Senior Frontend Engineer

Are you our next Senior Frontend Engineer? We're looking for an engineer who wants to help make logistics uncomplicated, fast, and accessible for small businesses across Europe.

At Sendify, we're on a mission to create a frictionless shipping experience for SMEs. As a Senior Frontend Engineer, you'll play a central role in shaping the web app where 4,000+ customers every week sign up, compare carrier rates, manage integrations, and book shipments.

You'll work end-to-end , from understanding a real customer problem with your PM and designer, to prototyping, to shipping production code, to owning what happens after the deploy. You'll lead frontend work on one of our three value teams (Customer Experience, Marketplace, or SaaS) and help raise the bar for frontend quality across the wider engineering team.

Your work will directly support Sendify's promise: saving time by making shipping as quick and easy as possible 🚀

• Have 8+ years of experience writing production frontend code, with the last 3+ at senior level in a scale-up/start-up, meaning you've led significant pieces of work without close supervision, and made architectural calls you can still defend with a growth mindset at the core of building
• Have deep React and TypeScript experience, opinions about state management, comfort reading a complex component tree, and the judgement to know when to reach for context vs. a store vs. URL state
• Have strong web fundamentals ;HTML semantics, modern CSS (Grid, Flexbox, container queries, design tokens), the browser rendering pipeline, and the network layer
• Treat accessibility as a practitioner skill, not a checklist , you've built interfaces that meet WCAG standards and can spot issues in design review before code is written
• Are fluent in web performance , you've measured Core Web Vitals on a real product, found the bottleneck, and shipped the fix
• Have testing maturity , you know what unit, integration, and end-to-end tests are each for, and don't over-rely on any one of them
• Have great written communication — most of our async work happens in writing (RFCs, PR descriptions, Slack threads), and sharp written reasoning matters
• Are fluent in written and spoken English

• Have worked in a monorepo at non-trivial scale
• Have logistics, marketplace, or B2B SaaS background
• Have contributed to building or evolving a design system
• Have experience embedding AI-assisted features into product UI
• Have working knowledge of Go, or are comfortable reading backend code at the API boundary
• Are fluent in Swedish or German

What you'll do:

• Plan and lead frontend development on sets of related stories within your value team, collaborating closely with the PM, designer, and backend engineers to figure out what should be built before reaching for the keyboard
• Translate designs into production user interfaces — accessible, performant, well-tested, and consistent with the rest of the product
• Build prototypes with the team, not for the team — putting working code in front of customers when the answer to a product question is unclear
• Own web performance on the surfaces you touch — Core Web Vitals are not a vanity metric for us, they correlate directly with booking conversion
• Champion accessibility — WCAG 2.2 AA is the baseline, not the ceiling
• Contribute to architecture decisions that cross the frontend/backend line — what belongs in the frontend vs. the BFF vs. the Go service, how integrations surface in the UI, how real-time updates work
• Help maintain shared standards across the React/TypeScript monorepo through PR review, the bi-weekly Tech Council, and the way you write your own code
• Mentor more junior engineers — through code review, pairing, and how you frame technical decisions
• Contribute to evolving our design system in collaboration with designers and other engineers

In this work you will use tools such as React, TypeScript, GitLab, AWS, Snowflake, Figma, Slack, JIRA, Notion, Claude Code, Fullstory etc.

Sendify is built on a curious, collaborative, and encouraging work environment where you should be able to express your thoughts and ideas, explore new directions, challenge, and get challenged. We value creativity across all disciplines.

We’re focused on bringing people together in a low-ego environment; we don’t believe in being stuck to a “one-way only” or that “this tech is the best”. The logistics industry is complicated and ever-changing; We move faster if we keep our minds open and adjust when needed.

In addition to our amazing culture, you’ll enjoy:

• Occupational pension
• Health benefits
• Accident and life insurance
• 4+1 work policy (4 days in the office, 1 day from home)
• Parental leave benefits
• 30 vacation days
• Half-day off before every public holiday
  

Logistics is built on handshakes, phone calls, and unread emails piling up in inboxes. Ever felt how easy it is to miss an important email? Now imagine running your entire business that way.

Sendify helps ambitious SMEs ship smarter. We wrap together real-time pricing, comparison, booking, and tracking in a clean and unified interface to allow customers to spend their time on their business, and not logistics.

And here’s the best part – we’re Great Place to Work certified! 🎉 This means we’re not just building great solutions for our customers, but also fostering an awesome, inclusive workplace where our team thrives. We believe that happy employees create the best experiences, and we’re proud to be recognized for it. ❤️
