About Firstbase

Tens of thousands of businesses — from newly incorporated startups to public enterprises — rely on Firstbase to streamline compliance, finance, analytics, and every part of the back office. It is one platform to run your entire company.

Our goal is to make running a business feel like magic. We make it possible by owning the general ledger and unifying data across all business functions. Compliance tasks are flagged — and often resolved — automatically. Real-time business metrics are accurate, accessible, and easy to understand. And if you need to hire a new employee, send an invoice, or file taxes, you can do it from the same interface.

We're bundling what's never been bundled. We're not building an incorporation tool. We're not building an ERP. We're not building an "AI accountant." We are creating a new category entirely: the Company OS .

How We Work

We cherish the moments when noise fades and we move with clarity, confidence, and focus — doing the right thing at the right time. These moments are when our best work happens, and we strive to create more of them.

We value craftsmanship over busyness, clarity over complexity, and resilience above all — whether it takes hard work or patience. We aim high, avoid mediocrity, and speak with fearless transparency.

We believe in upward mobility and take pride in growing talent from within, always preferring to promote our own before looking externally.

About The Team

We're a small, nimble, and ambitious product team that thrives on collaboration, creativity, and impact. We value engineers who care deeply about clean code, strong architecture, and delivering an exceptional user experience to a global community of founders. From writing and reviewing code to shaping key product decisions, we're building software that's fast, scalable, and beautifully simple.

Our product is built using PHP, Golang, , Vue, MySQL, PostgreSQL, AWS. We also use Redis, Vue Router, Vuex, Docker Compose, Docker, GitLab CI, and Graylog, and some third-party API's like Stripe. We use Slack, Clubhouse, Notion, Whimsical, Figma, and G Suite to collaborate and build together.

What You Will Do

Step into one of the most pivotal engineering roles at Firstbase — where you'll scale a high-growth org, lead mission-critical architecture, and shape the future of our platform through world-class execution, innovation, and technical excellence.

Your Responsibilities Will Include

• Develop high-quality software design and architecture using Vue, PHP, and Golang
• Identify, prioritize, and execute tasks throughout the software development lifecycle
• Build tools and applications by writing clean, efficient, and maintainable code
• Write, test, and review code in a collaborative environment
• Collaborate with internal teams and vendors to improve our products
• Partner with product and design to define, shape, and plan deliverables
• Make sound technical decisions following best practices and engineering standards
• Identify and resolve issues that may affect product quality or business outcomes

You Should Meet The Following Requirements

• You Should Meet The Following Requirements

• Competitive salary & equity: We pay top-tier because you deserve it — plus generous equity package so you can share in the success of the future we're building together.
• Generous raises & stock refreshers: Your impact deserves recognition. We review compensation quite frequently to ensure you're rewarded as your role grows — including stock refreshers so you continue to share in the upside of what we're building together.
• Flexible work setup: We offer the freedom to work remotely, embracing diverse work styles, while NYC-based team members can opt for a hybrid setup, spending some days in the office to foster collaboration.
• Unlimited PTO & other time off benefits: Take the opportunity to rest and recharge. No questions asked — it's time to disconnect and come back stronger. Plus, paid sick days, your birthday off, and national holidays.
• Success stipend: We provide a renewable stipend on day one and every two years to create your perfect work setup — laptops, headphones, and more. It's about giving you the tools to do your best work.
• Comprehensive health benefits: Comprehensive health insurance reimbursement arrangement. No matter where you are, you're covered.
• Learning & development: We invest in your growth. Firstbase will pay for courses, events, and anything that helps you become better in your craft.

• Parental Leave: We support you through life's big moments — maternity, paternity, or adoption — with fully paid time off.
• Generous annual bonuses that grow: Expect a bonus that reflects your hard work — usually about 10% of your base salary in the first year. From your second year, a 20% annual multiplier boosts this, rewarding your consistent performance.
• Company Gatherings: We host annual retreats, quarterly in-person leadership planning, and occasional co-working days and happy hours — all fully covered to help us connect and have fun in person.
• Vacation bonus: After 3 years at Firstbase, you'll receive a generous vacation bonus to take that dream trip. It's our way of saying "thank you" for your commitment — we're here for the long haul, and we want you to enjoy the ride.
• Visa sponsorship: We support the best talent — wherever you are from. Firstbase offers visa sponsorship and renewal assistance if you are already in the US, or are looking to move to join our NYC-based team.
• Business travel & collaboration budget: Great work happens together. We cover team travel expenses so you can connect in person — whether it's a strategy sprint, team meetup, or just time to build stronger relationships.
• Upward mobility: We grow from within. When new roles open up, we look to our own team first — because we believe in recognizing potential, rewarding performance, and giving our people the opportunity to level up.
