About BlogVault

We are building a suite of SaaS products for websites—products with clear product-market fit, strong customer pull, and the potential to become $100M+ businesses.

Our frontend has reached a critical inflection point: we have upgraded our UI foundation, clarified our product direction, and established strong momentum. We are no longer just shipping isolated features. The next step is turning this foundation into a robust, consistent, and highly scalable frontend system that remains polished and dependable as our products grow.

About the role

This Frontend role is for someone who wants to own more than feature delivery. You will shape how frontend engineering works here: how product UI is built, how shared components evolve, how standards are set, how architecture decisions are made, and how AI-assisted development is used without compromising quality.

The Reality & The Mission

Our frontend is functional, but it is currently under-owned at the senior level. We are looking for a technical counterpart to partner with our UI engineer. You will focus on three key challenges:

• Systemic Architecture: Creating clear component boundaries and maintainable patterns to reduce technical debt in a fast-paced environment.
• UI Consistency: Maturing our shared component library so that visually complex workflows across our product suite feel polished, friendly, and robust.
• AI-First Guardrails: Designing the linting standards, automated validation, and review practices that allow us to leverage AI coding speed safely without code quality drift.

What You Will Own (Day 1)

• Frontend System Architecture: Define the structural patterns, boundaries, and long-term scalability of our React applications.
• Design-System Maturity: Build, mature, and drive adoption of a proper design-system foundation. Pair directly with our capable UI engineer to draw clean lines between design implementation and component engineering.
• AI-First Standards: Design and enforce code review standards that make AI-assisted velocity safe and sustainable.
• Theming & Variations: Refactor and upgrade shared component libraries to ensure they are reusable, extensible, and natively support brand-wise variations and light/dark modes.
• Technical Direction: Guide the day-to-day technical choices of the frontend team, raising the bar for reuse and execution quality.

Discovered Scope (What you will define)

• We want you to have the autonomy to analyze and build out:
• Frontend Observability: Select and implement the telemetry, error monitoring, and user-facing performance tools needed to keep our products healthy.
• Developer Experience (DX) Tooling: Design internal libraries, linters, or workflows that speed up local development cycles.

Who You Are

• You think in systems: You don’t just build components; you care about how code interacts over a multi-year horizon and value user-experience polish as much as code correctness.
• You are pragmatic: You know how to raise engineering standards and improve consistency without introducing heavy process overhead.
• You don’t outsource judgment: You use AI as a force multiplier but treat it as a tool that still requires rigorous engineering oversight and verification.
• You enjoy evolving live systems: You prefer refactoring and improving production systems over purely greenfield projects where the right answer is rarely "start over."

What We Expect You to Bring

• 4–5 years of experience building real-world frontend products in production.
• Strong hands-on experience with React JS and JSX.
• Deep fundamentals in modern JavaScript and React state management.
• Experience building, evolving, or maturing design systems and shared component libraries.
• Ability to structure clean API integrations and handle data synchronization.
• A collaborative mindset and a strong eye for visual polish.

Bonus Points If You Have Worked With:

• TypeScript
• Frontend observability, performance optimization, or error monitoring tools
• Theming systems, dark mode architecture, or multi-brand UI foundations
• Fast-growing SaaS product teams with high ownership and velocity

This Role is Probably Not For You If:

• You prefer narrowly scoped implementation work over broad systems ownership.
• You mainly enjoy greenfield projects and dislike refactoring or building on top of live products.
• You optimize for perfect, dogmatic abstraction over practical progress.
• You want frontend direction to be fully predefined for you.

Culture at BlogVault

Some values we’ve lived by over these last 14 years:

We think like inventors.

>Invent the answer you wish existed. If it already exists, ask how it could exist better.<

We build for the love of it. And we build the best.

We don’t just copy and paste. We start from first principles—frame the problem, question the default, ship, improve, repeat—until it’s world-class.

Every version and experiment is a chance to push past our comfort zone and hone our craft. It isn’t easy—it takes patience and persistence—but it ends in work we’re proud of.

Ownership builds a rocket ship.

>It’s not the hours you put in your work that count; it’s the work you put in the hours.<

We’re here to build the business. When we see a problem, we own it end‑to‑end. We pull in the right people, ask for help early, track just enough to finish, and close the loop. We focus on what moves the needle, cut low‑impact work, and push hard when it counts—then recover.

That focus builds subject mastery. It helps get in the flow. It fuels passion and can spark healthy friction—and that’s all part of the game. We make a fuss when it matters, and once a call is made, we commit to it fully—whether we all agree or disagree.

Step up to stand tall.

>Greatness is a moving target.<

Chase excellence in your craft and take on bigger problems. Grow into a full-stack problem-solver and leader—whatever your domain. Improve with intent, work with people who push you, and never get too comfortable. That’s how we level up.

How’s the team?

• Open and flat hierarchy
• High-agency work with a get-stuff-done attitude
• Teams that focus on creating wins - for the org, the team and yourself - all fuelled by mentorship and empowerment

Benefits

• Relocation benefits - we’ll book your domestic travel if you are not in Bangalore and help you with 2 weeks of accommodation
• Homemade lunch at the office and a pantry with snacks, fresh coffee & tea
• All the IT essentials and tools you’ll need to be successful in your role, everyone at the office gets an external monitor, ergonomic seating and a mechanical keyboard
• Frequent outings, company-sponsored outdoor events, celebrations for milestones, trips for the entire team and sponsorships to participate at international company events at exotic destinations
• Profit-sharing bonuses based on company growth, tenure and performance
• Paid time off - maternity, paternity, and marriage leave
• Insurance for the whole family
