Why Vizcom Our mission is to reshape design by streamlining the path from concept to creation, bringing more impactful ideas into the physical world. We're well-funded (Series B $51m to date), growing double-digits MoM, and expanding the core engineering team in SF. The surface area is big: realtime collaboration, GPU inference at scale, a modern TypeScript stack, and serving real enterprise customers. The Role Take end to end ownership of critical product areas, from architecture through launch, and set the technical direction for how we build at scale. You will drive design reviews, ship prototypes that push our product forward, and establish pragmatic engineering standards that balance speed and quality. Beyond your own contributions, you will mentor teammates into future tech leads and help us grow a world class engineering culture as Vizcom scales. Interview Process (fast; no leetcode) Intro (30m): mutual fit, role/impact. Architectural deep-dive (60-75m): a real Vizcom problem; you drive the trade-offs. Hands-on working session (90m): pair on a small, realistic slice. Cross-functional chat (30m): product/design collaboration. Founder/CTO conversation (30-45m): values, scope, expectations. References & offer. (Optional paid work sample if preferred to a take-home.) (Key responsibilities) Set the architecture roadmap to keep Vizcom reliable, scalable, and a joy to develop in as usage, models, and data grow. Ship hands-on: jump into code for critical paths, rapid prototypes, and hairy debugging (latency, memory, race conditions, WebGL/WASM quirks). Install quality guardrails that scale: test strategy, code-review norms, perf budgets, observability baselines. Mentor and multiply: develop senior engineers into tech leads; model clear written design and crisp decision-making. Partner cross-functionally: represent engineering trade-offs with Product/Design/Go-To-Market and act as the CTO's delegate when needed. 90-Day Outcomes Reliability & perf: land an observability-driven plan for our top-5 critical flows. Reduce p95 for at least one user-visible flow by ~30% through targeted fixes (query plans, caching, batching, streaming, GPU/CPU boundaries). Architecture: author one substantial RFC (e.g., realtime doc model, rendering pipeline boundaries, or background job topology) and lead it to adoption. Team health: mentor two engineers with measurable growth (scope, design quality, or incident handling). Developer experience: remove one persistent friction (local env speed, CI flakiness, or flaky e2e surface) and document the standard. The Problems You'll Tackle High-fanout realtime collaboration (WebSockets/CRDT-style data models). GPU-backed image generation pipelines and queueing with bursty workloads. Performance across the stack: React/Vite bundles, GraphQL n+1s, Postgres query plans, caching at the right layer. Enterprise-grade SSO/SAML/SCIM, auditability, and secure multi-tenant boundaries. A design-forward UX that must still feel instant under load. (Qualifications) 8-12+ years building distributed web systems (TypeScript/Node preferred) with 2+ years at Staff scope. Depth with Postgres and performance/observability (profiling, traces, query tuning). Experience with container orchestration and production ops (K8s or equivalent). Bonus: realtime collaboration models, WebGL/WASM, GPU workloads, or enterprise identity (SSO/SAML/SCIM). How We Work Small team, high ownership. Fewer people, more leverage. Design-centric. We obsess over speed and feel; “fast enough” usually isn't. Write it down. RFCs, crisp decisions, living docs. Operate what you build. Everyone on call support; incidents drive improvement, not blame.

Early-stage startup with a focus on work-life balance and long-term thinking We're an early-stage startup. While the business needs mean we can't promise you a regular 40-hour workweek, we try our best to respect weekends, vacations, and life outside of work. We believe that Codex should serve its customers and employees long term - and that begins with ensuring employee burnout isn't a part of our employee life. Improving patient health outcomes is a difficult, long-term aspiration. This means we have to create a workplace that values long-term thinking, with near-term results that doesn't sacrifice employees' wellbeing. Remote-first company, with regular in-person events for Bay Area employees We recognize that the ability to work remotely is an employee benefit that significantly influences knowledge-workers lifestyles. It can define our quality of life. We're a remote-first company, with most people living in the San Fransisco Bay Area. We make an effort for San Fransisco **employees to regularly meet in person ****by hosting company Happy Hour events, coordinated co-working days, and more. While the remote work environment creates its own set of challenges (necessitating disciplined communication, building a shared context, maintaining a sense of connectedness, etc.), we see these as opportunities. We understand that traditional, in-office work environments were not the most inclusive spaces. Thus, we believe that hybrid remote work helps promote a diversified workforce with benefits and opportunities that far outweigh its challenges. Transparent, cross-collaborative, and open company culture Transparency - Weekly All-Hands with an “ask anything” opportunity Cross-collaboration - Biweekly Engineering standups Company Off-sites Recognition by company-wide demos of new engineering/product features Open Community - calendars are public so anyone can join almost any meeting or discussion Bottom Up engineering (and product and design) led organization - come to us with your ideas! High impact-to-engineer ratio, open communication, and support for personal growth We're a small team of collaborative individuals with a high impact-to-engineer ratio. Every individual - independent of job title - can make a large impact on any part of the business and materially improve patient health. We dream big and we want to help each other succeed and reach our career goals. We do this through encouraging open communication, empathetic feedback, sharing ideas, listening to each other's perspectives, being available for bespoke 1:1s, and having an overall willingness to work together toward a shared learning environment. We get to work with modern, cutting-edge technologies and systems aimed at revolutionizing the healthcare industry. We also believe that technologies must be used to ensure the privacy and data security of patients. Lastly, we care more about productive work than how you work; giving you the flexibility to discover what's most productive for you. Commitment to diversity, equity, and inclusion

About Eventual Every breakthrough AI application, from foundation models to autonomous vehicles, relies on processing massive volumes of images, video, and complex data. But today's data platforms (like Databricks and Snowflake) are built on top of tools made for spreadsheet-like analytics, not the petabytes of multimodal data that power AI. As a result, teams waste months on brittle infrastructure instead of conducting research and building their core product. Eventual was founded in 2022 to solve this. Our mission is to make querying any kind of data, images, video, audio, text, as intuitive as working with tables, and powerful enough to scale to production workloads. Our open-source engine, Daft, is purpose-built for real-world AI systems: coordinating with external APIs, managing GPU clusters, and handling failures that traditional engines can't. Daft already powers critical workloads at companies like Amazon, Mobileye, Together AI, and CloudKitchens. We've assembled a world-class team from Databricks, AWS, Nvidia, Pinecone, GitHub Copilot, Tesla, and more, quadrupling our size within a year. With Series A and seed funding from Felicis, CRV, Microsoft M12, Citi, Essence, Y Combinator, Caffeinated Capital, Array.vc, and top angels from the co-founders of Databricks and Perplexity, we're looking to double the team now. Join us-Eventual is just getting started. Please note we're looking for individuals who are excited to be a part of a tight-knit team working together 4 days / week in our SF Mission district office.

You will ship features that will be immediately used by our customers and will work with a tight-knit team that values open communication and cross-functional collaboration. We move quickly to solve a wide range of complex technical and product challenges. While we are an experienced team that can provide constant guidance and mentorship, we value engineers who can autonomously scope and solve difficult technical challenges.
