As we continue our rapid expansion, we are now looking for a Full-Stack Engineer to join us on a permanent basis and make an instant impact.
We’re looking for a Full-Stack Engineer to join our GTM (Go To Market) Activation team - a cross-functional group focused on increasing signup, integration, trial usage, and time-to-value for new users.
Your job is to work at the intersection of engineering, growth, and product, building everything from onboarding flows and self-serve dashboards to usage analytics, activation nudges, and backend services that guide users toward value - faster.
This team sits at the heart of our Go-To-Market engine. You’ll directly influence conversion and retention by reducing friction and turning passive signups into active users.
We’re a remote-first company with a fast-paced, high-impact culture. In this role, you’ll work closely with our CEO, Aurken, and our Director of Engineering. And as a business with two technical founders who have strong engineering backgrounds - you must be comfortable engaging in technical discussions while balancing business needs.
Build for Growth
- Ship full-stack features across the activation funnel: onboarding UI, guides, wizards, checklists, in-app messaging, and dashboards. Our tech stack: Laravel, Vue
- Own backend services and APIs that support analytics, tracking user progress, and onboarding personalization.
- Build self-serve capabilities (API explorers, data previews, sandbox flows) that increase integration rates.
Data & Instrumentation
- Implement robust event tracking using tools like Segment, Amplitude, BigQuery, and PostHog.
- Collaborate with Product and Growth to define and instrument key activation metrics.
- Work with analysts to surface insights and user segments for better targeting.
Experimentation & Optimization
- Run A/B tests and iterative experiments to improve signup, activation, and trial conversion.
- Based on usage data, build and test UX variations, email triggers, and behavioral nudges.
- Instrument cohort-based analysis to identify drop-offs and quick wins.
Cross-Functional Collaboration
- Partner with Product, Marketing, Sales, and Support to identify blockers and opportunities across the funnel.
- Act as a technical bridge between user-facing teams and the internal analytics tools.
- Help craft a frictionless developer experience from signup to first value.
Engineering Best Practices
- Write clean, maintainable, and performant full-stack code.
- Ensure smooth deployment and observability of new features (logs, alerts, error tracking).
- Maintain high standards for privacy, compliance, and security.
We’re looking for a builder obsessed with user onboarding, experimentation, and removing friction. You’re a data-driven engineer who understands product goals and loves seeing your work directly impact metrics that matter.
- Have +5 years of experience as a Full-Stack/Product Engineer, ideally with exposure to growth or product engineering.
- Have experience with modern frontend and backend development using React (or similar frameworks).
- Understand SaaS funnels - signup, onboarding, usage, activation, conversion.
- Have implemented behavioral analytics, event tracking, and activation dashboards.
- Have worked with tools like Amplitude, Segment, BigQuery, or PostHog.
- Are familiar with A/B testing tools and statistical analysis of experiments.
- Know how to balance speed with tech debt, and can ship fast while keeping things clean.
- Enjoy owning metrics and being measured by impact, not lines of code.
- Communicate clearly with product, growth, and marketing teams - and thrive on feedback.
- Have a strong design sensibility with experience creating polished, customer-facing interfaces that reflect brand values and marketing goals.
Bonus Points If You
- Have worked on activation or conversion at a B2B SaaS or API-based startup.
- Can explain concepts like time-to-value, North Star metrics, or growth loops.
- Have experience improving self-serve flows in technical products (developer-facing tools, APIs, dashboards).
- Have worked closely with design and marketing teams to implement customer-facing solutions that drive conversion.
- Demonstrate attention to detail with a portfolio that showcases pixel-perfect implementation of designs.
- You optimize workflows, reduce bottlenecks, and improve efficiency without overcomplicating processes.
- You understand the Pareto principle (80/20 rule) and prioritize high-impact work over perfection.
- You are used to working with multidisciplinary teams and balancing engineering, business, and product needs.
- You have world-class product sense and can prioritize engineering efforts based on business impact.
- You thrive in open, honest communication and ensure visibility across teams.
- You can handle strong opinions from technical founders and have the guts to say no when needed, while gathering input from multiple stakeholders.
- Excellent communication skills, with the ability to convey complex technical concepts to non-technical stakeholders.
- Full ownership. You'll own systems end-to-end — design, deployment, and operations. No handoffs to an ops team, no waiting for someone else to ship your work
- Direct impact. The systems you build directly affect customer SLAs, billing accuracy, and the core product success rate. You'll feel it
- No layers. You'll work closely with our CEO and Director of Engineering — both technically deep — without three layers of management in between
- No methodology theater. We skip the ceremony and give you a horizontal view of the problem. You decide where you can have the most impact
- Our people crave ownership and opportunity over everything else. We offer responsibility and scope to do things in your role that you can only dream of in similar roles in larger companies.
- We have a CEO who values world-class talent over everything else. Trust and respect are earned, and with them come reward and recognition like nowhere else.
- In a world where it feels like everyone is being called back to being in an office, we operate a truly 100% remote approach that allows you to work from anywhere you choose.
Forget Agile, Scrum, Lean... or whatever development methodology is trendy this week. We give you a horizontal view that enables you to identify where you think you can contribute the most.
We have fun! The above may sound like we are all about work, but we put a lot of focus on ensuring our culture is one that our people enjoy, which lets you build lasting friendships and grow both personally and professionally.
