster and make better decisions than those who pretend to have all the answers.They have solved at-scale problems, more than once. Symbium is not looking for startup generalists — they are looking for engineers who have already operated at scale and know what that requires. The ideal background includes progression through multiple tiers of responsibility (associate, senior associate, senior engineer, and beyond) across companies of different sizes and stages. An engineer who spent several years at a large company being promoted through the ranks, then brought that experience into a smaller or faster-moving environment, is a stronger signal than someone with only early-stage exposure. What matters is that the at-scale problems are not new to you — you have solved them before and can apply that pattern recognition here.Required Qualifications:7+ years of hands-on software engineering experience, including designing, building, and maintaining production systems end-to-endDeep proficiency in JavaScript/TypeScript and Node.js, with experience building reliable systems on AWSStrong full-stack capabilities across backend services, APIs, cloud infrastructure, and modern front-end development (React)Extensive experience with databases, data modeling, and SQL — schema design, query optimization, and index strategy at scaleExperience developing AI/ML-driven features and integrating deterministic model-based systems into production workflowsDemonstrated engineering leadership: guiding architecture, influencing technical decisions, and mentoring engineersA collaborative working style with frequent check-ins and a bias toward early course correction over long stretches of solo workHigh ownership, accountability, and attention to detail in mission-critical environmentsPreferred Qualifications:Experience with logic, constraint, or declarative programming paradigms (Prolog, Datalog, or similar)Background in platform engineering, DevOps, or stack migration at scaleExperience building or integrating with government systems, regulated industries, or third-party APIs with strict compliance requirementsExperience building compilers, rule engines, or domain-specific languagesBackground that includes both large-company engineering (with progression through multiple seniority levels) and experience in a faster-moving or smaller-scale environmentDomain knowledge in permitting, clean energy, or government technologyMaster's degree or higher in Computer Science or a related fieldCompensation and Benefits:Base salary: $185,000 – $200,000Equity: Meaningful stock options in a growing, venture-backed companyBenefits: Competitive health coverage, 401k, and the kind of early-employee upside that comes with joining a company at this stageLocation: Onsite in San Francisco, CA — 5 days per week, near the Ferry Building.
