Who We Are Flosum is a bootstrapped, profitable B2B SaaS company building the leading Salesforce-native DevSecOps, Data Protection, and Security platform. Our solutions are trusted by Fortune 500 enterprises in the most heavily regulated industries on the planet — financial services, healthcare, government, and insurance. We’re not a startup burning cash and chasing vanity metrics. We’re a proven, scaling business that reached profitability on our own terms. As a Salesforce Summit Partner and Innovation Award winner, we’ve earned our seat at the table alongside the biggest names in enterprise software. Built 100% on the Salesforce platform. Serving enterprises that demand zero compromise on security, compliance, and reliability. Why This Role Exists We are entering an aggressive growth phase — expanding our product surface, deepening our platform capabilities, and accelerating our delivery velocity. We need senior-caliber Node.js developers who can own significant parts of our architecture and ship production code that enterprise customers depend on daily. This is not a staff augmentation seat. You will work directly with engineering leadership, product managers, and the CEO. Your decisions will have real consequences, your opinions will be heard, and your craftsmanship will be visible to the customers who rely on our platform. What You’ll Build High-performance backend services and APIs powering enterprise-grade SaaS applications Scalable, secure Node.js micro services and integrations within the Salesforce ecosystem Modern front-end experiences using Vue.js and TypeScript that serve demanding enterprise users CI/CD pipeline tooling, automation frameworks, and developer productivity infrastructure Real-time data processing and event-driven architectures handling sensitive enterprise data at scale Requirements Read this section carefully. We are specific about what we need because we are serious about who we hire. Non-Negotiable Technical Requirements 5+ years of professional Node.js development in production environments — not tutorials, not side projects, not bootcamp exercises. Real production systems serving real users at scale. Expert-level understanding of asynchronous programming, event loops, streams, and the Node.js runtime. You should be able to explain backpressure, the differences between setImmediate and process.nextTick, and why unhandled promise rejections are dangerous — without Googling it. Deep experience with TypeScript in production codebases. We write typed code, and we expect you to understand why. Strong command of RESTful API design, authentication patterns (OAuth 2.0, JWT), and API security best practices for enterprise environments. Proven experience with SQL and NoSQL databases, query optimization, data modeling, and understanding the performance implications of schema decisions at scale. Proficiency with Git workflows, code review practices, automated testing (unit, integration, and end-to-end), and CI/CD pipelines. Solid understanding of containerization (Docker), cloud services (AWS/GCP/Azure), and infrastructure-as-code principles. Highly Preferred (These Will Set You Apart) Salesforce development experience: Apex, Lightning Web Components (LWC), Visualforce, or Salesforce API integrations. If you know both Node.js and Salesforce, you are a rare and extremely valuable candidate to us. Experience building or contributing to Salesforce ISV (AppExchange) products. Vue.js front-end development experience, particularly with Vue 3 Composition API and state management. Experience working in B2B SaaS companies serving enterprise customers with strict compliance requirements (SOC 2, HIPAA, FedRAMP, GDPR). Familiarity with DevOps/DevSecOps toolchains and practices in the Salesforce ecosystem. The Kind of Person We’re Looking For Skills get you in the door. Mindset determines whether you thrive here: Missionary, Not Mercenary You care about what you’re building and why. You take ownership not because someone assigned it to you, but because that’s who you are. When something is broken at 2 AM, you don’t check whether it’s “your responsibility” — you fix it. Builder, Not a Bystander You don’t wait for perfect specifications. You dig in, ask hard questions, propose solutions, and ship. You would rather have a working prototype by Friday than a polished slide deck by next quarter. Craftsperson Under Pressure Enterprise customers depend on our uptime and data integrity. You write code that doesn’t just work — it survives. You understand that in regulated industries, your code is your reputation. Direct Communicator You say what you think, respectfully and clearly. If a technical decision is wrong, you speak up — regardless of who made it. We value candor over politeness-at-the-expense-of-quality. This Is a Long-Term Commitment Let us be direct: we are not looking for contractors who jump between projects every few months. We are building a world-class engineering team, and we invest heavily in the people who join us. In return, we expect commitment. This role is designed as a long-term, full-time engagement. You will grow with us. You will own systems end-to-end. You will see the direct impact of your work in how Fortune 500 companies build, protect, and deploy on Salesforce. If you’re looking for a short-term gig while you wait for something else, this isn’t the role. If you want to build something that matters and be part of a team that’s scaling from strong to dominant, keep reading. Benefits What We Offer Competitive compensation commensurate with your experience and impact Direct collaboration with the founding team and engineering leadership — your voice will carry weight from day one A profitable, stable company with aggressive growth plans — no funding anxiety, no runway clock The opportunity to work on enterprise-grade products used by some of the largest organizations in the world Meaningful technical challenges: security, compliance, scale, and reliability at the intersection of Node.js and Salesforce A culture that rewards ownership, speed, and craftsmanship over politics and hierarchy Remote-first flexibility with a results-oriented work environment Originally posted on Himalayas

仕事探しに関するよくある質問

英語の求人が表示されるのはなぜですか?

職種名や説明文は企業が作成したものです。条件や要件を変えないように原文を掲載しています。操作画面とこのガイドは日本語です。日本語の検索で見つからない場合は、「software engineer」のように、掲載言語の職種名やスキル名でも検索してみてください。検索語が自動翻訳されるわけではありません。

リモート求人なら、どの国からでも働けますか?

必ずしもそうではありません。居住国、就労資格、勤務時間帯が指定されている場合があります。元の求人ページで条件を確認してください。記載がない場合は、自分の居住地から応募できると判断する前に企業へ確認しましょう。リモートという表示だけでは、勤務地の制限がないことは分かりません。

検索結果が出ない場合はどうすればよいですか?

より一般的な職種名や一つのスキルで検索し、条件を一つずつ外してみてください。同じような仕事でも企業によって呼び方が異なります。特定の求人が見つからなくなった場合は、企業の採用ページで求人番号を探しましょう。検索条件を広げても、終了した募集が再開するわけではありません。

ResumizeAIから応募が送信されますか?

応募ボタンは外部サイトを開きます。企業または採用サービスの案内に従い、そのサイトで送信を完了してください。ResumizeAIで応募書類を作成しただけでは応募は送信されません。リンク先が企業のトップページの場合は、該当する募集を探してから手続きを進めましょう。

応募書類とカバーレターはどう調整すればよいですか?

募集要件と、自分が説明できるプロジェクト、業務、成果を結び付けます。経験していない技術や実績を加えず、関連する経験を分かりやすく示してください。カバーレターでは応募理由を具体例とともに伝えます。指定された言語とファイル形式に従い、送信前に両方の書類を確認しましょう。
