About Gigs
At Gigs, we're building the operating system for mobile services—a platform that lets tech companies embed global connectivity into their products effortlessly.
Just as Stripe lets any business add a payment button in seconds, Gigs empowers platforms to weave in connectivity—bridging the traditional world of telecom with modern tech. From fintechs launching mobile services to HR platforms offering work phone plans, we automate provisioning and remove telecom complexity.
Our team of around 100 people across the US and Europe, backed by nearly $100 million in funding from Ribbit Capital, Google, and Y Combinator. As one of the fastest-growing tech companies, bringing together early-stage engineers, product builders, and business athletes from companies like Stripe, Airbnb, and Shopify. We’re tackling deep technical and regulatory challenges to make connectivity truly seamless.
If you’re driven by curiosity, creativity, and the chance to shape the future of telecom, we’d love to hear from you.
Things We Care About
We are building in a highly complex space and tackling a massive problem. We want people who lean in when things get hard.
- Speed. We move and we ship. We set bold deadlines and treat every week like it matters.
- Ownership. If you see something broken, fix it. We don't wait for permission.
- Customer Obsession. Our customers' product is our product.
- Ambiguity. We're building frontier technology in a complex domain. You'll need sound judgement and good instincts to make decisions without complete information.
- First principles. We don't ask how things have been done before. We ask why they were done that way at all.
The Role
- You will help build Connect, our consumer-facing hosted checkout and subscription management service, and related projects to deliver the best experience for our customers and their users.
- You will bring new ideas to directly shape our app development and products beyond our established work.
- You will work with a modern tech stack using Next.js, React, TypeScript and Tailwind CSS.
- You will use your skills for Frontend and Backend technologies built on top of Next.js.
- You will take ownership of features from planning and implementing to shipping and optimizing.
- You will work closely with our UI/UX team to develop the best possible experiences for our users.
- You will help design maintainable and scalable software architectures.
- You will give feedback, ideas, and code reviews to your colleagues.
- You will collaborate with colleagues across the engineering organization through cross-functional working groups and our RFC process.
Salary range: €85k - €120k.
What We Are Looking For
- You have advanced experience building web apps using React. You are a TypeScript pro, know your way around Next.js, and can implement common and advanced React patterns. You’ve been doing this for 5+ years. Working with git is natural for you.
- You enjoy building best-in-class experiences. You know what makes apps excellent, you can give your input and are able to implement the best possible UX.
- You have built and maintained scalable apps. You love to build things for scale and have experience in designing app architectures and writing high-quality code.
- You enjoy building a product from scratch. This means high involvement in the design process and understanding what customers want and users need.
- You love learning technologies as you go. You always want to find the right tool for the job, and not only follow what you already know.
- You care about more than engineering quality. Whatever you do, needs to have a business impact. You can make trade-offs between speed and quality.
- You are an all-rounder: You're fluent with RESTful APIs, worked with Docker, GCP, GitHub Actions, Cypress, or Testing Library, and have some experience with Ruby on Rails.
Work At Gigs
At Gigs, we value in-person collaboration. We believe the best ideas, decisions, and relationships are built when teams spend meaningful time together, and our culture is designed around that belief. We support flexibility where it makes sense. Some focused work can be done remotely, and not every role or week looks the same. You should expect regular time in one of our hubs, as well as occasional travel for team workshops, customer meetings, and Gigs Republic, our bi-annual company off-site. Our offices are designed to feel like home-inspired workspaces, with plants, thoughtful tools, and small, tight-knit teams that make collaboration feel natural, energizing, and effective.
What We Offer
At Gigs, we believe in rewarding excellence. We offer competitive compensation and stock options because we see you as a true partner in our growth. We also provide stipends for your home office or work setup, a budget for learning and development to fuel your career, and of course, a free phone and international data plan

- Collaborate with developers and product managers to drive quality from feature design through release.
- Contribute to release decisions with risk assessments and test coverage summaries.
- Partner with cross-functional teams to elevate quality across the SDLC.
- Identify and advocate for opportunities to expand test coverage across the organization.
- BS/MS in Computer Science, Engineering, or equivalent technical experience.

- Deep understanding of QA methodologies, processes, and CI/CD practices.
- Attention to detail with a bias toward risk-based testing.
- Strong problem-solving and debugging skills, including backend and frontend issue investigation.
- Ability to think like an end-user and test accordingly, especially when product requirements are minimal or evolving.
- Excellent communication skills and the confidence to constructively advocate for quality.
- Experience mentoring peers or contributing to testing infrastructure is a plus.
Compensation:
Compensation for this position includes a base salary, equity, and a variety of benefits. Actual salaries will be based on candidate-specific factors, including experience, skills, and location, as well as applicable local minimum pay requirements. We are actively hiring for this role in Berlin. For further details, please consult your recruiter.

Sales Development Representative (AI-Powered QA Automation)
Share this job
We're building an AI copilot for web testing automation. It enables manual and automation QA engineers to turn their manual testing flows into production-ready automated E2E testing scripts, saving hours of manual work and coding. We are a small team with zero bureaucracy, focusing on real users. We optimize for shipping value - not hype.
About the role:
You'll own the top of the funnel: outbound, qualification, and getting leads to sit down for a conversation. Demos, onboarding, and retention are staying with the founder for now.
Phase one: Get individual Automation QAs to try the product, aiming for fast adoption and no procurement. Once we hit 20+ weekly users, we’ll move on to phase two, where we’ll shift the focus to B2B – qualified meetings with QA Leads and Engineering Managers.
Your focus in the first three months:
- Build targeted lists: Automation QAs at companies with web products and Playwright, Cypress, or Selenium in their stack.
- Run outbound sequences (LinkedIn is the baseline, but you decide the channels). A/B test weekly.
- Design qualification gates (forms and scoring) to filter leads before the founder calls.
- Reach 20+ weekly active users after month one – ICP-qualified and giving direct feedback to engineering.
- Document what works into a repeatable playbook.
Growth path:
This role expands as your strategies deliver results. Once the user pipeline works, you can take over demos and run B2B sales end to end. From there, the natural next step is Growth Lead (funnel optimization and scaling the playbook) or Account Executive (owning deal execution).
Why to join:
- You'll be building a strategy that scales the product, not filling a quota. What you create from scratch becomes the foundation.
- Your outreach turns into users who talk directly to engineering, and their feedback ships as features within days.
- AI for developer tools is a market with real pull, and QA automation is one of its sharpest pain points.
- We’re backed by JetBrains – financially secure with no reliance on external VC funding.
Who we're looking for:
You should have a high level of agency and be quant-minded – you live in funnel metrics, run experiments, and are comfortable saying "no" to leads that are a bad fit.
The ideal candidate will:
- Have done 0-to-1 outbound for an early-stage devtool, QA tool, infrastructure product, or similar.
- Have proven cold outbound results, instead of being dependent on warm inbound.
- Be able to talk credibly about flaky tests, CI pain, and Playwright vs. Cypress. You don't need to be an engineer, but you do need domain empathy.
- Possess strong written communication skills, with the ability to craft short, sharp messages that get replies.
Nice to have:
- A QA or SDET background – you've felt the pain yourself before moving to sales or BD.
- Exposure to security/compliance objections – enough to pre-empt and route.
- Content skills – your LinkedIn posts get engagement, not just your DMs.
- Experience as one of the first 10 employees at a startup.

You bring:
-
3+ years of experience in manual QA, including structured test execution and regression testing

A product where quality directly impacts user trust

Strong manual QA foundation with room to grow automation skills

Close collaboration with Product and Engineering

A supportive, learning-focused environment
WHO THIS ROLE IS FOR
This role is for QA Analysts who want to:
-
Work on real, complex user journeys
-
Deepen their manual QA expertise

Grow automation skills step by step
-
Be part of a team that truly values quality
OUR PITCH
- #empathyculture: Become part of our international team with a scale-up atmosphere, where you as a person really count and your ideas and work make a real impact.
- #worklifeinbalance: Our working hours are flexible and family-friendly. Your main working hours are spent in the office, but you are also welcome to work from home from time to time.
