You'll work in close partnership with our Product Engineers. This is a senior builder's role at the intersection of AI and biology. You'll work across the stack and across teams, set technical direction on the surfaces you own, mentor other engineers, and partner closely with R&D to ship software that makes our models usable and dependable. This is a technical (individual-contributor) leadership role — you lead by shipping complex features yourself, setting the technical bar through ownership, implementation, architecture, standards and mentoring through code reviews and pairing rather than direct reports. As the Product team grows, there's a path to take on people management if that's a direction you want; it is not a requirement of the role. WHAT YOU'LL BE DOING ---------------------------------------------------------------------------------------------------------------------------------- As a Technical Lead, you will have ownership over the following: Product Development (End to End): * Design, build, test, and ship features spanning back-end services and front-end interfaces for our B2B biology products. * Take features from idea to production and own them in operation, balancing speed with quality and maintainability. Back-End & Services: * Design and maintain robust, scalable services and APIs (REST, gRPC) that compose our packaged models into product capabilities. * Build data workflows and work fluently with our core stack (Python, SQL, and related technologies). Building on the SDK & Model Packages: * Build product on top of the SDK and model packages produced by our Product Engineers, and feed back what the product layer needs from those interfaces. Technical Leadership: * Set engineering patterns and standards for the surfaces you own, lead design on ambiguous, cross-cutting problems, and mentor other engineers through code review and pairing. AI-Assisted Development: * Use agentic coding tools (e.g., opencode, Claude) to accelerate delivery, and help shape how our team adopts AI-native development workflows. Cross-Functional Collaboration: * Work closely with Product Engineers and platform/infra engineers to align what we build with real scientific and customer needs. WHAT YOU'LL BRING ---------------------------------------------------------------------------------------------------------------------------------- The successful candidate is a seasoned, technically versatile engineer who ships high-quality software and raises the bar for those around them; they thrive in fast-paced environments and bring clarity to ambiguous problems. Technical Proficiency: * Advanced Python Proficiency: Several years of experience writing clean, well-tested, maintainable Python in production, with a track record of owning features end to end. * Full-Stack Capability: Strong across back-end services and comfortable with modern front-end development (JavaScript/TypeScript with a modern framework such as React, Vue, or similar). * Data & Storage: Solid working knowledge of SQL and designing sensible data workflows. * Cloud Deployment Expertise: Hands-on experience deploying applications and ML models in the cloud (AWS strongly preferred; GCP/Azure a plus) using containers (Docker, Kubernetes). * Software Engineering Fundamentals: Strong grasp of core computer science principles, data structures, and modern CI/CD workflows. Solution Design & Leadership: * Software Design & Architecture: Excellent grasp of object-oriented and functional design principles, with the ability to reason about and explain trade-offs between performance, simplicity, and modularity. * Setting Direction: Demonstrated experience setting technical patterns, leading design on cross-cutting work, and mentoring other engineers. * APIs & Integration: Experience designing and integrating APIs (e.g., REST, gRPC) to ship complex applications. * AI-Native Tooling: Comfortable working with agentic coding tools (e.g., opencode, Claude) as part of your day-to-day workflow.

Senior Software Engineer

Templafy

About us: Founded in Copenhagen, Denmark, in 2014, Templafy’s success is built by our 60+ employee nationalities found at offices around the world. We believe that when people feel valued, heard, and empowered, they perform at their best—creating a win for all. Our unique product and dedication to innovation and excellence have raised over $200 million in funding from top investors like Insight Venture Partners, Seed Capital, Dawn Capital, Damgaard Company and Golub Capital. About the role and company: I'm using AI to write the job posting, and I asked Codex to use the Slack connector to collect some "cultural proof points" about what it's like working at Templafy. This is what it came up with: Templafy engineering culture comes across as pragmatic, product-close, technically opinionated, and unusually open about trade-offs. · Engineers are expected to think like product builders, not just implementers. Threads often connect technical work to customer demos, pilots, product quality, adoption, and user feedback · Pragmatism is a real value. There’s repeated language around simple/explicit code, logical PR chunks, avoiding feature creep, solving the 80% case first, building MVPs, and getting something testable into users’ hands quickly · Quality matters, but in a practical way. Tests, E2E coverage, evals, pipeline health, flaky tests, feature-flag cleanup, and technical health all show up as shared concerns · Engineers are candid and trusted to challenge scope. I saw people questioning whether work should be bugs vs feature requests, whether backlog items are clutter, when to pause work, and when a “quick fix” is acceptable · Cross-functional collaboration is very present. PMs, design, solutions, support, security, platform, and product engineering are all in the same threads negotiating quality bars, customer urgency, UX, risk, and ownership · AI/tooling curiosity is strong, but not naive. The AI guild and engineering channels show people experimenting with code review agents, AGENTS.md, evals, Codex/Claude workflows, guardrails, and agentic SDLC, while also worrying about learning, friction, false positives, security, and long-term maintainability · There’s a bias toward async feedback and shared learning. Moving sprint review-style updates into short videos and Slack feedback is a good culture signal: fewer meetings, more continuous visibility · Ownership is distributed. People jump in to unblock, sanity-check, investigate, create PRs, clean up flags, or hand over work when someone is away. The tone is informal but accountable Small caution: I would avoid selling the culture as “perfectly polished.” The honest version is stronger: Templafy looks like a place where engineers have real agency, real product context, and real technical messes to improve. The rest of this job posting is probably more like what you'd expect. What You’ll Do In Product Engineering, you will help build and improve product experiences used by Templafy customers. You will work with product managers, designers, and other engineers to understand customer problems, shape solutions, and deliver features from idea through production. You will: * Build, improve, and maintain customer-facing product features * Collaborate with Product and Design to turn ambiguous problems into usable solutions * Use AI-assisted development tools thoughtfully as part of your everyday engineering workflow * Make technical decisions within your area and contribute to broader architecture discussions * Write reliable, maintainable code that fits existing patterns and systems * Use tests and fast feedback loops to support confident delivery * Build early versions of ideas to evaluate real behavior instead of debating hypotheticals * Help simplify product paths, remove complexity, and make features easier to test and maintain * Debug issues, improve performance, and support production systems * Help the team balance delivery speed, technical quality, and customer impact * Contribute to engineering practices, code reviews, and technical discussions What We’re Looking For We’re looking for someone who enjoys product context and wants to be part of shaping what gets built, not only how it gets built. You probably have: * Strong experience building production software in a product engineering team * Experience using AI-assisted engineering tools in real development work * The judgment to use AI tools without outsourcing your understanding of the system * Good technical judgment and the ability to make pragmatic trade-offs * Experience with modern web application development * A solid understanding of software design, testing, and maintainability * Comfort working across frontend, backend, or full-stack * Strong communication skills, especially in async and cross-functional settings * A bias toward making discussions concrete through prototypes, tests, and working software * A sense of ownership over outcomes, not just assigned tasks * The ability to challenge scope constructively and keep work focused Nice To Have * Experience with SaaS or B2B software * Experience with cloud platforms, CI/CD, observability, distributed systems * Experience building AI-enabled products, agentic workflows, evals, or prompt/tooling systems * Interest in improving developer experience, technical health, and team practices What You’ll Join You’ll join a product engineering team that cares about building useful software, learning quickly, and keeping the systems healthy enough that we can keep moving. We value people who can ask good questions, make things simpler, and help the team find the right trade-off when there is no perfect answer. This is a good role for someone who wants meaningful product ownership, close collaboration with non-engineering colleagues, and enough technical complexity to make simplification genuinely valuable. We are looking for someone who can move fast, but who also knows that the fastest teams are usually the ones that keep their systems understandable. Tech stack Backend: C# / .NET, ASP.NET Core, Entity Framework Core, SQL Server Frontend: TypeScript, React, HTML/CSS/SCSS AI: LLM integration & agentic AI (tool-calling, multi-agent) Cloud/Infra: Azure, Kubernetes, Docker, Terraform DevOps: Azure DevOps / Pipelines, Git Testing: xUnit, Playwright Employee Benefits:  * Employee equity program * Private health insurance * Company lunch contribution * Phone and broadband covered by company * Centrally located office – easy access to public transportation * Company events and team activities * Flexible work environment * Gympass Subscription * Calm App Subscription At Templafy, we’re all about building an inclusive culture where talented people come together to spark creativity in a dynamic, collaborative space. Strong relationships and teamwork are at the core of everything we do, and with our flat structure, everyone’s ideas count regardless of your role or experience. We’re big on social events that foster connection and build a diverse, empowering community. From celebrating milestones to participating in employee resource groups or eating lunch together, we create space for meaningful team bonding. Our mission goes beyond just building a product; we’re shaping the future, and we’d love for you to be a part of this epic journey with us. Templafy is a workplace of belongingness. To us this means that you have a voice, you dare to speak up, and your voice is heard. We focus on offering an environment that allows all employees to feel that they belong regardless of race, color, ancestry, religion, gender, gender identity, genetic information, parental or pregnancy status, national origin, sexual orientation, age, citizenship, marital status, disability, or other status.
