Senior Product Engineer

• Own the production outcome, including reliability, observability, supportability, and working within Semaphore 's security and compliance requirements. Communicate decisions, progress, and risks clearly.

What we are looking for

• A track record of independently shipping meaningful software products or major product capabilities.

• Strong product judgment: you can identify the essential user problem, reduce unnecessary scope, and recognize when an experience is good enough to ship—or not good enough yet.

• Strong engineering judgment across system design, implementation, reliability, and long-term maintainability.

• Strong backend and systems fundamentals, including APIs, asynchronous processing, service boundaries, state and lifecycle management, retries, idempotency, and failure recovery.

• Comfort with infrastructure concepts such as virtual machines, storage, networking, authentication, secrets, containers, and cloud platforms.

• Ability to navigate a polyglot environment. Semaphore systems include Go, Elixir, Ruby, React, and related technologies; expertise in every language is not required.

• Enough frontend capability to build or extend focused product user experiences without depending on a separate team for every change.

• Fluency with modern AI-assisted development: decomposing work for agents, supplying useful context, reviewing generated changes, and building verification into the workflow.

• Initiative and persistence. You make progress with incomplete information, surface risks early, and bring in other people when their input will improve the result.

• Strong written and spoken English and experience working independently in a remote, asynchronous team.

We care more about the quality and ownership of what you have built than a specific number of years, previous title, or exact match with our stack.

Nice to have

• Experience building developer tools, CI/CD systems, cloud platforms, or infrastructure products.

• Hands-on experience with distributed systems and event-driven architectures.

• Experience evolving a mature codebase while introducing a new product or architecture alongside it.

• Experience in a lean environment where senior engineers participate directly in product discovery and customer conversations.

What success looks like

Within your first three months:

• You have taken ownership of a meaningful product problem and shipped a useful capability to production.

• Your work shows good product taste, clear technical decisions, and disciplined scope.

• You have learned enough of Semaphore 's existing platform to reuse its strengths and avoid unnecessary reinvention.

• You are using AI coding agents to increase your output while keeping the resulting systems understandable, tested, and reliable.

• Product and engineering decisions move faster because you bring clear options, make sound calls, and follow through.

• The team trusts you with an ambiguous new product or feature and expects you to drive it to a strong result.

How you will work

This is a senior individual-contributor role with broad ownership. You will work closely with engineering, product, infrastructure, and company leadership. Teams are small, communication is direct, and the person closest to the work is expected to exercise judgment.

You will have room to shape both the product and its implementation. In return, we expect you to take responsibility for the whole outcome: what gets built, why it matters, how well it works, and what happens after it ships.
